-A small script to allow the Keychron K2 Keyboard to boot up with function keys enabled by default.
+# Enable Function Keys On The Keychron K2 Mechanical Keyboard Under Linux
+
+
+Below, you'll find the steps required to create a systemd command that will run at boot to diable the media keys and restor f1-f12 functionality.
+
+## Step 1
+
+Open a terminal window and enter the following command:
+
+`sudo nano /etc/systemd/system/keychron.service`
+
+## Step 2
+
+Paste the following into the window:
+
+```[Unit]
+Description=The command to make the Keychron K2 work
+
+[Service]
+Type=oneshot
+ExecStart=echo 0 | sudo tee /sys/module/hid_apple/parameters/fnmode
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Press `ctrl+o` and then `ctrl-x` to exit.
+
+## Step 3
+
+In the terminal, type the following:
+
+`systemctl enable keychron`
+
+## Step 4
+
+That's it! A reboot, and you'll see that the function keys have been re-enabled.
+
+## Closing Remarks
+
+If you want to simply drag/drop the file that you create manually in the steps provided, I have it under the scripts folder in this repo. Download it and drop it in `/etc/systemd/system/`, doing Step 3 at the end.
