1. Add a new task in Cmder settings
   • Win + Alt + P to open settings, then go to Startup > Tasks.
   • Then hit the + symbol on the bottom to create a new task
2. Rename the task to Babun (or whatever you want)
3. Add this command in Task Parameters:
   • /icon "%userprofile%\.babun\cygwin\bin\mintty.exe" /dir "%userprofile%"
4. Add this command in Commands:
   • %userprofile%\.babun\cygwin\bin\mintty.exe -o Transparency=0 /bin/env CHERE_INVOKING=1 /bin/zsh.exe

This is what it should look like when you are done:

You're now ready to use Babun in Cmder
