### What has been done
- Integrated the project with [GitHub Actions](https://github.com/features/actions) (closes #25)

### External dependencies
- https://github.com/vgaidarji/docker-android
- https://github.com/vgaidarji/android-github-actions

### TODO
- [x] Find time to finish this PR 🙉 
- [x] Configure environment variables
- [x] Find a way to provide build numbers in builds from Actions (nr. of commits?)
GitHub Actions don't have build numbers exposed. Calculating number of commits between tags or master/feature branches - possible; using timestamps of commits from branches is also possible. Will take care of it later ¯\\_(ツ)_/¯ 
- [x] Finish documentation
- [x] Describe GitHub Actions in table with other CI's

### Notes
- Bitrise build is broken for some reason (infra issue, nothing changed in the project since last successful build), see #27
