Let's make a Hacker Blog™

summary: publish a github-pages enabled git repository, put some html in it and see it online. push to change the online version.

Git basics

a time-machine for (mostly text) files
stores the state of a directory at specific points in times (commits)
you can change stuff, delete files & generally do what you want. but if you want your old changes back, you can do that.
git setup (configure email, name and probably the editor aswell)

create an account on GitHub
create a repository called <your username>.github.io in the web interface (the book with the plus-icon on the upper right)
create a directory locally, make it a git repository too
```
  $ mkdir hackerblog
  $ cd hackerblog
  $ git init
```
create a file called index.html in that directory and make it look like this one
add the changes to git
```
  $ git add index.html
  $ git commit
```
push to github: git push -u origin master
wait a few minutes (probably 10 or so)
visit your blog at http://<your username>.github.io, you should see the html page that you just created
to preview your changes you can view the index.html file locally
