-Finally create an account at [OpenWeather](https://home.openweathermap.org).
-On that website create an API key and paste it into the according setting in the Weather
-notification app.

+# OpenAudible
+
+[OpenAudible](https://openaudible.org/) is a cross-platform audiobook manager for the audible
+audiobook and podcast service.
+
+## Setup
+
+The software can be setup via installation files for [Windows](/wiki/windows.md), Mac and 
+[Linux](/wiki/linux.md) that are available on the
+[official website](https://openaudible.org/download).
+Linux distributions may aswell feature a package.
+
+After the installation the user has to connect OpenAudible with Audible.
+The `Connect to Audible` button is available under the `Controls` tab.
+
+## Usage
+
+This section describes various topics regarding the usage of OpenAudible.
+
+### Downloading, Converting and Splitting Audiobooks
+
+To download, convert or split an audiobook first make sure OpenAudible is connected with Audible as
+described in the [setup section](#setup).
+Also a library sync can be useful if the target audiobook doesn't show up in the list at the bottom
+of the window.
+A sync can be started by pressing the `Quick Audible Library Sync` button under the `Controls` tab.
+
+To download locate the audiobook in the list of audiobooks, right-click it and select `Download`.
+After the download it can be converted to `.mp3` or `.m4b` by selecting the corresponding option in
+the right-click menu.
+The same way the audiobook can be split.
+
+### Licensing and Avoiding It
+
+OpenAudible is a licensed product.
+The first year after installation the new versions can be downloaded and used without charge.
+However the versions that come out after this year are subject to the purchase of a license to use
+them.
+This means that the last version that was released before the end of the first year can be used
+indefinitely.
+This effectively lets the user use all features like
+[converting and splitting audiobooks](#downloading-converting-and-splitting-audiobooks) that are
+otherwise bound to a valid license.
