+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Fredy is a self-hosted real estate finder for Germany. It scrapes German real estate portals (ImmoScout24, Immowelt, Immonet, Kleinanzeigen, WG-Gesucht, etc.), deduplicates results across providers, and sends notifications via Slack, Telegram, Email, Discord, ntfy, etc. It includes a React web UI and a built-in MCP server for LLM access to listings data.
+
+- Node.js >= 22, ESM-only (`"type": "module"`)
+- Default port: 9998, default login: admin / admin
+- SQLite via `better-sqlite3` (synchronous - all DB ops are sync; only network I/O is async)
+
+## Commands
+
+```bash
+# Development
+yarn run start:backend:dev    # nodemon backend
+yarn run start:frontend:dev   # Vite dev server (proxies /api → :9998)
+
+# Production
+yarn run start:backend        # NODE_ENV=production node index.js
+yarn run build:frontend       # vite build → ui/public/
+
+# Tests
+yarn test                     # Live tests (hits actual providers)
+yarn test:offline             # Offline tests using HTML/JSON fixtures (fast, preferred)
+yarn test:download-fixtures   # Re-download fresh provider HTML fixtures
+
+# Single test file
+TEST_MODE=offline npx vitest run test/provider/immoscout.test.js
+
+# Lint / Format
+yarn lint && yarn lint:fix
+yarn format && yarn format:check
+
+# DB migrations
+yarn migratedb

+```
+
+### Plugin systems
+
+**Providers** (`lib/provider/*.js`) - each module exports:
+- `metaInformation` - `{ id, name, baseUrl }`
+- `config` - `ProviderConfig` with `requiredFieldNames`, `crawlContainer`, `crawlFields`, `sortByDateParam`, `normalize()`, `filter()`, optional `getListings()`, `fetchDetails()`, `activeTester()`
+- `init(sourceConfig, blacklist)` - called before each job run; providers are **stateful modules** holding mutable `url` and `appliedBlackList` at module scope
+
+**Notification adapters** (`lib/notification/adapter/*.js`) - each exports:
+- `config` - `{ id, name, description, fields }` (drives the UI form)
+- `send({ serviceName, newListings, notificationConfig, jobKey, baseUrl })`
+- Loaded dynamically at startup via `fs.readdirSync`
+
+### Key services
+
+| Service | Location | Notes |
+|---|---|---|
+| Event bus | `lib/services/events/event-bus.js` | Plain `EventEmitter`; events: `jobs:runAll`, `jobs:runOne`, `jobs:status` |
+| SSE broker | `lib/services/sse/sse-broker.js` | Per-userId `Set<ServerResponse>`; heartbeat every 25s; pushes job status to UI |
+| Similarity cache | `lib/services/similarity-check/` | In-memory SHA-256 Set; refreshes hourly; cross-provider dedup by title+price+address |
+| SqliteConnection | `lib/services/storage/SqliteConnection.js` | Singleton, WAL mode; `execute()`, `query()`, `withTransaction()` |
+| Migrations | `lib/services/storage/migrations/` | Numbered JS files each exporting `up(db)`; checksum-tracked in `schema_migrations` |
+| Extractor | `lib/services/extractor/` | Orchestrates Puppeteer + Cheerio; shared browser instance per job |
+
+### Frontend
+
+- React 19 SPA, Vite build → `ui/public/` (served as static by backend)
+- State: Zustand single store with per-domain slices
+- UI library: `@douyinfe/semi-ui`
+- Map: MapLibre GL + `@mapbox/mapbox-gl-draw` + `@turf/boolean-point-in-polygon` for GeoJSON polygon filters
+- In dev: Vite proxies `/api` to `:9998`
+
+### MCP server
+
+Two transports:
+1. **stdio** (`lib/mcp/stdio.js`) - for Claude Desktop/LM Studio; opens its own DB connection (main process need not be running)
+2. **HTTP** (`/api/mcp`) - authenticated via Bearer token (`mcp_token` column in `users` table)
+
+Tools: `list_jobs`, `get_job`, `list_listings`, `get_listing`, `get_current_date_time`. Responses are Markdown via `lib/mcp/mcpNormalizer.js`.
+
+## Key Conventions
+
+- **ESM only** - `import`/`export` everywhere, no CommonJS
+- **JSDoc typedefs** (no TypeScript) in `lib/types/` - `listing.js`, `job.js`, `filter.js`, `providerConfig.js`
+- **Copyright header** required on all `.js` files - enforced by `lint-staged` pre-commit hook via `copyright.js`
+- **`NoNewListingsWarning`** (`lib/errors.js`) is used as control flow to short-circuit the pipeline (not an error)
+- **Test fixtures** in `test/testFixtures/` - HTML/JSON snapshots per provider; `TEST_MODE=offline` mocks `puppeteerExtractor` and global `fetch` via `test/offlineFixtures.js`
+- **`conf/config.json`** is the only runtime config file; created with defaults if missing
+
+## Coding
+- After building the task, run the linter
+- After building the task, run the tests
+- New features must be tested
+- New features must be properly documented with JsDoc
+- You do **not** commit any changes, you do **not** create a new branch unless I told you so

