+SYNOPSIS

+
Everyday Git With 20 Commands Or So
-===================================
-<<Individual Developer (Standalone)>> commands are essential for
-anybody who makes a commit, even for somebody who works alone.
+DESCRIPTION
+-----------
-If you work with other people, you will need commands listed in
-the <<Individual Developer (Participant)>> section as well.
+Git users can broadly be grouped into four categories for the purposes of
+describing here a small set of useful command for everyday Git.
-People who play the <<Integrator>> role need to learn some more
-commands in addition to the above.
+* <<STANDALONE,Individual Developer (Standalone)>> commands are essential
+ for anybody who makes a commit, even for somebody who works alone.
-<<Repository Administration>> commands are for system
-administrators who are responsible for the care and feeding
-of Git repositories.
+* If you work with other people, you will need commands listed in
+ the <<PARTICIPANT,Individual Developer (Participant)>> section as well.
+* People who play the <<INTEGRATOR,Integrator>> role need to learn some
+ more commands in addition to the above.
-Individual Developer (Standalone)[[Individual Developer (Standalone)]]
-----------------------------------------------------------------------
+* <<ADMINISTRATION,Repository Administration>> commands are for system
+ administrators who are responsible for the care and feeding
+ of Git repositories.
+
+
+Individual Developer (Standalone)[[STANDALONE]]
+-----------------------------------------------
A standalone individual developer does not exchange patches with
other people, and works alone in a single repository, using the
* linkgit:git-init[1] to create a new repository.
- * linkgit:git-show-branch[1] to see where you are.
-
* linkgit:git-log[1] to see what happened.
* linkgit:git-checkout[1] and linkgit:git-branch[1] to switch
* linkgit:git-rebase[1] to maintain topic branches.
- * linkgit:git-tag[1] to mark known point.
+ * linkgit:git-tag[1] to mark a known point.

modification will be caught if you do `git commit -a` later.

-<8> redo the commit undone in the previous step, using the message
-you originally wrote.

-<10> merge a topic branch into your master branch.
-<11> review commit logs; other forms to limit output can be
-combined and include `--max-count=10` (show 10 commits),
+<5> commit everything, as you have tested, with your sign-off.
+<6> look at all your changes including the previous commit.
+<7> amend the previous commit, adding all your new changes,
+using your original message.
+<8> switch to the master branch.
+<9> merge a topic branch into your master branch.
+<10> review commit logs; other forms to limit output can be

-Individual Developer (Participant)[[Individual Developer (Participant)]]
-------------------------------------------------------------------------
+Individual Developer (Participant)[[PARTICIPANT]]
+-------------------------------------------------
A developer working as a participant in a group project needs to
learn how to communicate with others, and uses these commands in
* linkgit:git-format-patch[1] to prepare e-mail submission, if
you adopt Linux kernel-style public forum workflow.
+ * linkgit:git-send-email[1] to send your e-mail submission without
+ corruption by your MUA.
+
+ * linkgit:git-request-pull[1] to create a summary of changes
+ for your upstream to pull.
+
+

+GitHub (www.github.com) to notify your upstream of your
+contribution.
-Integrator[[Integrator]]
+Integrator[[INTEGRATOR]]
------------------------
A fairly central person acting as the integrator in a group
them and publishes the result for others to use, using these
commands in addition to the ones needed by participants.
+This section can also be used by those who respond to `git
+request-pull` or pull-request on GitHub (www.github.com) to
+integrate the work of others into their history. An sub-area
+lieutenant for a repository will act both as a participant and
+as an integrator.
+
+
* linkgit:git-am[1] to apply patches e-mailed in from your
contributors.

-Repository Administration[[Repository Administration]]
-------------------------------------------------------
+Repository Administration[[ADMINISTRATION]]
+-------------------------------------------
A repository administrator uses the following tools to set up
and maintain access to the repository by developers.
* linkgit:git-shell[1] can be used as a 'restricted login shell'
for shared central repository users.
+ * linkgit:git-http-backend[1] provides a server side implementation
+ of Git-over-HTTP ("Smart http") allowing both fetch and push services.
+
+ * linkgit:gitweb[1] provides a web front-end to Git repositories,
+ which can be set-up using the linkgit:git-instaweb[1] script.
+
link:howto/update-hook-example.html[update hook howto] has a good
example of managing a shared central repository.
+In addition there are a number of other widely deployed hosting, browsing
+and reviewing solutions such as:
+
+ * gitolite, gerrit code review, cgit and others.
