How to use git

1. when starting a new project type 
	git init
which intitiates the git repository
2. to add a file 
	git add $FILENAME
3. to check on the status type 
	git status
which should list all the files tracking and changes made since last commit
4. to commit your changes type
	git commit -m "a message goes here"
which commits your changes to the repository
5. to connect with github do the following
	git remote add origin $URL
which adds the remote origin to be the URL (case sensitive)
6. to commit those changes to github
	git push origin master
which pushes the changes to the origin (the github repository) master branch

How to use the same code over multiple machiens

1. go to the development directory and type
	git init

2. to clone the code type
	git clone https://www.github.com/$USERNAME/$project.git
(get this from the github page and click Fork)

3. this cloned repo has a default remote named "origin" which points to your fork not the master, change this name
	git remote add upstream https://www.github.com/$PROJECT_REP/$project_name.git

4. update our files
	git fetch upstream
which pulls new files but doesn't update ours

5. now suppose we go and update code and commit the changes
	git commit -m "blah"
	git push origin master
this pushes the changes to the master branch

6. now we go to another dev environment and want to work on the code, we update our files with git fetch and now
	git merge upstream/master
this merges your files with the master branch

BRANCHING AND STASHING
 git branch
lists all the branches you have available
 git checkout $BRANCHNAME
changes from current branch to branch name

NOTE if you haven't committed on current branch, you will need to stash
 git stash 

 git stash list (lists all the stashes)

pops the current stash off the stack (latest stash and deletes it)
 git stash pop

git remote deals with managing remote urls in git. This is useful for interacting with sites like bitbucket and github.

> git remote add [remote-name] $URL
adds a remote repository with the name remote-name at $URL. Other options exist to specify master, tagging, etc... see docs for details

> git remote rename <old> <new>
renames a remote with <old> to <new>. Straight forward

> git remote set-url [remote-name] $URL
changes the remote url of [remote-name]. By default this is often origin. Use to switch from ssh to https

> git remote [-v] show [remote-name]
displays information about the remotes set-up. -v is useful since it shows the actual remote urls


OTHER 
: to change the name of repository, go to the admin tab on the project homepage. Note you must update remote urls yourself!
