 WARNING: **The ue4-docker maintainers do not provide support for building and running Linux containers under Windows**, due to the various technical limitations of the Hyper-V and WSL2 backends for Docker Desktop (see https://github.com/adamrehn/ue4-docker/issues/205[this issue] for details of these limitations).
 This functionality is still present in ue4-docker for those who choose to use it, but users are solely responsible for troubleshooting any issues they encounter when doing so.
