I am working on webpage, and I need version tracking, so I'm uploading it to github.

Here is the underlying set up.
<https://developers.google.com/appengine/articles/wordpress>

Now that I have the base CMS ready to go, I need to get the base code uploaded before I start making changes.

```
lloydm@lloydm-E6320:~/Downloads/rtt/rtt-code$ pwd
/home/lloydm/Downloads/rtt/rtt-code
lloydm@lloydm-E6320:~/Downloads/rtt/rtt-code$ git status
# On branch master
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   wordpress/
nothing added to commit but untracked files present (use "git add" to track)
lloydm@lloydm-E6320:~/Downloads/rtt/rtt-code$ ls
app.yaml  cron.yaml  php.ini  wordpress
lloydm@lloydm-E6320:~/Downloads/rtt/rtt-code$ git add .
fatal: Not a git repository: wordpress/wp-content/plugins/../.git/modules/appengine-wordpress-plugin

```

I've never used github before, so I was just following the github website stuff. I have zero idea what this error means or how to prevent it. I can't find anything that I think is related to it.
