Most Squeak/Pharo Smalltalk development takes place these days in the context of either git itself or a git-like DVCS called Monticello. Use of git/monticello within the image directly mirrors use of git at the command-line in Unix. You use git/monticello to clone a remote repo, installing the code it contains into the live image. Because of other aspects of the Smalltalk design, this has an additional effect of being a bit like package installation - the code isn't just present, it's installed and ready to run. Unlike Unix, the lack of an explicit system-compilation step in Smalltalk means it's also ready to edit in-place, which means, if you've started some service instances, ready to edit live. It's very much like Docker or working with a Unix VM: you start from a known image, like a Docker FROM command or a Debian ISO, and install files/code/packages from there, using version control tools or not as you like.