-Searching an apartment in Germany can be a frustrating task. Not any longer though, as _Fredy_ will take over and will only notify you once new listings have been found that match your requirements.
-
-_Fredy_ scrapes multiple services (Immonet, Immowelt etc.) and send new listings to you once they become available. The list of available services can easily be extended. For your convenience, _Fredy_ has a UI to help you configure your search jobs.
-
-If _Fredy_ finds matching results, it will send them to you via Slack, Email, Telegram etc. (More adapters can be configured.) As _Fredy_ stores the listings it has found, new results will not be sent to you twice (and as a side-effect, _Fredy_ can show some statistics). Furthermore, _Fredy_ checks duplicates per scraping so that the same listings are not being sent twice or more when posted on various platforms (which happens more often than one might think).

-#### Provider
 
-_Fredy_ supports multiple services. Immonet, Immowelt and Ebay are just a few examples. Those services are called providers within _Fredy_. When creating a new job, you can choose one or more providers.
-A provider contains the URL that points to the search results for the respective service. If you go to immonet.de and search for something, the displayed URL in the browser is what the provider needs to do its magic.
-**It is important that you order the search results by date, so that _Fredy_ always picks the latest results first!**
 
-#### Adapter
+# Fredy 🏡 – Your Self-Hosted Real Estate Finder for Germany
 
-_Fredy_ supports multiple adapters, such as Slack, SendGrid, Telegram etc. A search job can have as many adapters as supported by _Fredy_. Each adapter needs different configuration values, which you have to provide when using them. An adapter dictates how the frontend renders by telling the frontend what information it needs in order to send listings to the user.
+Finding an apartment or house in Germany can be stressful and
+time-consuming.\
+**Fredy** makes it easier: it automatically scrapes **ImmoScout24,
+Immowelt, Immonet, eBay Kleinanzeigen, and WG-Gesucht** and notifies you
+instantly via **Slack, Telegram, Email, ntfy, discord and more** when new
+listings appear.
 
-#### Jobs
+With a modern architecture, Fredy provides a **clean Web UI**, removes
+duplicates across platforms, and stores results so you never see the
+same listing twice.
 
-A Job wraps adapters and providers. _Fredy_ runs the configured jobs in a specific interval (can be configured in `/conf/config.json`).
+------------------------------------------------------------------------
 
-## Creating your first job
+## ✨ Key Features
 
-To create your first job, click on the button "Create New Job" on the job table. The job creation dialog should be self-explanatory, however there is one important thing.
-When configuring providers, before copying the URL from your browser, make sure that you have sorted the results by date to make sure _Fredy_ always picks the latest results first.

