+  - In the newly exported folder, insert minecraft_server.jar and the bin folder from your .minecraft into the folder named '/jars'.  You'll need to provide your own bin folder with the jinput, lwjgl, lwjgl_util, and natives folder in it, as we cannot redistribute these. These files can be obtained by running the legacy Minecraft launcher with a jar for the correct version. If you only wish to decompile the client, the server jar is not required. Alternatively you can use setup.bat/sh in LTS to obtain these files and copy them over to your MCP folder.
   - Open /runtime/decompile.py with a text editor of your choice and remove line 15: ''commands.checkupdates()''
   - (Optional) If decompiling a mod, apply it to the relevant jar in the /jars folder.
   - Run the decompile.bat/sh file that has generated.
