 ## Building the app

-The application doesn't use Gradle and it might be hard to use some features of
-Android Studio.
-
-Fortunately, there's not many dependencies:
- OpenJDK 8
+The application uses Gradle and can be used with Android Studio, but using
+Android Studio is not required. The build dependencies are:
+- OpenJDK 17
 - Android SDK: build tools (minimum `28.0.1`), platform `30`
- Make sure to have the `$ANDROID_HOME` environment variable set.
+
+Python 3 is required to update generated files but not to build the app.
+
+For Android Studio users, no more setup is needed.

 For Nix users, the right environment can be obtained with `nix-shell ./shell.nix`.
 Instructions to install Nix are [here](https://nixos.wiki/wiki/Nix_Installation_Guide).

+If you don't use Android Studio or Nix, you have to inform Gradle about the
+location of your Android SDK by either:
+- Setting the `ANDROID_HOME` environment variable to point to the android sdk or
+- Creating the file `local.properties` and writing
+  `sdk.dir=<location_of_android_home>` into it.
+
 Building the debug apk:

 ```sh
-make
+./gradlew assembleDebug
 ```

-If the build succeed, the debug apk is located in `_build/juloo.keyboard2.debug.apk`.
-
-## Using the local debug.keystore on the Github CI actions
-
-It's possible to save the local debug.keystore into a github secret, so the same keystore is utilized to build the debug apk in the CI github actions.
-Doing this, they wil have the same signature, thus the debug apk can be updated without having to uninstall it first.
-
-After you sucessfully run `make`, (thus a debug.keystore exists) you can use this second command to generate a base64 stringified version of it
-
-```sh
-cd _build
-gpg -c --armor --pinentry-mode loopback --passphrase debug0 --yes "debug.keystore"
-```
-
-A file will be generated inside the local `_build/` folder, called `debug.keystore.asc`
-
-You can copy the content of this file, and with that, paste it into a new github secret in your repo settings.
-
-The secret must be named `DEBUG_KEYSTORE`
+If the build succeeds, the debug apk is located in `build/outputs/apk/debug/app-debug.apk`.

 ## Debugging on your phone

 First [Enable adb debugging on your device](https://developer.android.com/studio/command-line/adb#Enabling).

+If you use Android Studio, this process will be automatic and you don't have to

+## Specifying a debug signing certificate on Github Actions
+
+It's possible to specify the signing certificate that the automated build
+should use.
+After you successfully run `./gradlew asssembleDebug`, (thus a debug.keystore
