 ### Dependencies
 
-See `.gitlab-ci.yml`.
+See `.gitlab-ci.yml` or run `apt-get build-dep .`
 
 ### Build from git repo
 
-```
+```bash
 $ git clone https://source.puri.sm/Librem5/squeekboard.git
 $ cd squeekboard
-$ mkdir ../build
-$ meson ../build/
-$ cd ../build
-$ ninja test
-$ ninja install
+$ mkdir _build
+$ meson _build/
+$ cd _build
+$ ninja
 ```
 
+To run tests use `ninja test`. To install squeekboard run `ninja install`.
+
 Running
 -------
 
-```
+```bash
 $ phoc # if no compatible Wayland compositor is running yet
 $ cd ../build/
 $ src/squeekboard
 ```
 
+Squeekboard honors the gnome "screen-keyboard-enabled" setting. Either enable this through gnome-settings under accessibility or run:
+
+```bash
+$ gsettings set org.gnome.desktop.a11y.applications screen-keyboard-enabled true
+```
+
+To make the keyboard show you can use either an application that does so automatically, like a text editor or `python3 ./tests/entry.py`, or you can manually trigger it with:
+
+```bash
+busctl call --user sm.puri.OSK0 /sm/puri/OSK0 sm.puri.OSK0 SetVisible b true
+```

-**Get one of the existing keyboard layouts**
+So at least I will try to start writing a short how-to here and edit this post as I find the time. Hope this helps a bit - comments and corrections [welcome](https://source.puri.sm/Librem5/squeekboard/-/merge_requests/)
 
-* You can get one of the keyboards from the squeekboard git repository : [https://source.puri.sm/Librem5/squeekboard ](https://source.puri.sm/Librem5/squeekboard)
-* The keyboard layouts are located in the subdirectory `data/keyboard/` in the `.yaml` files
+## Creating a new layout
+
+Creating a layout is easy. You don't need to recompile things, just edit and test. It's easiest to start with an existing layout.
+
+### Get one of the existing keyboard layouts
+
+* You can get one of the keyboards from the squeekboard git repository : [https://source.puri.sm/Librem5/squeekboard](https://source.puri.sm/Librem5/squeekboard)
+* The keyboard layouts are located in the subdirectory [`data/keyboards/`](https://source.puri.sm/Librem5/squeekboard/-/tree/master/data/keyboards) in the `.yaml` files
 * Take a look and try to understand them :slight_smile:
 
-**Fork your own copy of squeekboard**
+
+### Creating the keyboard layout
+
+* To be written: For the time being, take a look at [Using non-latin language on Librem 5](https://forums.puri.sm/t/using-non-latin-language-on-librem-5/7103/5)
+* The correct name of the .yaml file can be found with the command 
+
+```
+gsettings get org.gnome.desktop.input-sources sources
+```
+
+The output should be something like this: `[('xkb', 'us'), ('xkb', 'de')]`
+So for example “de.yaml” would be the correct name for the German keyboard layout.
+
+If the name of your layout is not translated correctly in the list, you can fix it by adding it and recompiling Squeekboard.
+
+### Testing the layout
+
+Copy your yaml file to `~/.local/share/squeekboard/keyboards/` for testing purposes. From there it should get picked up by squeekboard automatically.
+
+You can also use the `test_layout` tool from the -devel package to check it for errors:
+
+```
+# squeekboard_test_layout ./mylayout.yaml
+Test result: OK
+```
+
+## Contributing your changes
+
+If you want to share your layout with the world, the best way is to submit it to the Squeekboard project. The workflow is similar to any other Gitlab-based project.
+
+Above all, your layout should be working, be tested, not break anything, and make sense.
+
+### Fork your own copy of squeekboard
 
 * Best way would be to start with a fork of the squeekboard repository: Create a user account at https://source.puri.sm/, go the the squeekboard git repository, press “Fork” in the web interface. You can find further instructions [here](https://docs.gitlab.com/ee/user/project/repository/forking_workflow.html#creating-a-fork).
 * Clone your fork locally with `git clone` and use the uri of your forked repo there
 
