Instantiating Repositories

• Create a new repository by instantiating it through

  git init
  

• Copy an existing project by cloning the repository through

  git clone <url>

Central Repos

• To instantiate a central repository a --bare flag is required.

• Bare repositories don't allow file editing or committing changes.

• Create a bare repo with

  git init --bare project-name.git
