 Characters are sent to the frontend and stored there when the character is created on the frontend.<br/>

+# Making a Story
+
+## Setting up
+
+You need these three files to make a story:
+
+- about.json
+
+- story.ha
+
+- characters.json
+
+## Filling out the files
+
+Inside about.json should be the following content:
+
+```
+{
+"title": "My Great Story",
+"description": "please read!"
+}
+```
+
+Change the title and description to whatever you would like.<br/>
+Inside story.ha should be the code for your story, see [the documentation on coding](/docs/SYNTAX.md) for help with this.<br/>
+Finally, inside characters.json should be a JSON formatted object containing all your characters.  See [the documentation on characters](/docs/CHARACTERS.md) for help with this file.<br/>
+
+## Making a story file
+
+A story file is just a zip file of these files, so zip up story.ha, characters.json and about.json into a zip file (make sure these are in the root of the zip file).
+
+## Playing your story
+
+To play your story, simply run cargo run \<your zip file\>

+# Syntax
+
+## Setup
+
+This is done in the about.json file,
+
+```
+{
+
+"title": "My Great Story",
+
+"description": "please read!"
+
+}
+```
+
+## Characters
+See [Character documentation](/docs/CHARACTER.md) for more info
+Referencing a character using the @, @NARRATOR is reserved for the Narrator.<br/>
+Customisation is done with @CHARACTER change \<feature\> \<feature name\><br/>
+Move a character with @CHARACTER to fr
+Outputting can be done with @CHARACTER says "string", see more at (outputs)[##outputs]
+
+> [!NOTE]
+> fr means front-right for instance.
+
+## Variables
+Currently only strings and integers are supported as variable types (booleans are planned).<br/>
+The interpreter can assume the data type so this doesn't need to be specified.<br/>
+To assign new variables (or overwrite existing ones):
+```
+$x = 1
+$an_integer = 3
+$y = "hello"
+$a_string = "world"
+```
+> [!NOTE]
+> Variable names can be as long as you want and can contain any characters except whitespaces
+
+To modify existing variables:
+```
+$x + 1              // Adds 1 to an integer x
+$x - 1              // Subtracts 1 from an integer x
+$y + " world"       // Appends " world" to the end of a string y
+```
+
+Other uses:
+```
+$x = choice "choice 1" {            // Assigns to x the choice made by the client
+...
+$x = input                          // Assigns to x the string input made by the client
+```
+
+## Outputs
+
+```
+@CHARACTER says "this string
+is multi-line
+and ends with a"
+
+$x = "hello world"
+@CHARACTER says $x
+
+$name = "deadvey"
+@CHARACTER says "hello $name"
+```
+> [!NOTE]
+> Strings only support double quotes now ("") and do not support having quotes within quotes.
+
+## Variables
+
+Variables are referenced with the \$, only integers will be supported.<br/>
+
+## Selection
+
+Condition based:
+
+```
+if condition {
+
+}
+
+elif condition {                    // Only gets checked if the if and all previous elif statements failed
+
+}
+
+else                                // Always passes if all previous if and elif statements failed
+
+}
+```
+> [!NOTE]
+> See [conditions](##conditions)
+
+Choice based:
+
+```
+choice "choice 1" {
+
+}
+
+or "choice 2" {
+
+}
+
+or "choice 3" {
+
+}
+```
+You can assign a variable to the result of a choice by doing the following:
+```
+$x = choice "choice 1" {
+...
+```
+
+## Positioning
+
+```
+@CHARACTER to position
+
+PAN position
+```
+
+## Conditions
+A condition works works like this:
+```
+$x == "hello"       // evaluates true only if x is "hello"
+$x > 1              // evaulates true if x is an integer and is more than 1
+$x < 1              // evaluates true if x is an integer and is less than 1
+$x >= 1             // evaluates true if x is an integer and is more than or equal to 1
+$x <= 1             // evaluates true if x is an integer and is less than or equal to 1
+
+```
+> [!NOTE]
+> == can be used for integers or strings whereas the rest can only be used with integers
+
+The order (variable operator value) is currently fixed and so must be layed out like this.
