+Git has a messy learning curve. This file is an attempt to serve as a quick
+reference for basic tasks while you get up to speed.
+
+------------------------
+
+git checkout [-f] (branch)
+
+Switch your local repository to be at the most recent commit of (branch). 
+Including -f will discard changes made in the working directory.
+
+
+git status [-uall | -uno]
+
+Shows all changed files in your local repository and also a list of the ones
+you have staged for commit.
+Including -uall will also show you all untracked files in all subdirectories.
+Including -uno will show you _no_ untracked files.
+
+
+git log [-NUM]
+git log <commit1> <commit2>
+git log [--pretty=one]
+git log (branch)
+
+For a full explanation of all the arguments you can pass to 'log', please see
+the manual; there are a lot and these are just a few of the common ones. For 
+our purposes, git log will show you all the commits according to criteria 
+you specify:
+
+-NUM: The last NUM commits in this branch
+<commit1> <commit2>: all commits between commit1 and commit2
+-pretty=one: format output as a single line for each entry
+(branch): show the commits from (branch) instead of the current one
+
+
+git add (filename)
+
+Adds the changes you've made in (filename) to the pre-commit staging area.
+(also referred to as the 'index')
+
+
+git commit [-a] [-m "text"]
+
+Commits all staged changes (in the index) to this branch in your local repo
+from your current position.
+Including -a will 'git add' all eligible files before doing so.
+Including -m will use "text" as the commit message instead of opening an
+editor window for you to create one.
+
+
+git push [--all] [-u origin (branch)]
+
+Sends all your commits for the current branch to the centralized repo.
+Including --all will send the commits for _all_ branches.
+Specifying -u is only needed the first time you push (branch) that you
+created; it establishes the connection between local and remote for that
+branch.
+
+
+git reset [--hard] (filename)
+
+Without any parameters, unstages the changes for (filename) from the index;
+does not change the working tree. This is the equivalent of the command 
+git reset --mixed (filename); git reset --soft (filename) has no effect.
+
+With --hard, unstages (filename) from the index and reverts (filename) in
+the working tree to the most recent commit.
+
+*** WARNING *** --hard _will_ throw away your changes.
+
+
+[DSR: I'm hesitant about including this command because you can trash stuff
+with it. But at the same time, for people who are adapting to a commit not
+also automatically being a send, it's nice for them to know how to undo one in
+case they do something wrong. thoughts?]
+
+git reset [--soft | --mixed | --hard] HEAD~1
+
+*** WARNING *** Never, EVER do this to a commit that you have already pushed;
+you will be rewriting history on other people's machines and this will
+generally turn out very poorly.
+
+With --soft, undoes the most recent 'git commit' action, but leaves the 
+changes in the index and in the working directory.
+
+With --mixed, does everything --soft does but also unstages the changes from
+the index. If you don't specify one of the three, reset will assume this.
+
+With --hard, does everything --mixed does but also reverts the working tree to
+the prior commit. 
+
+*** WARNING *** --hard will effectively delete a commit and "lose" the changes.
+
+
+git fetch [-a]
+
+Retrieve commits from the remote repository to your machine.
+Including -a will get commits for all branches.
+
+
+git pull
+
+Incorporate any fetched commits for the current branch into your repository
+and update your position accordingly.
+
+
+git merge (branch) [--no-commit]
+
+Merges all the changes from (branch) since it last diverged from a common
+ancestor into your current branch.
+
+With --no-commit, does not automatically create a merge entry in the log but
+leaves all the merged files in your working directory; to complete the merge
+you must commit them manually later (likely after you have edited them).
