The quickstart was worded confusingly - it said "from your project directory", which implied doing a `cd ..` down to the `projects` dir, which would cause `pelican content` to fail. In fact, you need to be in the `yoursite` directory, which is the directory that has the `content` directory in it.
The "Getting Started" docs became overly long and unwieldy over time.
This splits it into separate sections, including:
* Quickstart
* Installation
* Writing content
* Publish your site
