+# rikidown
+
+A Rust-based wiki with markdown.
+
+Simply write your wiki pages in Markdown, commit to a git repo and push.
+rikidown will refresh its git repo, then render your markdown pages inside of a template.
+
+## How does it work
+
+GET /README.md HTTP/1.1
+
+When rikidown recieves a GET request for a markdown page, it renders it using markdown-rs.
+
+rikidown uses rouille to start the http server, and clap to configure arguments.
+The arguments supported include:
+
+- --git-repo the URL of the git repo to load
+- --listen address to listen on, in the form of 0.0.0.0:8080
