+- `${get_data["param"]}`
+- `${post_data["param"]}`
+
+Case-insensitive. If K/V pairs aren't used (but a string is provided, just without `=`) then
+it can be accessed through `${get_data}` / `${post_data}` (array element 0).
+
+### Arrays
+
+HTTP does arrays through concatenating multiple parameters with the same name. In our case, values
+are passed to a secondary array, and a reference to it is left for application use.
+
+```
+GET asdf/?a=1&a=2&a=3&b=1
+```
+
+will result in:
+
+```
+declare -A get_data=([b]="1" [a]="[array]" )
+```
+
+To get the value set out of an array, call `http_array <param_name> <output_name>`. For instance:
+
+```
+#!/bin/bash
+if ! http_array a array; then
+	echo "Not an array"
+	return
+fi
+
+for (( i=0; i<${#array[@]}; i++ )) {
+	echo "a[$i]=${array[i]}"
+}
+```
+

 Some of those (especially notORM) are also useful in a CLI environment, to help with migrations and
 other administrative tasks.
 
+## Invocation
+
 Utils integrate into HTTP.sh through calling the main script, with the utility name as the first
 parameter. So, for `meow.sh` the invocation would be `./http.sh meow`, or `./http.sh meow [params]`
 if the util takes any parameters.
@@ -19,6 +21,27 @@ Of note:
 
 A list of utilities can be obtained by calling `./http.sh utils`.
 
+## Creating your own
+
+Simply create a shell script in your namespace's util directory (that's usually `app/util/`), and
+mark it as executable. It has to have `.sh` as an extension, but shebang currently doesn't matter.
+
+It's recommended that if your util takes any positional parameters, it should check for $1 being
+set, and display a help message. An example of such script is listed below.
+
+```
+if [[ ! "$1" || "$1" == "help" ]]; then
+	echo "usage: $0 $HTTPSH_SCRIPTNAME <action>
+
+Action can be one of:
+  meow - Mrrrrrrrp!
+  help - This message."
+	exit 1
+fi
+
+# script continues here...
+```
+
 ## Built-in utils
 
 The following scripts are generic helpers shipped with HTTP.sh. We hope they'll come in handy.
