 Note that in case the current master branch is ahead of the latest release, it might happen that there are some incompatibilities when loading data from your local XPipe installation.
 You should therefore always check out the matching version tag for your local repository and local XPipe installation.
 You can find the available version tags at https://github.com/xpipe-io/xpipe/tags.

 Especially when starting out, it might be a good idea to start with easy tasks first. Here's a selection of suitable common tasks that are very easy to implement:
 
+### Interacting via the HTTP API

+You can create clients they communicate with the XPipe daemon via its HTTP API.
+To get started, see the [OpenAPI spec](/openapi.yaml).

 ### Implementing support for a new editor
 
 All code for handling external editors can be found [here](https://github.com/xpipe-io/xpipe/blob/master/app/src/main/java/io/xpipe/app/prefs/ExternalEditorType.java). There you will find plenty of working examples that you can use as a base for your own implementation.

-### Adding more file icons for specific types
-
-You can register file types [here](https://github.com/xpipe-io/xpipe/blob/master/app/src/main/resources/io/xpipe/app/resources/file_list.txt) and add the respective icons [here](https://github.com/xpipe-io/xpipe/tree/master/app/src/main/resources/io/xpipe/app/resources/browser_icons).
-
-The existing file list and icons are taken from the [vscode-icons](https://github.com/vscode-icons/vscode-icons) project. Due to limitations in the file definition list compatibility, some file types might not be listed by their proper extension and are therefore not being applied correctly even though the images and definitions exist already.

 ### Adding more context menu actions in the file browser
 
 In case you want to implement your own actions for certain file types in the file browser, you can easily do so. You can find most existing actions [here](https://github.com/xpipe-io/xpipe/tree/master/ext/base/src/main/java/io/xpipe/ext/base/browser) to get some inspiration.
