 ## Usage
 
 ### Installation
-Clone the repository
+The easiest way to get started with Lumaca is to use the Go package manager:
+
+```sh
+go install github.com/jmcharter/lumaca@latest
+```
+
+Alternatively, you can clone this repo and generate your own binary.
+
+### Get Started
+
+Once it's installed, create a new directory for your blog and run the `init` command:
+
+```sh
+mkdir MyBlog
+cd MyBlog
+lumaca init --author "John Doe" --title "MyBlog"
+```
+
+This will create a config file for you, which you can customize if you wish. It will also generate all of the boilerplate and template you need to get going.
+
+To create your first blog post, use the `new` command.
+
+```sh
+lumaca new --title "My First Post"
+```
+
+A markdown file with some Frontmatter will be generated in your `Posts` directory (`content/posts`). Edit as appropriate, and when you're finished writing your post, you can run `build` to generate the html.
+
+```sh
+lumaca build
+```
+
+And if you'd like to see how it looks locally before deploying somewhere, you can run `serve`.
+
+```sh
+lumaca serve
+```
