 # kivy - My first App
 ...to test and setup a build pipeline
 
-## Setup
+Obviously we use [kivy](https://kivy.org/) for this 'Hello World'. The app itself does nothing except displaying the words "Hello World!".
+But the exciting part of this git repo is the build pipeline
+
+Since a fe weeks forgejo/gitea have implemented github actions. And we use them to build the app.

+## Build Pipeline
-This is work in progress!
+### Bulldozer building
+There is a Github Action for building kivy apps for android using bulldozer. We mirrored the app to [https://backwesen.de/actions/gh-buildozer-action](https://backwesen.de/actions/gh-buildozer-action.git) and use it successfully for building our app.
+
+### Releasing
+Sadly gitea/forgejo does not support artifacts jet. So we have multiple different options for releasing our build binarys. Publishing them to other servers, put them in a new git repo or maybe there is a fancy way to attatch them to a release. For now we skipped this option and waiting for artifacts to become available.
+In the meantime we use  https://transfer.sh/ for uploading our files quick and dirty.
