+# Battery Indicator
+
+The `BatteryIndicator.lua` script replaces the first icon on your homescreen with a battery level indicator that updates itself every time you click it. It makes use of the ligatures myMPD ships with and relies on your operating system reporting the battery level to a text file in `/sys`.
+
+- Determine where said file is: most likely `/sys/class/power_supply/[…]/capacity`
+- Create a new script and import `BatteryIndicator.lua`
+- Copy and paste the path to your `capacity` file into line 1
+- Make sure the name you gave to your new script is the same as the last attribute in the last line and save
+- Create a timer that runs the script regularly.

+# yt-dlp
+
+This script extracts the audio links and the associated metadata from an YouTube link and appends the result to the MPD queue. On playback MPD calls the script again to get the real streaming uri.
+
+The script was written by [sevmonster](https://github.com/sevmonster) - [Discussion](https://github.com/jcorporation/myMPD/discussions/1276).
+
+## Usage
+
+1. Install `yt-dlp`
+2. Import the script `yt-dlp`
+3. Start it from the main menu and copy the YouTube link in URI field.
