Make sure you have Docker Desktop or Docker Engine installed (don't forget to add your user to the docker group sudo usermod -aG docker $USER than logout and login again).
Then just ./build.sh and ./run.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 again ./run.sh until it works.
If it opens with tje screen showing garbage, run again until it works
