Last updated October 6, 2012.
This section provides an overview of how to use Git repositories on Drupal.org for both Drupal core and contributed projects.
Note: This screencast will walk you through Git on Drupal.org.
A user on Drupal.org will be granted commit access to a project only if they created the project or were granted permission by an administrator of the project.
To connect and commit to a Drupal.org Git repo, a user must clone the repository via SSH. For example:
git clone --recursive http://git.drupal.org/project/drupal.git would clone Drupal core.
This is a stub... the page will give the locations of the repositories, explain what replication means, and what the general (not tool-specific) process is to clone repos without giving command line commands or saying how to do it with different tools.
[This page should probably contain information about how to set up your Drupal.org account so you get credit for your work in commit logs, with a note to see your specific Git tool's "How to identify yourself to Git" directions for the HowTo.]
Sub-pages will explain how to achieve that with various tools: command line, Eclipse, etc.
