Git isn't GitHub
BitBucket
Heroku -git based webhosting

a repository is one project


~/.tmp $ mkdir gitintro
~/.tmp $ cd gitintro/
~/.tmp/gitintro $ git init .


global config file ~/.gitconfig
  git config --global user.name "John Doe"
  git config --global user.email johndoe@example.com
  git config --global color.ui auto

  git help config
  per-project ~/.git/config

edit a file
git status
git add actors
git status again

git commit -m "message"

git diff <filename or directory>

git log

Git commits are named as hashes to uniquely identify them and know that
no one has edited history

git checkout 
  change to a specific version of the project in the past, or a different
  branch

'detached HEAD' is OK, it just means you're not a the latest commit in a
branch

git checkout -b music
  to create and check out a new branch based on whatever the current commit
  is

# and then do some work, adding and commit

git checkout master
git merge music

a merge conflict means two people tried to edit the same thing in both
branches

git push
  share your work with others
git fetch
  copy down any remote commits
git pull
  fetch + merge

git help remote
git clone
  copy a remote repo to this computer

GUIs
  gitk
  Tower - really nice and friendly, very visual
  TortoiseGit
 GitHub for Windows is good
  there are many more
