Configuring mobile apps to work with wallabag

Steps to configure the app

First create a new client in the API clients management section. The name of your app doesn't matter as much as the Client ID and the Client secret. Write these two values down.
When you download a mobile app, it's going to ask for the server address of the hosted wallabag instance. For example, with wallabag.it that is: https://app.wallabag.it.
It's also going to ask for the aforementioned Client ID and secret. Please insert those in the text fields, when asked.
Lastly you need to provide your username and password. These are the same credentials you use to login in to wallabag.

Please also have a look at Android page. Especially the section on known limitations.
