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 Repositories

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

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

  • Create a bare repository with:

    git init --bare project-name.git

Instantiate workflow with clone

  1. Create a project in your user namespace.
  2. Create a 'Workspace' directory in your home directory.
  3. Clone the 'training-examples' project.
mkdir ~/workspace
cd ~/workspace

git clone<username>/training-examples.git
cd training-examples
