+## Configuration
 
-Extensions are just executables in any language that output content. They can be system executables like `data` or custom extensions that you place in `.zs/`. To use an extensions simply reference it in your content like so:
+By default no configuration is required. Variables can be defined at the top of each content page using YAML front-matter as described in [Idealogy](#ideology). As your site gets more complex, you _may_ want to define a site-level configuration file. There are a couple of ways to do this:
 
-```markdown
+- Using command-line flags of `zs` itself, see `zs --help` for configuration options.
-Site last updated at {{{ date }}
+- Using environment variables such as `ZS_PRODUCTION=1`. These match the command-line flags above, are uppercase and prefixed with `ZS_`.
+- Using `zs -c/--config ...` to pass an explicit configuration file.
+- Placing a `.zs/config.yml` configuration file in your `.zs` directory.
+
+### Configuration file
+
+The basic structure of a configuration file looks like:
+
+```yaml
+---
+title: zs starter template
+description: A starter template for the Zen Static (zs) site generator
+keywords: zen, static, zs, starter, template, site, website, template, generator, ssg

+## Extensions (Markdown)
+
+`zs` supports content written in Markdown, `index.md` for example and uses the [Goldmark][goldmark] Markdown parser with a number of extensions enabled by default:
+
+- [anchor][anchor] -- Adds anchors (permalinks) next to all headers in a document.
+- [d2][d2] -- Adds support for [D2](https://d2lang.com/) diagrams.
+- [embed][embed] -- Adds support for rendering embeds from YouTube links.
+- [fences][fences] -- Support for pandoc-style fenced divs.
+- [highlighting][highlighting] -- Adds support for syntax highlighting of code.
+- [wikilink][wikilink] -- Adds support for [[wiki]]-style links to goldmark.

+For a full-list of default extensions enabled, see `zs --help` and the `-e/--extensions` flag.

+  Recent change: Made stylesheet and mimetype checks case insensitive.
+
+  http://livejs.com
+  http://livejs.com/license (MIT)  
+  @livejs
+
+  Include live.js#css to monitor css changes only.
+  Include live.js#js to monitor js changes only.
+  Include live.js#html to monitor html changes only.
+  Mix and match to monitor a preferred combination such as live.js#html,css  
+
+  By default, just include live.js to monitor all css, js and html changes.
+  
+  Live.js can also be loaded as a bookmarklet. It is best to only use it for CSS then,
+  as a page reload due to a change in html or css would not re-include the bookmarklet.
+  To monitor CSS and be notified that it has loaded, include it as: live.js#css,notify