+------------------------------------------------------------------------
+
+## 🧩 Core Concepts
+
+Fredy is built around three simple concepts:
+
+### Provider 🌐
+
+A **provider** is a real-estate platform (e.g. ImmoScout24, Immowelt,
+Immonet, eBay Kleinanzeigen, WG-Gesucht).\
+When you create a job, you paste the search URL from the platform into
+Fredy.\
+⚠️ Always make sure the search results are sorted by **date**, so Fredy
+picks up the newest listings first.
+
+### Adapter 📡
+
+An **adapter** is the channel through which Fredy notifies you (Slack,
+Telegram, Email, ntfy, discord ...).\
+Each adapter has its own configuration (e.g. API keys, webhook URLs).\
+You can use multiple adapters at once --- Fredy will send new listings
+through all of them.
+
+### Job 📅
+
+A **job** combines providers and adapters.\
+Example: "Search apartments on ImmoScout24 + Immowelt and send results
+to Slack + Telegram."\
+Jobs run automatically at the interval you configure (see
+`/conf/config.json`).
+
+### MCP Server 🤖
+
+Starting with **V20**, Fredy ships with a built-in **MCP Server **. This allows you to connect Fredy to LLMs (like Claude, ChatGPT, or local models via LM Studio) and query your real estate data using natural language.
+The local LLM can even enrich existing listings by checking the listing online.   
+
+For more information on how to set it up and use it, please refer to the [MCP Readme](lib/mcp/README.md).
+
+------------------------------------------------------------------------
+
+## Immoscout
+
+Immoscout has implemented advanced bot detection. In order to work around this, we are using a reversed engineered version of their mobile api. See [Immoscout Reverse Engineering Documentation](https://github.com/orangecoding/fredy/blob/master/reverse-engineered-immoscout.md)
+
+## 🛡️ Bot Detection & Proxies
+
+Most browser-based providers (immowelt, immonet, kleinanzeigen, ...) are scraped through a hardened headless browser ([CloakBrowser](https://www.npmjs.com/package/cloakbrowser)). It makes the **browser fingerprint** indistinguishable from a real Chrome, which is enough when you run Fredy on a normal home connection.
+
+On a **server / VPS the requests usually originate from a datacenter IP**, and providers behind anti-bot systems (e.g. AWS CloudFront/WAF) block those based on **IP reputation alone**, no matter how perfect the fingerprint is. The typical symptom: it works locally but you get `We have been detected as a bot :-/` on the server.
+
+### The fix: a residential proxy
+
+A **residential proxy** routes Fredy's browser through the internet connection of a real household, so the provider sees a "normal user" IP instead of a datacenter. For German portals, use a **German (DE) residential** (or mobile/4G) proxy. Plain VPNs and **datacenter proxies do not help** here, they share the same bad reputation as your server.
+
+**Configure it** under **Settings → Execution → Proxy URL**. Supported formats:
+
+```
+http://user:pass@host:port
+socks5://user:pass@host:port
+```
+
+Leave the field empty to disable. The proxy applies to all headless-browser providers and takes effect on the next job run (no restart needed). Immoscout uses a separate mobile API and is not affected.
+
+### Where to get a residential proxy
+
+Residential proxies are a paid service (usually billed per GB, Fredy's traffic is small). Well-known providers offering German residential IPs include:
+
+| Provider | Notes |
+|---|---|
+| [IPRoyal](https://iproyal.com) | Pay-as-you-go, no monthly minimum, good for low volume |
+| [Webshare](https://www.webshare.io) | Cheap entry tier, has a small free plan to test with |
+| [Decodo (formerly Smartproxy)](https://decodo.com) | Easy setup, country/city targeting |
+| [SOAX](https://soax.com) | Residential + mobile, fine-grained geo-targeting |
+| [Bright Data](https://brightdata.com) | Largest pool, most features, higher complexity/price |
+| [Oxylabs](https://oxylabs.io) | Enterprise-grade, larger plans |
+
+This is not an endorsement, pick whatever fits your budget. For low-volume use like Fredy, a pay-as-you-go plan (e.g. IPRoyal) or a cheap entry tier (e.g. Webshare) is usually plenty. Make sure to select **Germany** as the proxy location and keep the search interval reasonable (the higher the interval, the less you look like a bot).
+
+## Analytics
+
+Fredy is completely free (and will always remain free). However, it would be a huge help if you’d allow me to collect some analytical data.
+Before you freak out, let me explain...  
+If you agree, Fredy will send a ping once every 6 hours to my internal tracking project (Will be open sourced soon).  
+The data includes: names of active adapters/providers, OS, architecture, Node version, and language. The information is entirely anonymous and helps me understand which adapters/providers are most frequently used.</p>
+
+**Thanks**🤘
+
+## 🛠️ Development
+
+### Development Mode
+
+``` bash
+yarn run start:backend:dev
 yarn run start:frontend:dev
 ```
-
 You should now be able to access _Fredy_ from your browser. Check your Terminal to see what port the frontend is running on.
 
-### Running Tests
+### Run Tests
 
-To run the tests, run
-
-```shell
+## "Online" tests
+These tests are directly executed against the actual providers.
+``` bash
 yarn run test
 ```
 
