+**Usage**:

+qmk generate-compilation-database [-kb KEYBOARD] [-km KEYMAP]
+```
+
+Creates a `compile_commands.json` file.
+
+Does your IDE/editor use a language server but doesn't _quite_ find all the necessary include files? Do you hate red squigglies? Do you wish your editor could figure out `#include QMK_KEYBOARD_H`? You might need a [compilation database](https://clang.llvm.org/docs/JSONCompilationDatabase.html)! The qmk tool can build this for you.
+
+This command needs to know which keyboard and keymap to build. It uses the same configuration options as the `qmk compile` command: arguments, current directory, and config files.
+
+**Example:**
+
+```
+$ cd ~/qmk_firmware/keyboards/gh60/satan/keymaps/colemak
+$ qmk generate-compilation-database
+Ψ Making clean
+Ψ Gathering build instructions from make -n gh60/satan:colemak
+Ψ Found 50 compile commands
+Ψ Writing build database to /Users/you/src/qmk_firmware/compile_commands.json

-
-Wenn Du die globale CLI nicht verwenden möchtest, beinhaltet `qmk_firmware` auch eine lokale CLI. Du kannst sie hier finden: `qmk_firmware/bin/qmk`. Du kannst den `qmk`-Befehl aus irgendeinem Datei-Verzeichnis ausführen und es wird immer auf dieser Kopie von `qmk_firmware` arbeiten.

-## Einschränkungen der lokalen CLI
-
-Hier ein Vergleich mit der globalen CLI:
-
-* Die lokale CLI unterstützt kein `qmk setup` oder `qmk clone`.
-* Die lokale CLI arbeitet immer innerhalb der selben `qmk_firmware`-Verzeichnisstruktur, auch wenn Du mehrere Repositories geklont hast.
-* Die lokale CLI läuft nicht in einer virtualenv. Daher ist es möglich, dass Abhängigkeiten (dependencies) miteinander in Konflikt kommen/stehen.

 ### Adafruit BLE SPI Friend
 Currently The only bluetooth chipset supported by QMK is the Adafruit Bluefruit SPI Friend. It's a Nordic nRF5182 based chip running Adafruit's custom firmware. Data is transmitted via Adafruit's SDEP over Hardware SPI. The [Feather 32u4 Bluefruit LE](https://www.adafruit.com/product/2829) is supported as it's an AVR mcu connected via SPI to the Nordic BLE chip with Adafruit firmware. If Building a custom board with the SPI friend it would be easiest to just use the pin selection that the 32u4 feather uses but you can change the pins in the config.h options with the following defines:
-* #define AdafruitBleResetPin D4
-* #define AdafruitBleCSPin    B4
-* #define AdafruitBleIRQPin   E6
+* `#define ADAFRUIT_BLE_RST_PIN D4`
+* `#define ADAFRUIT_BLE_CS_PIN  B4`
+* `#define ADAFRUIT_BLE_IRQ_PIN E6`
 
 A Bluefruit UART friend can be converted to an SPI friend, however this [requires](https://github.com/qmk/qmk_firmware/issues/2274) some reflashing and soldering directly to the MDBT40 chip.

 ### Why am I seeing issues under Virtualbox?
 Certain versions of Virtualbox 5 appear to have an incompatibility with the Virtualbox extensions installed in the boxes in this Vagrantfile. If you encounter any issues with the /vagrant mount not succeeding, please upgrade your version of Virtualbox to at least 5.0.12. **Alternately, you can try running the following command:**
 
-```console
+```
 vagrant plugin install vagrant-vbguest
 ```
 
 ### How do I remove an existing environment?
 Finished with your environment? From anywhere inside the folder where you checked out this project, Execute:
 
-```console
+```
 vagrant destroy
 ```
 
 ### What if I want to use Docker directly?
 Want to benefit from the Vagrant workflow without a virtual machine? The Vagrantfile is configured to bypass running a virtual machine, and run the container directly. Execute the following when bringing up the environment to force the use of Docker:
-```console
+```
 vagrant up --provider=docker
 ```
 
 ### How do I access the virtual machine instead of the Docker container?
 Execute the following to bypass the `vagrant` user booting directly to the official qmk builder image:
 
-```console
+```
 vagrant ssh -c 'sudo -i'
 ```

 Then, redirect the `origin` remote to your own fork with:
 
-```sh
+```
 git remote set-url origin https://github.com/<your_username>/qmk_firmware.git

 Now that you have both remotes configured, you need to update the references for the upstream repository, which is QMK's, by running:
 
-```sh

 git fetch upstream

 At this point, resynchronize your branch to QMK's by running:
 
-```sh
+```
 git reset --hard upstream/master
 ```
 
 These steps will update the repository on your computer, but your GitHub fork will still be out of sync. To resynchronize your fork on GitHub, you need to push to your fork, instructing Git to override any remote changes that are not reflected in your local repository. To do this, run:
 
-```sh
+```
 git push --force-with-lease

+If you want to unit test a feature, take a look at some of the existing tests, for example those in the `quantum/sequencer/tests` folder. Then follow the steps below to create a similar structure.
 
 1. If it doesn't already exist, add a test subfolder to the folder containing the feature.
 2. Create a `testlist.mk` and a `rules.mk` file in that folder.
 3. Include those files from the root folder `testlist.mk`and `build_test.mk` respectively.
-4. Add a new name for your testgroup to the `testlist.mk` file. Each group defined there will be a separate executable. And that's how you can support mocking out different parts. Note that it's worth adding some common prefix, just like it's done for the serial_link tests. The reason for that is that the make command allows substring filtering, so this way you can easily run a subset of the tests.
