-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`).
+
+------------------------------------------------------------------------
+
+## 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)
+
+## 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**🤘
+

+### HTTP Adapter
+
+This is a generic adapter for sending notifications via HTTP requests.
+You can leverage this adapter to integrate with various webhooks or APIs that accept HTTP requests. (e.g. Supabase
+Functions, a Node.js server, etc.)
+
+HTTP adapter supports a `authToken` field, which can be used to include an authorization token in the request headers.
+Your token would be included as a Bearer token in the `Authorization` header, which is a common method for securing API requests.

 ### 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.