-# Architecture
+## "Offline" tests
+These tests are using the test fixtures instead of the actual providers. Much faster and "good enough" to test the core functionality.
+``` bash
+yarn run test:offline
+```
 
-```mermaid
+## Download new fixtures
+If you have to refresh the fixtures (every once in a while needed because the providers change their code), run this command:
+``` bash
+yarn run download-fixtures
+```

+## 🤖 Using AI such as Claude Code
+When I started building Fredy, LLMs were still basically the wet dream of a few nerdy scientists.
 
-Immoscout has implemented advanced bot detection. In order to work around this, we are using a reversed engineered version of their mobile api. See [Immoscout Reverse Engineering Documentation](https://github.com/orangecoding/fredy/blob/master/reverse-engineered-immoscout.md)
+Nowadays, it’s easier than ever to throw a prompt into the LLM of your choice and let 'the AI' build your stuff. I’m not against that. I use Claude Code myself for smaller tasks, and I do think these tools can be really useful.
 
-# Analytics
+That said, I still believe humans should stay in charge. AI is great-ish at writing code, but it still lacks creativity, context, and the ability to see the full picture.
 
-Fredy is completely free (and will always remain free). However, it would be a huge help if you’d allow me to collect some analytical data.
-Before you freak out, let me explain...  
-If you agree, Fredy will send a ping to my Mixpanel project each time it runs.  
-The data includes: names of active adapters/providers, OS, architecture, Node version, and language. The information is entirely anonymous and helps me understand which adapters/providers are most frequently used.</p>

+ # Fredy MCP Server
+
+The Fredy MCP Server exposes your real estate jobs and listings data to LLM clients. It supports two transports:
+
+- **Stdio**: for local LLM clients (Claude Desktop, LM Studio, llm-cli, mcp-cli, etc.)
+- **Streamable HTTP**: for remote LLM clients (ChatGPT, cloud-hosted agents, etc.)
+
+## Authentication
+
+All MCP access is **token-based** based. Every Fredy user is automatically assigned a **permanent, non-expiring MCP token** when their account is created. This token is a secret and should be treated like a password.
+
+### Where to find your token
+
+MCP tokens are displayed in the **User Management** list (Admin → Users). Each user's token is shown in the **"MCP Token"** column.
+
+> **Important:** MCP tokens never expire. They are permanent secrets tied to each user account. If a token is compromised, you must change the token! If you chose to use a token from an admin account, the LLM can query information from ALL jobs/listings. 
+
+## Available Tools
+
+| Tool | Description                                                                    |

