The document provides steps for creating a Git repository and making initial commits of files: 1. Create a Git account with your email and create a Git repository. 2. Initialize the Git repository in your local project folder with "git init" and make an initial commit of all files with "git add ." and "git commit -m 'first upload project'". 3. Make additional commits while adding and modifying files, including committing the deletion of a file, and merging branches.
