Raspberry Pi & github

Setting up access

 * The first step is to create a github account.  Then for those on the MagPi layout team, email the editor for permission to join the github organisation.
 * Since the Raspberry Pi does not have a great deal of processor power, it is better to use the command line tools to access github.  
 * Once you have a github account, on your Raspberry Pi type:
git config --global user.name "John Doe"
git config --global user.email J.Doe@machine.org

where the user name and email address should be replaced with your user name and email address. This is a one time configuration step. These settings are then stored in your ~/.gitconfig file.

 * The easiest way to use the command line tools is via an ssh key pair.  Type,
ssh-keygen

to create an ssh key pair and choose a secure password (upper and lower case letters, symbols and numbers without dictionary words). This is a one time configuration step, unless the password needs to be updated in the future.

 * Then go to your github account.  Select account preferences.  Then select "SSH Keys" from the left-hand menu.  Click on "Add SSH key" and add your public key (~/.ssh/id_rsa.pub).  This is a one time configuration step, unless the public key needs to be updated (for a password change) or another public key needs to be added.

Using github

 * At the start of an editing session (when you log into the Raspberry Pi), type:
ssh-agent
ssh-add
<pre>
then enter your password for the ssh key.  This step needs to be rebooted each time you log into the Raspberry Pi.

  * Then use the ssh read and write link from the github repository, e.g.:

git clone git@github.com:someorg/reponame.git 

this will create a folder called reponame.  The clone operation clones the repository to the local disk.
