"New presentation" instructions are not clear enough

[nmusolino]

The steps for creating a new presentation are, in their entirety:

• Create a new directory
• Place required markup files and any custom css and image files here
• Copy the example_presentation/presentation.cfg to here and change the filenames and paths as required

Instead of saying "Place required markup files ... here", these instructions should say what files should be placed here.

Additionally, I naively tried to use the avalanche theme by running landslide --theme=avalanche presentation.rst. This failed to work even though avalanche was installed in my Python site-packages folder. Is using the --theme option to lanslide encouraged, required, or not supported?
