+# cfebs.srht.site
+
+A blog generator.
+
+## Usage
+
+Put posts in `./posts` as `.md` files.
+
+Add metadata to the head of each post file.
+
+Example:
+
+```
+Title:  My post
+Date:   2024-06-17T22:51:28-04:00
+---
+Now I'll start my _amazing_ markdown post
+```
+
+Run `python3 ./main.py` to regenerate the site.
+
+## Templates
+
+Also required are two template files: `index.html.tmpl`, `index.xml.tmpl`
+
+`index.html.tmpl` used for index and each post
+
+* Must contain a `${content}` variable where list of posts and post content will be replaced.
+
+`index.xml.tmpl` used for RSS
+
+* Can be used verbatim
+
+## TODO
+
+* Do not hard-code domain or posts location
+* Make templates examples that user has to move to locations
