Project assignments For now, make sure you can: ● Prepare virtual machine ○ ○ Install Virtual. Box Import class VM into Virtual. Box ● Prepare gitlab ○ ○ ASAP: Log in to UMD Git. Lab instance using UMD CAS. You need to do this to be granted access to your gitlab repository that we will provide you with. Create ssh keypair on the VM Provide public key to gitlab Clone student repository onto vm ● Detailed instructions: Bootstrap process- CMSC 417
