@node Create a repository
@section Create a repository

A repository is a directory under source control,
normally your project you are working on.

Create an empty directory and @command{cd} into it:

@example
mkdir MY_PROJECT
cd MY_PROJECT
@end example

When you are inside the directory for the repository
issus the git command to initialise the repository:

@example
git init
@end example

This command creates a directory namend @file{.git}
inside the directory with all data git requires to
operate on the repository.

The next thing you want to do is to create a
@file{.gitignore} file, it is used to keep track
of with files that should be be included in the
repository, unless overruled with a forced staging.

A good base @file{.gitignore} content you probably
always want to use is:

@example
_/
# It is a good idea to allow the directory _ to
# contain temporary file you do not whant to stage.

.*
# Generally you probably do not want to include
# hidden files.

!.git*
# But you do generally want to include files
starting with .git, such as .gitignore.

\#*\#
*~
*.bak
# And you do not want to include backup files.
@end example

Git parses @file{.gitignore} with wildcards,
@code{#} for comments and @code{!} for inclusion
rather than exclusion, latter entires override
earlier entries.

When you have create you @file{.gitignore} you
are ready to stage it and make your first commit:

@example
git add .gitignore
git commit -n 'first commit'
@end example



@node Create an origin
@section Create an origin

It is a good idea to create a backup repostory,
so you do not lose your work on a disc failure,
filesystem corruption accidental removal.

You can such repostory for allowing collaboration
with a command repository that the collaborators
can all submit and fetch commits from.

This repository is customarly called `origin'.
And it is a bare repository, meaning that it
only hold the data in the @file{.git} directory
and cannot be used as the working directory.

@example
mkcd -p /srv/git/MY_REPOSITORY.git
cd /srv/git/MY_REPOSITORY.git
git init --bare

cd -  # Go back to your project respository
git remote add origin file:///srv/git/MY_REPOSITORY.git
git push -u orgin master  # master is the bransh you are working in
@end example

It is standard to append @file{.git} to the
end of the repository name when it is bare.

To submit your changes to origin you can now
use the command @command{git push}. To fetch
updates others have made, use the command
@command{git pull}.

@node What is Git?
@section What is Git?

Git is a version control system know for its lightning speed
and being distributed. A version control system is a system
for storing changes in a history tree and allow for multiple
people to work on the same project without the risk of the
code being too new to accept a submitted patch.

When you are working it is important to keep track of changes
so that you can find when edit step broke the system. But
version control also lets you create branches, these are
different versions of the same project being developed
concurrently which lets your team implement features in
parallel and merge them in into the mainline when stable.

And other important feature of version control that can
be used to tag releases of the code. If you have release
a program and is sent a bug report you may want to test
it one both the current version and the version the user
used.
