When you first clone this repository, a sample project called "blog" is included. If you want your own project to be called "blog", you could move all the example posts somewhere else for reference or delete them and fill the posts folder with your own posts. Or you could rename the sample project and start a new one.
To create a new project, create a directory with the following structure:
/
assets/
data/
authors.yml
categories.yml
pages/
posts/
config.yml
Details on the relevant elements can be found elsewhere in the documentation, but here is a summary:
assets/: A directory for all public assets you want to include in your site.data/: Information about authors and categories for your site.pages/: A directory for your pages, organized however you want.posts/: A directory for your posts, organized however you want.config.yml: The configuration file for your site.
