+# Using percentCool
+## What is percentCool?
+percentCool (stylized with a lowercase p) is a programming language used to make websites.
+
+This is the documentation for percentCool.
+
+## How do I start?
+To start, you need to run the percentCool executable. You can do this by running `./percentCool` in your terminal.
+
+Running this will start a server on port 8000, and create the `www` and `sessions` directories.
+
+## How do I make a website?
+percentCool uses a file called `index.cool` to determine what to display on the website. This file needs to be created in the `www` directory.
+
+Once you have created this file, you can start writing percentCool code, but since you haven't learned how to do that yet, you can just write HTML.
+
+## How do I stop the server?
+To stop the server, press `Ctrl+C` in your terminal.
+
+# What are the data types?
+percentCool has 2 data types: `string` and `array`.
+
+## `string`
+A `string` is a sequence of characters. It is created by surrounding text with double quotes (`"`).
+
+You can also not use quotes at all, but then it will not parse spaces, meaning that `hello world` will be parsed as `hello`
+
+## `array`
+An `array` is a list of values. It is created by surrounding a list of values with `|` and each value with `,`.
+
+For example, `|1,2,3|` is an array with the strings `1`, `2`, and `3`.
+
+# Keywords
+Oh, this will be a long one.
+
+## `echo`
+`echo` is used to print text to the page. It takes one argument, which is the text to print.
+
+For example, `echo "Hello world!"` will print `Hello world!` to the page.
+
+## rndmax
+`rndmax` is used to set the maximum random number. It takes one argument, which is the maximum random number.
+
+If no argument is given, it will return the default maximum random number.
+
+For example, `rndmax 10` will set the maximum random number to 10.
+
+## random
+`random` is used to get a random number. It takes no arguments.
+
+For example, `random` will return a random number in the variable `_RANDOM`.
+
+## existing
+`existing` is used to check if a variable exists. It takes one argument, which is the variable to check.
+
+For example, `existing _RANDOM` will put `true` in the variable `_EXISTS` if `_RANDOM` exists, and `false` if it doesn't.
+
+## escape
+`escape` is used to escape a string for SQL. It takes one argument, which is the string to escape.
+
+Once escaped, the string can be used in SQL queries. It is recommended to use this when using user input in SQL queries.
+
+For example, `escape $name` will escape the string in the variable `name`
