-If you've written a new provider you are an awesome person. You know it and I do. If you now write tests for it, you are even more awesome. And who doesn't want to be more awesome right?
 
-To write tests for provider, you need to use Node 8 as the tests are using `async / await`

-![Build Status](https://github.com/orangecoding/fredy/actions/workflows/test.yml/badge.svg)
-
-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).
-
-## Usage  
-
-- Make sure to use Node.js 12 or above
-- Run the following commands:
-```ssh
-yarn (or npm install)
-yarn run prod
-yarn run start
-```
-_Fredy_ will start with the default port, set to `9998`. You can access _Fredy_ by opening your browser at `http://localhost:9998`. The default login is `admin`, both for username and password. You should change the password as soon as possible when you plan to run Fredy on a server.

-## Understanding the fundamentals
-There are 3 important parts in Fredy, that you need to understand to leverage the full power of _Fredy_.
+<p align="center">
+  <a href="https://fredy.orange-coding.net/" target="_blank">Website</a>&nbsp;&nbsp;|&nbsp;&nbsp;
+  <a href="https://fredy-demo.orange-coding.net/" target="_blank">Demo</a>
+</p>
 
-#### Adapter
-_Fredy_ supports multiple services. Immonet, Immowelt and Ebay are just a few examples. Those services are called adapters within _Fredy_. When creating a new job, you can choose one or more adapters.    
-An adapter 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 adapter 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!**

+</p>
 
-#### Provider
-_Fredy_ supports multiple providers, such as Slack, SendGrid, Telegram etc. A search job can have as many providers as supported by _Fredy_. Each provider needs different configuration values, which you have to provide when using them. A provider dictactes how the frontend renders by telling the frontend what information it needs in order to send listings to the user.
 
-#### Jobs
-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
-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 adapters, 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.
+# Fredy 🏡 – Your Self-Hosted Real Estate Finder for Germany
 
-## User management
-As an administrator, you can create, edit and remove users from _Fredy_. Be careful, each job is connected to the user that has created the job. If you remove the user, their jobs will also be removed.
+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.
 
-# Development
+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.
 
-### Running Fredy in development mode
-To run _Fredy_ in development mode, you need to run the backend & frontend separately. Run the backend in your favorite IDE, the frontend can be started from the terminal.
-```shell
-yarn run dev

+
+## 🧩 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**🤘
+
+## 🛠️ 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.
+
+### Run Tests
+
+``` bash
 yarn run test
 ```
 
-# Architecture
-![Architecture](/doc/architecture.jpg "Architecture")
+------------------------------------------------------------------------
 
-### Immoscout
-I have added **experimental** support for Immoscout. Immoscout is somewhat special, because they have decided to secure their service from bots using Re-Capture. Finding a way around this is barely possible. For _Fredy_ to be able to bypass this check, I'm using a service called [ScrapingAnt](https://scrapingant.com/). The trick is to use a headless browser, rotating proxies and (once successfully validated) to re-send the cookies each time.
+## 📐 Architecture
 
-To be able to use Immoscout, you need to create an account at ScrapingAnt. Configure the API key in the "General Settings" tab (visible when logged in as administrator).
-The rest will be handled by _Fredy_. Keep in mind, the support is experimental. There might be bugs and you might not always pass the re-capture check, but most of the time it works rather well :)

+        F2["Adapter 2"]
+  end
 
-If you need more than the 1000 API calls allowed per month, I'd suggest opting for a paid account... ScrapingAnt loves OpenSource, therefore they have decided to give all _Fredy_ users a 10% discount by using the code **FREDY10** (Disclaimer: I do not earn any money for recommending their service).

 ### SendGrid Adapter
 
- 
-SendGrid is a free email service (free as in "you cannot send more than 100(Sendgrid) and 200(Mailjet) emails a day"), which is more than enough for Fredy.
-   
-To use [SendGrid](https://sendgrid.com/), you need to create an account. You'll need to decided from which email address you want Fredy to send from. E.g. if you use yourGmailAccount@gmail.com, you have to add this to sendgrid and verify it as well.     
+SendGrid is an email delivery service with a generous free tier, which is more than enough for Fredy.
 
-Lastly you have to create an api-key and feed it into Fredy's config, as well as creating a new dynamic template. For this new template, I recommend copying and pasting the code from the one I have provided under `/lib/notification/emailTemplate/template.hbs`.
+Setup:
+- Create a SendGrid account: https://sendgrid.com/
+- Decide which email address Fredy should send from (e.g., yourGmailAccount@gmail.com), add it to SendGrid, and complete the verification.
+- Create an API key and add it to Fredy's configuration.
+- Create a Dynamic Template in SendGrid. You can copy the template from `/lib/notification/emailTemplate/template.hbs`.
 
-If this email should be sent to multiple receiver use a comma separator (some@email.com, someOther@email.com).
+Sending to multiple recipients:
+- Separate email addresses with commas (e.g., some@email.com, someOther@email.com).

 ### 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.
-  
-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:   
+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
 
-```  
-curl -X GET https://api.telegram.org/bot{YOUR_TELEGRAM_TOKEN}/getUpdates  
-```  
-  
-A more detailed list of instructions can be found here [https://core.telegram.org/bots#botfather](https://core.telegram.org/bots#botfather)
+#### 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):
+```
+{
+  "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.

+ * ImmoScout provider using the mobile API to retrieve listings.
+ *
+ * The mobile API provides the following endpoints:
+ * - GET /search/total?{search parameters}: Returns the total number of listings for the given query
+ *   Example: `curl -H "User-Agent: ImmoScout_27.3_26.0_._" https://api.mobile.immobilienscout24.de/search/total?searchType=region&realestatetype=apartmentrent&pricetype=calculatedtotalrent&geocodes=%2Fde%2Fberlin%2Fberlin `
+ *
+ * - POST /search/list?{search parameters}: Actually retrieves the listings. Body is json encoded and contains
+ *   data specifying additional results (advertisements) to return. The format is as follows:
+ *   ```
+ *   {
+ *   "supportedResultListTypes": [],
+ *   "userData": {}
+ *   }
+ *   ```
+ *   It is not necessary to provide data for the specified keys.
+ *
+ *   Example: `curl -X POST 'https://api.mobile.immobilienscout24.de/search/list?pricetype=calculatedtotalrent&realestatetype=apartmentrent&searchType=region&geocodes=%2Fde%2Fberlin%2Fberlin&pagenumber=1' -H "Connection: keep-alive" -H "User-Agent: ImmoScout_27.3_26.0_._" -H "Accept: application/json" -H "Content-Type: application/json" -d '{"supportedResultListType": [], "userData": {}}'`
+
+ * - GET /expose/{id} - Returns the details of a listing. The response contains additional details not included in the
+ *   listing response.
+ *
+ *   Example: `curl -H "User-Agent: ImmoScout_27.3_26.0_._" "https://api.mobile.immobilienscout24.de/expose/158382494"`
+ *
+ *
+ * It is necessary to set the correct User Agent (see `getListings`) in the request header.
+ *
+ * Note that the mobile API is not publicly documented. I've reverse-engineered
+ * it by intercepting traffic from an android emulator running the immoscout app.
+ * Moreover, the search parameters differ slightly from the web API. I've mapped them
+ * to the web API parameters by comparing a search request with all parameters set between
+ * the web and mobile API. The mobile API actually seems to be a superset of the web API,
+ * but I have decided not to include new parameters as I wanted to keep the existing UX (i.e.,
+ * users only have to provide a link to an existing search).
