Install git

Linux (Ubuntu)

sudo apt-get install git-core

You may also want to install gitk and git gui

sudo apt-get install gitk
sudo apt-get install git-gui

These instructions are a useful guide to using git on Windows.
Install msysgit
- During the installation, make sure you add Windows Explorer integration, selecting both "Add Git Bash Here" and "Add Git GUI Here"
Once you've installed msysgit, you can right-click on any folder to open Git GUI (graphical user interface to git) or Git Bash (console interface to git)
Selecting "git bash" allows you to enter the git commands listed in these wiki pages

These steps are a one-time setup per-user per-machine.

The --global option stores the configuration settings in ~/.gitconfig in your home directory so that they apply to all repositories.

We require all commits in TubeTK to record valid author/committer name and email information. Use git config to introduce yourself to Git:

$ git config --global user.name "Your Name"
$ git config --global user.email "you@yourdomain.com"

Note that "Your Name" is your real name (e.g. "John Doe", not "jdoe"). While you're at it, optionally enable color output from Git commands:

$ git config --global color.ui auto

If less displays strange characters and no color, your LESS environment variable may already be set. You can override the less options with:

$ git config --global core.pager "less -FXRS"
