-Basic Git Concepts
-------------------
-
-Making Changes
---------------
-Structure in the file system
-
-- one working tree per repository
-- `.git` folder is the *version database*
-- files/folders next to `.git` folder are the *working tree*
-

-
-Making Changes
---------------
-Checkout
-
-- populate the working tree with the commit you want to start working from
-
-image:../../img/git-checkout.png[]
-
-
-Making Changes
---------------
-Just start doing your changes
-
-- modify, add, delete files
-
-Tell Git which changes you intend to commit:
-
-	git add <file-name>
-
-EGit helps by auto-detecting changed files
-
-Committing Changes
-------------------
-
-	git commit
-
-- provide a commit message
-- commit represents a version of the complete repository
-- each commit is identified by a globally unique ID (SHA1)
-
-Commit Message
---------------
-
-- first line is header
-- separated by a blank line follows the body
-- last paragraph is for meta dat in the `key: value` format
-
-----
-First line is header, shall be shorter than 70 chars
-
-Separate the body from the header by an empty line. The commit message
-should describe why you are doing the change. That's what typically helps
-best to understand what the change is all about. The details of what you
-changed are visible from the file diffs.
-
-Body can be as many paragraphs as you want, shouldn't exceed width of 80
-chars. This helps command line tools to render it nicely. Paragraphs are
-separated by empty lines.
-
-Bug: NGP-123 is rendered as a hyperlink to jtrack
-----
-
-Making Changes
---------------
-Commit
-
-- create a new commit in the repository with the changes done in the working
-  tree
-

-
-Staging Changes - Git Index
----------------------------
-*Index* or *Staging Area* is where the next commit is prepared
-
-image:../../img/git-add-to-index.png[]
-
-Commits
--------
-- commit history
-	- B is successor of A
-	- C is successor of B
-
-image::../graph/git/bin/abc.png[align="center"]
-
-Branches
---------
-- branch is a named pointer to a commit, example: `master`
-- full name is `refs/heads/master`
-- the commit command moves the pointer
-
-image::../../img/git-commit-moves-branch.png[align="center"]
-
-Branches
---------
-
-- branch can also be moved "manually" to any commit
-
-	git reset
-
-image::../../img/git-reset-branch.png[]
-
-Branches
---------
-
-- what happens on next `git commit`?
-- `C` and `D` continue to exist but they are not in the history of the master
-  branch

-
-Branches
---------
-
-- usualy there are many branches in a Git repository
-- branches can also be deleted
