+# page
+
+A static website generator for exactly 1 use case.
+
+"I have a bunch of gemini files that I want to serve as-is, but I also
+want to generate some HTML"
+
+## How to use
+
+1. Stand on the directory you want to turn into a page
+2. run page
+3. your output is in ../<directory_name>_html
+
+So for example:
+
+```
+$ pwd
+/home/rbdr/web/website
+$ page
+$ ls ..
+website/
+website_html/
+```
+
+## Front Matter
+
+You can add some optional front matter. We'll look at the two first lines that
+start with `---`
+
+The format is:
+
+```
+--- title: the title of the page
+--- description: a description
+```
+
+This only works if they are the first lines of the page.
+
+## Local Path Translation
+
+Links that end with `.gmi` will be replaced with `.html` unless they specifically start with `gemini:`
+
+## Layouts
+
+page expects a file called _layout.html in the root. It expects three placeholders:
+
+* {{ content }} the generated HTML from parsing the gemini text files.
+* {{ title }} the frontmatter title or an empty string.
+* {{ description }} the frontmatter description or an empty string.
+
+
+## Hidden folders
+
+Hidden folders get ignored, except for the .well-known folder.
+
+## What happens to files that aren't gemini?
+
+They're copied as-is.