-**Workflow to edit your keyboard and get it merged**
+### Edit your keyboard and get it merged
 
-* A generic guide how the workflow to contribute works, can be found at https://developer.puri.sm/Librem5/Contact/Contributing.html
+* It may be useful to check out the [generic guide how the workflow to contribute works](https://developer.puri.sm/Librem5/Contact/Contributing.html)
 * Create a branch: Name it “keyboard-layout-mylanguage” or whatever
 * Checkout your branch, edit your keyboard layout and commit your changes
+* Your layout **must** be correctly named, and in `data/keyboards/`.
+* Your layout **must** pass the `test_layout` tool with zero problems.
+* Your translation **must** be correctly named, and in `data/langs/`.
+* Your layout or translation **must** be added to automatic tests. **Don’t forget to add it** to `src/resources.rs` and the layout to `tests/meson.build` (that’s for me, because I always forget it).
+
+### Get it merged
+
+It's always recommended to **compile and run** squeekboard before submitting your changes. This serves as a test that all is working. See instructions in the [compiling section](#compiling-and-running-squeekboard).
+
 * Push the local changes (to the branch of your fork of squeekboard)
 * Create a merge request for the branch to get your changes merged to the official squeekboard git repository
 
-**Compile squeekboard**
+If your changes pass automated tests (CI), then the merge request will be reviewed by the maintainers, and you might be asked to change a thing or two.
 
-* Follow the instructions found in “Building” section of the squeekboard’s README: Running squeekboard: [https://source.puri.sm/Librem5/squeekboard/blob/master/README.md#building ](https://source.puri.sm/Librem5/squeekboard/blob/master/README.md#building)
+## Compiling and running Squeekboard
 
-**Running squeekboard**
+If you want your change to become part of official Squeekboard, or if you want to add a translation of your layout name, you will have to recompile Squeekboard and test your changes there.
 
-* Follow these instructions to run squeekboard: [https://source.puri.sm/Librem5/squeekboard/blob/master/README.md#running ](https://source.puri.sm/Librem5/squeekboard/blob/master/README.md#running)

 * Additionally take a look at the contribution document for [testing info](HACKING.md#testing)
-* You can either test it locally on your Linux system or use the [QEMU Librem 5 image ](https://developer.puri.sm/Librem5/Development_Environment/Boards/emulators.html)
+* You can either test it locally on your Linux system or use the [QEMU Librem 5 image](https://developer.puri.sm/Librem5/Development_Environment/Boards/emulators.html)
 * To test squeekboard locally, you need phoc. Either compile that from the sources as well or use the CI repository ci.puri.sm for Debian based systems:
   `deb [arch=amd64] http://ci.puri.sm/ scratch librem5`
 
 Squeekboard can be installed from there as a Debian package, too (that’s what I often do). But beware - there be dragons! You could bork your system with these packages and you should probably disable this repository again after installing what you need - these packages are not meant for production systems (or so I heard :wink: )

-**Creating the keyboard layout**
-
-* To be written: For the time being, take a look at [Using non-latin language on Librem 5 ](https://forums.puri.sm/t/using-non-latin-language-on-librem-5/7103/5)
-* The correct name of the .yaml file can be found with the command `gsettings get org.gnome.desktop.input-sources sources`
-
-The output should be something like this: `[('xkb', 'us'), ('xkb', 'de')]`
-So f.ex. “de.yaml” would be the correct name for the German keyboard layout.
-* The translations for the keyboard layout names in the different languages can be found at `data/langs/`
-* Don’t forget to add your newly created layout or translation to `src/resources.rs` and the layout to `tests/meson.build` (that’s for me, because I always forget it)
-
-**Testing the layout**
-
-* Copy your yaml file to `~/.local/share/squeekboard/keyboards/` for testing purposes. From there it should get picked up by squeekboard
-* To test the translations in `data/langs/` , you have to compile squeekboard