+
+## Usage with Local LLM (stdio transport)
+
+The stdio transport communicates over stdin/stdout and is ideal for local LLM tools.
+
+### Quick Start
+
+```bash
+MCP_TOKEN=fredy_<your-token> node mcp/stdio.js
+# or
+MCP_TOKEN=fredy_<your-token> yarn mcp:stdio
+```
+
+### Testing with MCP Inspector
+
+The [MCP Inspector](https://github.com/modelcontextprotocol/inspector) lets you interactively test your MCP server in a browser UI.
+
+```bash
+npx @modelcontextprotocol/inspector -e MCP_TOKEN=fredy_<your-token> -- node mcp/stdio.js
+```
+
+Once the inspector is running, open the URL shown in your terminal (usually `http://localhost:6274`). You can then:
+1. Click **Connect** to establish the stdio connection
+2. Go to the **Tools** tab to see all available tools
+3. Select a tool, fill in parameters, and click **Run** to test it
+
+### LM Studio Configuration
+
+[LM Studio](https://lmstudio.ai/) supports MCP servers natively, allowing your local LLM to access Fredy's jobs and listings data.
+
+#### Setup
+
+1. Open **LM Studio** and load a model that supports tool use (e.g., Qwen 2.5, Llama 3.1, Mistral, etc.)
+2. In the right side  under **Integrations** click on "# install" and "edit mcp.json"
+3. Edit the LM Studio MCP config file directly (`~/.lmstudio/config/mcp.json` or via the UI export):
+
+   ```json
+   {
+     "mcpServers": {
+       "fredy": {
+         "command": "node",
+         "args": ["/absolute/path/to/fredy/mcp/stdio.js"],
+         "env": {
+           "MCP_TOKEN": "fredy_<your-token>"
+         }
+       }
+     }
+   }
+   ```
+
+4. Toggle the server **on**: LM Studio will spawn the stdio process and connect
+5. You should see the Fredy tools appear as available tools
+
+#### Suggestion on LLM
+After testing numerous LLM's, I got the best results with Qwen 3.5 or Qwen 2.5.. E.g. `Qwen2.5-14B-Instruct-1M-8bit`.
+
+#### Usage
+
+Once connected, simply ask your LLM about your real estate data in natural language:
+
+- *"Show me all my active search jobs"*
+- *"List the latest listings from my Berlin apartment search"*
+- *"Get details for listing XYZ"*
+- *"What are the cheapest listings across all my jobs?"*
+
+The LLM will automatically call the appropriate Fredy MCP tools and present the results.
+
+> **Tip:** Make sure Fredy is running and the database is accessible before starting the MCP server in LM Studio. The stdio transport initializes its own database connection, so Fredy's main process does not need to be running, but the database file must exist and be up-to-date (migrations applied).
+
+### Claude Desktop Configuration
+
+[Claude Desktop](https://claude.ai/download) supports MCP servers natively via its developer settings.
+
+#### Setup
+
+1. Open **Claude Desktop**
+2. Go to **Settings → Developer → Edit Config** - this opens the `claude_desktop_config.json` file
+3. Add the `fredy` server to the `mcpServers` object:
+
+   ```json
+   {
+     "mcpServers": {
+       "fredy": {
+         "command": "/opt/homebrew/opt/node@22/bin/node",
+         "args": ["/absolute/path/to/fredy/lib/mcp/stdio.js"],
+         "env": {
+           "MCP_TOKEN": "fredy_<your-token>"
+         }
+       }
+     }
+   }
+   ```
+
+   Replace `/absolute/path/to/fredy` with the actual path on your machine (e.g. `/Users/you/dev/fredy`).
+
+   > **Important:** Claude Desktop launches with a restricted `PATH` and often cannot find `node` by name. Always use the **full absolute path** to the node binary. Find yours by running `which node` in a terminal. Common locations:
+   > - Homebrew (default): `/opt/homebrew/bin/node`
+   > - Homebrew (versioned, e.g. node@22): `/opt/homebrew/opt/node@22/bin/node`
+   > - nvm: `/Users/<you>/.nvm/versions/node/<version>/bin/node`
+
+4. Save the file and **restart Claude Desktop**
+5. You should see a hammer icon (🔨) in the chat input - click it to confirm the Fredy tools are listed
+
+#### Usage
+
