 # Custom-Music-Discs-Minecraft-Datapack
 
 To use create a folder called: `music`
+
+Fill it with music in .ogg format and if you want distance to work, make sure its **mono** not **stereo**
+
+Then run:
+
+```
+run.bat
+```
+
+You should see 2 folders generated:
+- `cmd_dp`
+- `cmd_rp`
+
+1. Copy the `cmd_dp` to datapacks
+1. Copy the `cmd_rp` to resourcepack
+
+
+Internally the program creates an index of files, so if you add music into the `music` folder and rerun the program, updating the resourcepack and datapack will allow the old cds to work.
+
+Also the code randomlly generates .pngs for each audio file that is generated. The same music file will always generate the same color disc.
+
+**Limitations**, if you remove music the indexes will be messed up and old disks will no longer work.
+
+Todo add a gui interface
