 # website.rb
 
-Ruby CGI scripts that I used to set up my website
\ No newline at end of file
+Ruby CGI scripts that I used to set up my website
+
+## What is included
+
+- listing.rb - generates a recursve listing of files at your preferred location
+- markdown.rb - processes markdown (partially) and converts it to HTML
+
+## How to apply this to your site
+
+- Drop all .rb files into your web directory root
+- Edit markdown.rb and point ROOT\_PATH to the full web directory root path
+- Edit listing.rb and point ROOT\_PATH to the full web directory root path and DIR\_PATH to the directory where markdown files are located (they have to be in adirectory under root!)
+- If you're using lighttpd:
+    - Install `mod_cgi` in your config file and add "listing.rb" as an index
+```
+server.modules += ("mod_cgi")
+index-file.names += ("listing.rb")
+cgi.assign = (
+    ".rb" => "/usr/bin/ruby"
+)
+```
+- If you're using apache:
+    - lmao idk
+    - just add CGI module, make it run ruby files and make listing.rb an index
+- If you're using NGINX:
+    - Install lighttpd and configure it the same way as above, but use a custom port for the server
+    - Add `listing.rb` as an index file to your preferred location
+    - Add a reverse proxy clause in NGINX config to proxy all .md and .rb requests to the lighttpd server
+```nginx
+        ...
+
+        # pass ruby files to lighttpd
+        location ~ \.rb {
+                proxy_pass http://127.0.0.1:6969;
+        }
+
+        # pass .md files as query parameters to markdown.rb
+        location ~ \.md {
+                proxy_pass http://127.0.0.1:6969/markdown.rb?docfile=$uri;
+        }
+
+        ...
+```
