Make sure you have docker installed.
Then just ./build.sh and ./run.sh, then you'll enter the container, then ./docker_init.sh
If this error happens:
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 130 (MIT-SHM)
Minor opcode of failed request: 3 (X_ShmPutImage)
Value in failed request: 0x13c
Serial number of failed request: 201
Current serial number in output stream: 202
run ./docker_init.sh until it works.
If it opens with tje screen showing garbage, run again until it works