+Once connected, simply ask Claude about your real estate data:
+
+- *"Show me all my active search jobs"*
+- *"List the latest listings from my Berlin apartment search"*
+- *"What are the cheapest apartments added this week?"*
+
+Claude will automatically call the appropriate Fredy MCP tools.
+
+> **Note:** Fredy's main web process does not need to be running - the stdio transport opens its own database connection directly. But the SQLite database file must exist and migrations must have been applied.
+
+---
+
+## Usage with Remote LLM (Streamable HTTP transport)
+
+The HTTP transport is automatically available when Fredy is running. It uses the MCP Streamable HTTP protocol at:
+
+```
+POST   /api/mcp   – JSON-RPC messages (initialize, tool calls)
+GET    /api/mcp   – SSE stream for server-initiated notifications
+DELETE /api/mcp   – Terminate session
+```
+
+### Authentication
+
+All requests must include the token as a Bearer token:
+
+```
+Authorization: Bearer fredy_<your-token>
+```
+
+### Example: Initialize a session
+
+```bash
+curl -X POST http://localhost:9998/api/mcp \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer fredy_<your-token>" \
+  -d '{
+    "jsonrpc": "2.0",
+    "id": 1,
+    "method": "initialize",
+    "params": {
+      "protocolVersion": "2025-03-26",
+      "capabilities": {},
+      "clientInfo": { "name": "test-client", "version": "1.0.0" }
+    }
+  }'
+```
+
+### Example: Call a tool
+
+```bash
+curl -X POST http://localhost:9998/api/mcp \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer fredy_<your-token>" \
+  -H "Mcp-Session-Id: <session-id-from-init-response>" \
+  -d '{
+    "jsonrpc": "2.0",
+    "id": 2,
+    "method": "tools/call",
+    "params": {
+      "name": "list_jobs",
+      "arguments": { "page": 1, "pageSize": 10 }
+    }
+  }'
+```
+
+## Security
+
+- Every user is automatically assigned a permanent MCP token at account creation – **tokens never expire**
+- Tokens are cryptographically random (256-bit) and prefixed with `fredy_`
+- Each token is scoped to a single user – the LLM can only access that user's data
+- Non-admin users only see their own jobs and jobs shared with them
+- Tokens are stored in the `mcp_token` column of the `users` table
+- Tokens are deleted automatically when the owning user is removed
+- The `/api/mcp` endpoint uses Bearer token auth (independent of cookie-session)
+- Treat MCP tokens like passwords – do not share them publicly
+
+## Response Format
+
+All tool responses use **markdown** instead of JSON for maximum LLM readability and token efficiency:
+
+- **List responses** (list_jobs, list_listings) use markdown tables with a summary line and pagination footer
+- **Detail responses** (get_job, get_listing) use markdown key-value lists
+- **Error responses** include the tool name and error message
+
+Example list response:
+
+```
+**Tool:** list_listings | **Status:** OK
+
+Found **85** listing(s). Showing page 1 of 2 (50 on this page). More pages available - use page=2 to continue.
+
+| ID | Title | Address | Price | Size | Provider | Active | Created | Job |
+|----|-------|---------|-------|------|----------|--------|---------|-----|
+| abc123 | Nice flat | Berlin | 1200 | 70 | immoscout | yes | 2026-02-25 10:30:00 | My Search |
+| ... | ... | ... | ... | ... | ... | ... | ... | ... |
+
+Use **get_listing** with an ID for full details (description, link, image).
+
+**Page:** 1/2 | **Has more:** yes
+```
+
+Example detail response:
+
+```
+**Tool:** get_listing | **Status:** OK
+
+### Listing: Nice flat
+
+- **ID:** abc123
+- **Title:** Nice flat
+- **Address:** Berlin
+- **Price:** 1200
+- **Size:** 70
+- **Provider:** immoscout
+- **Link:** https://...
+- **Active:** yes
+- **Created:** 2026-02-25 10:30:00
+```
+
+Markdown is used because it is significantly more token-efficient than JSON (~40-60% fewer tokens for tabular data) and natively understood by all LLMs.

