 A plain and simple blog engine in Go. It serves Markdown files from a folder
 as HTML with a little bit of styling to make it all bearable and nice.
 
+## Setup
+
+To get started, you'll need a config like this:
+
+    host: http://localhost:8080
+    posts_path: ../posts
+    emails_path: emails.txt
+
+    meta:
+      title: My Awesome Blog
+      author: Me, the Author
+      email: [email protected]
+      links:
+        Git: https://github.com/me-the-author
+        YouTube: https://www.youtube.com/channel/me-the-author
+
+    smtp:
+      host: smtp.mail.com
+      port: 587
+      username: [email protected]
+      password: p4ssw0rd
+      sender: [email protected]
+
+You don't have to set up an SMTP server if you don't want; it'll still work
+without it, you'll just see some errors in the server logs.
+
+## Usage
+
+To launch your blog, use the CLI:
+
+    glean -conf prod.yml -port 80
+
+As long as your setup is good, it'll get going and you're in business!
