+## Enable Pocket Support
+
+If you'd like to use the `Add to Pocket` button on the feeds then you can do so by following the steps mentioned below:
+
+* Create a new Pocket Application
+  - https://getpocket.com/developer/apps/new
+
+* Take the `consumer key` and put it in `etc/get-pocket-token.py`
+  - https://github.com/mzfr/yarr/blob/master/etc/get-pocket-token.py#L5
+
+* Run the python script
+  - You'll need to have python3 installed.
+
+* Once the script runs, it will give you a URL, click on it and authorize the application.
+* After the scripts execution stops, you will have a `access_token`.
+
+
+### Manual Method
+
+If the you don't wanna run the script you can also get the `access_token` manually. For that please follow the steps mentioned [here](https://getpocket.com/developer/docs/authentication)
