     - This defeats the purpose of RuneJS by implementing basic flows that any regular Java-based server would use. Think outside the box and really utilize ES6, TypeScript, Node, and RxJS! :)
 2. Additional/outside dependencies
     - Sometimes additional dependencies cannot be avoided, but we'd like to avoid them as much as possible. RuneJS intends to be simple and easy for anyone to pick up, without requiring the user to set up any databases or additional third party systems.

 ## Code Style
 
-We do have a few coding styles and lint rules we'd like all contributors to adhere to. **Please run the linter via `npm run lint` before submitting any Pull Requests**:
-
-- 4 space indentation 
-- Spaces between TS/ES6 import/export braces
-  - `import { this } from 'that';` instead of `import {this} from 'that';`
-- Semicolon line endings
-  - `let myVariable = true;` instead of only `let myVariable = true`
-- Single quotes instead of double quotes
-  - `let myString = 'hello world!';` instead of `let myString = "hello world";`
-  - `import { this } from 'that';` instead of `import { this } from "that";`
-- Avoid the `var` keyword
-  - `let myVariable;` instead of `var myVariable;`
-- Prefer `const` to `let`
-  - If a variable is never going to be modified, please declare it using `const` instead of `let`
-  - `const neverChanged = true;` instead of `let neverChanged = true;`
-- Add types to all method parameters and return types to all methods
-  - `public myMethod(firstParam: string, secondParam: number): void {` instead of `public myMethod(firstParam, secondParam) {`
-- Add `public`, `private`, or `protected` to every class variable or method
-  - `public myMethod(): void {` instead of `myMethod(): void {`
-  - `private myVar: number;` instead of `myVar: number;`
-- Use TypeScript getters/setters instead of specific getter/setter methods
-  - `public get myVar(): number` instead of `public getMyVar(): number`
-  - `public set myVar(myVar: number)` instead of `public setMyVar(myVar: number)`
+Code style (linting and formatting) are handled by [Biome](https://biomejs.dev/). It is recommended that you install [the Biome extension for your IDE](https://biomejs.dev/guides/editors/first-party-extensions/).
+
+Running `npm run fin` will perform all necessary checks (linting, formatting, typechecking and tests).

 There are two main benefits to this kind of design:
 
 - It serves as living documentation: from reading the `beforeEach` block you can clearly see how the prerequisite of "player is wearing a hat" is achieved
-- It allows for easy expansion of test cases: future developers can add further statements inside "when player is wearing a hat" if they want to make use of that setup

 * `npm run standalone` Launches all three servers concurrently without building

 * `npm run build` Builds the application

+* `npm run format` Runs Biome in formatting mode, use `format:fix` to autofix