+You can leverage this adapter to integrate with various webhooks or APIs that accept HTTP requests. (e.g. Supabase

+
+HTTP adapter supports a `authToken` field, which can be used to include an authorization token in the request headers.

+
+Resend is a modern email delivery service that Fredy can use to send notifications.
+
+Setup:
+- Create a Resend account: https://resend.com/
+- Create an API key and add it to Fredy's configuration.
+- Choose the sender address (e.g., you@yourdomain.com). Verify the domain (https://resend.com/domains/) in Resend before using it.
+- Optional for local testing: you can use `onboarding@resend.dev`, but Resend may restrict who you can send to when using test domains.
+
+Multiple recipients:
+- Separate email addresses with commas (e.g., some@email.com, someOther@email.com).
+
+Notes & Troubleshooting:
+- Ensure the `from` address is verified or belongs to a verified domain in Resend.
+- If emails don't arrive, check your spam folder and Resend dashboard logs.
+- The template displays listing images via their public URLs; make sure images are reachable.

+### SMTP Adapter
+
+Send notifications through any SMTP server using [Nodemailer](https://nodemailer.com/).
+This works with Gmail, Outlook, self-hosted mail servers, or any provider that supports SMTP.
+
+Setup:
+
+- Provide the SMTP host and port of your mail server.
+- For **SSL/TLS** (port 465), set Secure to `true`.
+- For **STARTTLS** (port 587), leave Secure empty or set it to `false`.
+- Enter the username and password for authentication. For Gmail, use an [App Password](https://support.google.com/accounts/answer/185833).
+- Set the sender email address (must be allowed by your SMTP server).
+
+Multiple recipients:
+
+- Separate email addresses with commas (e.g., `some@email.com`, `someOther@email.com`).
+
+Common SMTP settings:
+
+- **Gmail** - `smtp.gmail.com`, port 587, secure: false
+- **Outlook** - `smtp.office365.com`, port 587, secure: false
+- **Yahoo** - `smtp.mail.yahoo.com`, port 465, secure: true
+- **Gmx** - `mail.gmx.net`, port 587, secure: true

 ### Telegram Adapter
 
-For Telegram, you need to create a Bot. This is pretty easy. Open [this](https://telegram.me/BotFather) url on your smartphone and follow the instructions.
+Use this adapter to send notifications to Telegram via a bot. You will need:
+- A Telegram Bot token (from BotFather)
+- A chat ID (where messages will be sent)
+- Optionally: a thread ID if you want to post into a specific forum topic in a group
 
-A telegram bot is not allowed to send messages directly to a user, you as a user need to first contact the bot to get a chatId.  
-After the user has send a message to your bot the first time, you can gather the chatId like this:
+#### Create a bot
+Create a bot with BotFather: open https://telegram.me/BotFather on your phone or in Telegram Desktop and follow the instructions to get your bot token.
 
+#### Getting the chat ID
+A Telegram bot cannot message a user first; you must create a conversation (or add the bot to a group/channel) so Telegram assigns a chat the bot can access.
+
+Steps:
+1. Start a chat with your bot in Telegram (or add the bot to your group/supergroup/channel) and send any message.
+2. Fetch recent updates from the Bot API:
+   ```
+   curl -X GET "https://api.telegram.org/bot{YOUR_TELEGRAM_TOKEN}/getUpdates"
+   ```
+3. In the JSON response, find the message that you just sent and read `message.chat.id`. That value is your `chatId`.
+   - Private chats: `chat.id` is a positive number
+   - Groups/supergroups: `chat.id` is a negative number
+
+Keep your bot token secret. If `getUpdates` returns an empty list, send a new message and try again, or make sure your bot’s privacy settings allow it to see group messages when used in groups.
+
+#### Getting the thread ID (this is optional to be used for forum topics)
+If you want messages to appear inside a specific forum topic of a supergroup with Topics enabled, you also need a thread ID. In the Telegram Bot API this is called `message_thread_id`.
+
+When you need it:
+- Required only for supergroups with Topics enabled when targeting a topic
+- Not used for private chats, basic groups without Topics, or channels
+
+Steps to obtain it:
+1. In your supergroup, enable Topics (Group settings → Manage group → Topics → Enable). Now add a new topic.
+2. Add your created bot to the topic. (Click on the bot and on "Add to group")
+3. Open the desired topic (or create a new one) and send any message inside that topic.
+4. Call `getUpdates` again:
+   ```
+   curl -X GET "https://api.telegram.org/bot{YOUR_TELEGRAM_TOKEN}/getUpdates"
+   ```
+4. In the update for the message you sent inside the topic, read `message.message_thread_id`. That number is your `threadId` for this topic.
+
+Example (truncated):
 ```
-curl -X GET https://api.telegram.org/bot{YOUR_TELEGRAM_TOKEN}/getUpdates
+{
+  "message": {
+    "chat": { "id": -1001234567890, "type": "supergroup" },
+    "message_thread_id": 42,
+    "text": "hello from the topic"
+  }
+}
 ```
+Use `chat.id` as `chatId` and `message_thread_id` as `threadId` in your configuration.
