-# Fredy β Self-Hosted Real Estate Search & Alerts for Germany
+# Fredy π‘ β Your Self-Hosted Real Estate Finder for Germany
-Searching for an apartment or house in Germany can be frustrating.
-Fredy makes it easier: it scrapes **ImmoScout24, Immowelt, Immonet, eBay Kleinanzeigen, and WG-Gesucht**, and notifies you instantly via **Slack, Telegram, Email, ntfy, and more** when new listings match your requirements.
+Finding an apartment or house in Germany can be stressful and

-## Understanding the fundamentals
+------------------------------------------------------------------------
-There are 3 important parts in Fredy, that you need to understand to leverage the full power of _Fredy_.
+## π§© Core Concepts
-#### Provider
+Fredy is built around three simple concepts:
-_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!**
+### Provider π
-#### Adapter
+A **provider** is a real-estate platform (e.g.Β ImmoScout24, Immowelt,
+Immonet, eBay Kleinanzeigen, WG-Gesucht).\
+When you create a job, you paste the search URL from the platform into
+Fredy.\
+β οΈ Always make sure the search results are sorted by **date**, so Fredy
+picks up the newest listings first.
-_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.
+### Adapter π‘
-#### Jobs
+An **adapter** is the channel through which Fredy notifies you (Slack,
+Telegram, Email, ntfy, ...).\
+Each adapter has its own configuration (e.g.Β API keys, webhook URLs).\
+You can use multiple adapters at once --- Fredy will send new listings
+through all of them.
-A Job wraps adapters and providers. _Fredy_ runs the configured jobs in a specific interval (can be configured in `/conf/config.json`).
+### Job π
-## Creating your first 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`).
-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.
+------------------------------------------------------------------------
-## User management
+## Immoscout
-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.
+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)
-# Development
+## Analytics
-### Running Fredy in development mode
+Fredy is completely free (and will always remain free). However, it would be a huge help if youβd 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.
-Start the backend with:
+**Thanks**π€
-```shell
+## π οΈ Development
+
+### Development Mode
+
+``` bash
yarn run start:backend:dev
-```
-
-For the frontend, run:
-
-```shell
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.
