+###### [V5.5.0]
+
+- Upgrading dependencies
+- fixing provider
+- allow multiple instances of 1 provider
+- **BREAKING**: Minimum node version is now 16
+
+###### [V5.4.6]
+
+- Adding Instana node.js monitoring
+-
+
+###### [V5.4.5]
+
+- Adding Instana node.js monitoring
+
+###### [V5.4.4]
+
+- Add support for Immo Südwest Presse (immo.swp.de)
+- Telegram: Use job name instead of ID and link in title
+- Fix race condition if user ID is in session but not in user store
+- Allow visiting the original provider URL
+
+###### [V5.4.3]
+
+- re-writing readme
+- improving docker build
+- using github's actions to build docker and test automatically
+
+###### [V5.4.2]

+- Fixing prod build
+
+###### [V5.4.1]
+
+- Upgrading dependencies
+- Provider urls are now automagically been changed to include the correct sort order for search results
+
+```
+Note: It has been an point of confusion since the very beginning of Fredy, that people simply copied the url, but
+did not take care of sorting the search results by date. If this is not done, Fredy will most likely not see the latest
+results, thus cannot report them. This release fixes it by adding the necessary params (or replaces them).
+```
+

-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`

-If _Fredy_ found matching results, it will send them to you via Slack, Email, Telegram etc. (More adapter possible.) As _Fredy_ will store the listings it has found, new results will not be sent 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 when posted on various platforms. (Happens more often than one might think)
 
-## Usage  
 
-- Make sure to use NodeJs 12 and above
-- Run the following commands
-```ssh
-yarn (or npm install)
-yarn run prod
-yarn run start
+# Fredy 🏡 – Your Self-Hosted Real Estate Finder for Germany
+
+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

+------------------------------------------------------------------------
+
+## 🧩 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
-I have added **experimental** support for Immoscout. Immoscout is somewhat special, coz 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 the check, I'm using a service called [ScrapingAnt](https://scrapingant.com/). The trick is to use a headless browser, rotating proxies and (once successful validated) re-send the cookies each time.
 
-To be able to use Immoscout, you need to create an account at ScrapingAnt. Configure the ApiKey in the "General Settings" tab (visible when logged in as administrator).
-The rest should be done by _Fredy_. Keep in mind, the support is experimental. There might be bugs and you might not always get pass the re-capture check, but most of the time it works pretty good :)
+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)
 
-If you need more that the 1000 api calls you can do per month, I'd suggest opting for a paid account... ScrapingAnt loves OpenSource, therefor they've decided to give all _Fredy_ users a 10% discount by using the code **FREDY10** (No I don't get any money for recommending good services...)
+## 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>
 
-## Understanding the fundamentals
-There are 3 important parts in Fredy, that you need to understand leveraging the full power of _Fredy_.
+**Thanks**🤘
 
-#### Adapter
-_Fredy_ supports multiple services. Immonet, Immowelt and Ebay are just a few. Those services are called adapter within _Fredy_. When creating a new job, you can choose 1 or many adapter.    
-An adapter holds the url that points to the search results for the service. If you go to immonet.de and search for something, the shown url in the browser is what the adapter needs to do it's magic.   
-**It is important that you order the search results by date, so that _Fredy_ always picks the latest ones first**
+## 🛠️ Development
 
-#### Provider
-_Fredy_ supports multiple provider. Slack, SendGrid, Telegram etc. A search job can have as many provider as supported by _Fredy_. Each provider needs different configuration values, which you have to provide when using it. A provider itself dictactes how the frontend renders by telling the frontend what information it needs in order to send listings to the user.
+### Development Mode
 
-#### Jobs
-A Job wraps adapter and provider. _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's one important thing.
-When configuring adapter, 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.

-## User management
-As an administrator, you can create/edit and remove user from _Fredy_. Be careful, each job is connected to the user that has created the job. If you remove the user, the jobs will also be removed.

-
-# Development
-
-### Running Fredy in dev mode
-To run _Fredy_ in dev 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
+``` bash
+yarn run start:backend:dev
+yarn run start:frontend:dev
 ```
-You should now be able to access _Fredy_ with your browser. Go to `http://localhost:9000`
+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
-To run the tests, simply run
-```shell
+### Run Tests
+
+``` bash
 yarn run test
 ```
 
-# Architecture
-![Architecture](/doc/architecture.jpg "Architecture")
+------------------------------------------------------------------------
 
-## Immoscout 
-I have added EXPERIMENTAL support for Immoscout. Immoscout is somewhat special, coz 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 the check, I'm using a service called [ScrapingAnt](https://scrapingant.com/).
+## 📐 Architecture
 
-To be able to use Immoscout, you need to create an account and copy the apiKey into the config file under /conf/config.json.
-The rest should be done by _Fredy_. Keep in mind, the support is experimental. There might be bugs and you might not always get pass the re-capture check, but most of the time
-it works pretty good :)

- 
-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:

+### Slack Adapter (Webhooks)
+
+*IMPORTANT:*
+This is the recommended Slack adapter. The old Slack adapter is unmaintained and kept only for backward compatibility.
+
+Setup:
+- Create a Slack account and workspace if you don't have one: https://slack.com
+- Create a channel where you want to receive notifications.
+- Add the Incoming Webhooks integration to that channel and copy the Webhook URL.
+- In Fredy, configure the Slack Webhook adapter with this URL.

 ### 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.

+ * - 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).
