What are some of the issues that I should look out for when using Git?
One of the biggest issues of using Git is that it takes a lot of space when storing binary files. That includes any file that are not encoded in plain text such as images, office document formats and compiled programs.
This is mostly because the compression and hashing algorithms that Git uses to store objects heavily favor plain text files. It is possible to include binaries under version control, however, it is good practice to avoid using them with Git.
