 **PIKOlang *(Porn Is Kinky Obviously)*** is a simple, interpreted, esoteric 2-Dimensional programming language. To write **PIKOlang *(Professionally Interpreted Kernel Operations)***, you need to write a program in a 2D grid, where each cell is a command. The program in **PIKOlang *(Probably Incomplete Kotlin Object)*** is executed by a cursor that moves around the grid, executing the commands it encounters. You can either execute the entire **PIKOlang *(Python Is Kinda Overrated)*** program at once or step through it one command at a time.
 
+## Online playground

+You can try out the language at the [Online Playground](https://matronator.github.com/PIKOlang).
+
 ## Syntax
 
 The program starts with `#` symbol placed anywhere on the grid. The grid can be arbitrarily large. The cursor always starts facing right and moves in the direction it is facing, executing the commands in order as they are encountered (the cursor moves over them).

+## Pointers
+
+The program starts with `#` symbol placed anywhere on the grid. The grid can be arbitrarily large. The pointer always starts facing right and moves in the direction it is facing, executing the commands in order as they are encountered (the pointer moves over them). Currently, there can only be one pointer in the program, but in the future I want to implement concurrency with multiple pointers.

 ## Memory
 
-The language has two memory registers and one output register:
+Each pointer has two memory registers and one output register:
 
 - **Register** - A single integer value that can be modified by the program.
 - **String Register** - An array of characters that can be modified by the program. When in *String Mode™️*, any characters and symbols the pointer moves over are added to the string register.
 - **Output Register** - Either a number or a string that is printed when the program exits. If the output register receives a string, the whole register gets converted to a string and any further number added will be appended as a string.
