+server-status
+=============
+
+`mod_lua` version of the Apache httpd's mod_status using dynamic charts
+
+## What does it do? ##
+This script is an extended version of the known mod_status statistics page for httpd.
+It uses the simple Quokka Chart API to visualize many of the elements that are sometimes hard
+to properly diagnose using plain text information.
+
+Take a look at https://www.apache.org/server-status to see how it works.
+
+## Requirements ##
+* Apache httpd 2.4.6 or higher
+* mod_lua (with either Lua 5.1, 5.2 or LuaJIT)
+* mod_status loaded (for enabling traffic statistics)
+
+## Installing ##
+First, install mod_lua (you can enable this during configure time with --enable-lua)
+
+### Installing as a handler:
+To install it as a handler, add the following to your httpd.conf in the appropriate VirtualHost:
+
+ LuaMapHandler ^/server-status$ /path/to/server-status.lua
+
+### Installing as a web app:
+To install as a plain web-app, enable .lua scripts to be handled by mod_lua, by adding the following
+to your appropriate VirtualHost configuration:
+
+ AddHandler lua-script .lua
+
+Then just put the `.lua` script somewhere in your document root and visit the page.
+
+## Configuring
+There are a few options inside the Lua script that can be set to `true` or `false`:
+
+- `show_warning`: Whether or not to show a notice that this page is there on purpose.
+- `redact_ips`: Whether or not to replace the last few bits of every IP with 'x.x'
+- `show_modules`: Whether to show the list of loaded modules or not
+- `show_threads`: Whether to show thread details or not.
