+# simpleconf.lua's Fine Manual
+
+read it
+## Usage
+### Loading config files
+
+Synopsis: `config = simpleconf.get_config([config_file, defaults])`
+
+`@config_file` (`string`)
+
+    Path of the file to load.
+
+`@defaults` (`table`)
+
+    A table containing your default settings.
+
+`config` (table)
+
+    Contains config values.
+
+Both values are optional.
+
+If the file and the defaults are present, it loads the defaults, then overwrites their values with those of the file.
+
+If the file is present, but not the defaults, it just loads the contents of the file.
+
+If the file isn't present, but the defaults are, it just loads the defaults, and you're using it wrong.
+
+If nothing is present, it returns an empty table.
+
+| File | Defaults | Result |
+| ---- | -------- | ------ |
+| 1 | 1 | file overwrites defaults |
+| 1 | 0 | just the file |
+| 0 | 1 | just the defaults |
+| 0 | 0 | nothing |
+
+## Config file format
+
+```
+bool = true
+number = 123
+string = the quick brown fox jumps over the lazy dog
+I am a comment!
+```
+(don't tell anyone, but it's all just a pattern nicked from Programming in Lua (page 82, 4th edition))
