It's a blag!
All you should need to edit is in the content/ directory. There are two types of content:
Posts are in the content/posts directory.
A Post is an entry in the blog. It has a publish date, a title, and a body. You can look at one of the posts in the content/posts directory for an example of how to write a post.
The body of posts are processed through markdown, which allows you to easily specify things like links, italics, and bold.
For especially long posts, add the text
<!--fold-->
somewhere near the middle of the document. Content above the <!--fold--> tag will appear on the homepage, and readers will be able to continue reading by clicking a "Read More" link.
Pages are in the content/pages directory.
A page is a static piece of content, like the "About Me" page. It has a title, but no date.
Links are in content/links.yml. These are the links that will appear in the sidebar, including a link to the homepage, and various pages. Each link has a name, which is the text that will appear in the sidebar, and an href, which is the url it goes to. If a url starts with a /, that means it's on the local site. So if you want to link to a page stored in content/pages/my-cool-page.md, you would make a link with an href of /pages/my-cool-page.
All you should need is in the templates/ directory and the assets/ directory.
The stylesheet is in assets/sass/application.sass, and it uses a stylesheet language called Sass.
The templates are in the templates/ directory. They are written in a language called Haml. There are only a few important ones:
layout.hamlis the surrounding layout for the page.index.hamlis the homepage.post/header.hamlis shared between the home page and the post page - it displays a header with a date.post.hamldisplays a single post.page.hamldisplays a single page.
To run the server, you will need a ruby environment. I recommend installing via ry. Once you have that set up, open a terminal and run
$ bundle install
$ unicorn
Then you can go to http://localhost:8080/ in your browser to see the site.
It's simple enough, you should be able to figure it out :). Happy hacking.
