-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).

-
-_Fredy_ is supported by JetBrains under Open Source Support Program
-
-## Demo
-
-If you want to try out _Fredy_, you can access the demo version [here](https://fredy.orange-coding.net) 🤘
-
-## Usage
-
-- Make sure to use Node.js 20 or above

-There are 3 important parts in Fredy, that you need to understand to leverage the full power of _Fredy_.
 
-#### Provider
+# Fredy 🏡 – Your Self-Hosted Real Estate Finder for Germany
 
-_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!**
+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, and more** when new
+listings appear.
 
-#### Adapter
+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.
 
-_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.
 
-#### 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
+## ✨ 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.
+-   🏠 Scrapes **ImmoScout24, Immowelt, Immonet, eBay Kleinanzeigen,
+    WG-Gesucht**
+-   ⚡ Instant notifications: Slack, Telegram, Email (SendGrid,
+    Mailjet), ntfy
+-   🔎 Uses the **ImmoScout Mobile API** (reverse engineered)
+-   🌍 Runs anywhere: Docker, Node.js, self-hosted
+-   🖥️ Intuitive **Web UI** to manage searches
+-   🎯 Easy to use thanks to a user-friendly Web UI
+-   🔄 Deduplication across platforms
+-   ⏱️ Customizable search intervals
 
-## 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.

+
+## 🧩 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, ...).\
+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**🤘
+
