Setting configuration.
  git config --local user.name "Gonzo von Space"
  git config --local user.email gonzon.v.space@gmail.com

Create a new git repo in current dir and
add all files to it.
  git init
  git add .
  git commit -m "Initial commit."


Branching (example branch deva)
  git branch -a         # list all branches
  git branch deva
  git checkout deva

Given main.cpp that was changed and staged but
not committed yet, revert back to the way it
was before work started:
  git checkout main.cpp

Stuff to only do locally because it changes the commit hash.

Changing it after it's been pushed to a public repository will break the repository of anyone who has pulled the commits that are now gone. They are gone because changing a commit changes its hash and effectively creates a new different commit. 

Change the commit message for last commit.
  git commit --amend -m "This is the new message."

Given changes that were made since the last commit.
Add those changes to the last commit:
  git commit --amend



Files.

Configuration files:
  system       /etc/gitconfig
  global       ~/.gitconfig
  local        ./.git/config
Where local "." is the working directory of the
current git repo.

.gitignore
  Ignore all .* but not .gitignore itself.
    .*
    !.gitignore
