+# Contributing
+
+If you want to contribute, please make sure you've executed the tests.
+
+
+### How to write new provider?
+- create the provider filer under `/lib/provider`
+- create the corresponding config both in `config/config.example` and `config/config.test.json` 
+- make sure the selector matches and that the needed fields are available
+- create a test under /test and make sure it is running successfully 
+
+### How to write new notification adapter?
+- create the provider filer under `/lib/notification/adapter`
+- make sure it exports a function `enabled` and a function `send`
+- create the corresponding config both in `config/config.example` and `config/config.test.json` 
+
+#### Running Tests
+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`
+
+##### To do before merging:
+
+- executed tests? (`npm run test`)
+- executed reformat? (`npm run format`)
+- sure the changes are useful for everybody? Or is it maybe a custom modification just for your case?
+
+_Thanks!_ :heart:

+# Fredy
+
+[F]ind [R]eal [E]states [D]amn Eas[y] :heart:
+
+My wife and I wanted to buy an apartment in germany. As the prices are quite high and good deals are very rare, we searched the "big 4" every morning.   
+
+This however can get pretty frustrating. _Fredy_ will take this work away from you. It crawls the `provider`, mentioned below (Immonet, Immoscout...) every _x_ minutes. (The provider list can be extended easily...)   
+
+If _Fredy_ found matching results, it will send them to via Slack. (More adapter possible.) _Fredy_ is remembering what it already has found to not send stuff twice.
+
+## Usage
+
+- Make sure to use Node 8 and above
+- Install the dependencies using `npm install`
+- create your configuration file. Use the example config for this. `cp conf/config.example conf/config.json`
+- configure the desired values
+- start _Fredy_ using `npm start`
+
+
+## Configuration
+
+Before running _Fredy_ for the first time, you need to create a configuration file:
+
+Copy the example config as a start.
+```
+cp conf/config.example conf/config.json
+```
+
+### 1. Notification
+
+You want to get notified when _Fredy_ found a new listing. Currently _Fredy_ support Slack to send notification. _Fredy_ also includes a notification adapter to print to the console instead of sending to a services.
+
+Adding new notification adapter is easy however. See [Contribution](https://github.com/orangecoding/fredy/blob/master/CONTRIBUTION.md) 
+```json
+"slack": {
+  "channel": "someChannel",
+  "token": "someToken",
+  "enabled": true
+}
+```
+
+### 2. Configure the providers
+
+Configure the providers like described below. To disable a provider just remove its entry from the configuration or set it to `false`.
+
+#### Ebay Kleinanzeigen, Immoscout, Immowelt, Immonet and Kalaydo
+
+```json
+"kleinanzeigen": {
+    "url": "https://www.ebay-kleinanzeigen.de/...",
+    "enabled": true
+}
+"immoscout": {
+  "url": "https://www.immobilienscout24.de/...",
+  "enabled": true
+},
+"immowelt": {
+  "url": "https://www.immowelt.de/...",
+  "enabled": true
+},
+"immonet": {
+  "url": "http://www.immonet.de/...",
+  "enabled": true
+},
+"kalaydo": {
+  "url": "http://www.kalaydo.de/...",
+  "enabled": true
+},
+```
+
+Go to the respective provider page and create your custom search queries by
+using the provided filter options. Then just copy and paste the whole URL of
+the resulting listings page.
+
+**IMPORTANT:** Make sure to always sort by newest listings! This way _Fredy_ makes sure to not accidentally report stuff twice.
+
+#### Custom provider
+
+See [Contribution](https://github.com/orangecoding/fredy/blob/master/CONTRIBUTION.md)
+
+### 3. Add Filters (optional)
+
+
+#### Blacklist
+
+```json
+"blacklist": [
+  "vermietet"
+]
+```
+
+Listings which contain at least on of the given terms (ignoring case, only
+whole words) are removed. 
+
+#### District blacklist
+```json
+"blacklistedDistrics": [
+  "Altstadt"
+]
+```
+Districts that are unwanted can be blacklisted here. 
+
+This makes sense for provider that only offer limited filter functions like Kalaydo/Ebay.
