## One-time setup for F-Droid builds

1. Install *fdroidserver* by following the [installation instructions](https://f-droid.org/docs/Installing_the_Server_and_Repo_Tools).

2. [Sign up for a Gitlab account](https://gitlab.com/users/sign_up) and fork the [fdroiddata](https://gitlab.com/fdroid/fdroiddata) repository. 

3. Clone your fork of the *fdroiddata* repository.

## Release a beta version

1. Update versionCode and versionName in `app/k9mail/build.gradle`

### Create release on F-Droid

TODO

1. Fetch the latest changes from the *fdroiddata* repository.

2. Switch to a new branch in your copy of the *fdroiddata* repository.

3. Edit `metadata/com.fsck.k9.yml` to create a new entry for the version you want to release. Usually it's copy & paste of the previous entry and adjusting `versionName`, `versionCode`, and `commit` (use the tag name). Leave `CurrentVersion` and `CurrentVersionCode` unchanged. Those specify which version is the stable/recommended build.

4. Commit the changes. Message: "Update K-9 Mail to $newVersionName"

5. Run `fdroid build --latest com.fsck.k9` to build the project using F-Droid's toolchain. 

6. Push the changes to your fork of the *fdroiddata* repository.

7. Open a merge request on Gitlab. (The message from the server after the push in the previous step should contain a URL)

8. Select the *App update* template and fill it out.

9. Create merge request and the F-Droid team will do the rest.
