 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).

 ## Understanding the fundamentals
 There are 3 important parts in Fredy, that you need to understand to leverage the full power of _Fredy_.
 
-#### 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.   
+#### 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!**
 
-#### 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.

 ### 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.
+Immoscout has implemented advanced bot detection. I’m actively working on bypassing these measures, but until then, selecting Immoscout as a provider will not return any results. I apologize for the inconvenience. 😉
 
-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 :)
-
-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).

-See [Contributing](https://github.com/orangecoding/fredy/blob/master/CONTRIBUTING.md)

-### Monitoring
-
-_Fredy_ can be monitored by [Instana](https://www.instana.com). If you are interested, sign up for a free trial. This is totally optional of course :)  
-If you want to use Instana to monitor _Fredy_, please change the variable `INSTANA_MONITORING` in the `.env` file to `true`.
+# 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 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.</p>
