 ## Requirements
 
- - **[Haxe compiler](https://haxe.org)**: you need an up-to-date and working Haxe install  to build LDtk.
- - **[NPM](https://nodejs.org/en/download/)**: this package manager is used for various install and packaging scripts. It is packaged with NodeJS.

-## Installing required stuff
-
- - Open a command line **in the `ldtk` root dir**,
- - Install required Haxe libs:
- ```
- haxe setup.hxml
- ```
- - Install Electron locally and other dependencies through NPM (**IMPORTANT**: you need to be in the `app` dir):
- ```
- cd app
- npm i
- ```
+## Compiling another branch
 
-## Compiling *master* branch
+If you want to try a future version of LDtk, you can checkout branches named `dev-x.y.z` where x.y.z is version number e.g. `dev-1.2.3`
 
-First, from the root of the repo, build the electron **Main**:
+**IMPORTANT**:
+- these *dev* branches might be unstables, or even broken. Therefore, it's not recommended to use, unless you plan to add or fix something on LDtk.
+- because *dev* branches might change quickly, you will need to update haxelibs often.
+- you will need to switch the *LDtk haxe API* to the **same**/**nearest** branch as LDtk repo. (adapt the branch name below accordingly):
 
+edit this line in setup.hxml
 ```
-haxe main.debug.hxml
+--cmd haxelib git ldtk-haxe-api https://github.com/deepnight/ldtk-haxe-api.git dev-1.2.1 --always
 ```
 
-This should create a `app/assets/main.js` file.
-
-Then, build the electron **Renderer**:
-
+- Run this in a terminal in the root folder of the repo
 ```
-haxe renderer.debug.hxml
+haxe setup.hxml
 ```
 
-This should create `app/assets/js/renderer.js`.
+In vscode to get intilisense make sure to change the haxe configuration to `renderer.debug.hxml`
 
-## Compiling another branch
+If you make changes to scss remember to use a compiler such as sass or a vscode extension to compile it to css
 
-If you want to try a future version of LDtk, you can checkout branches named `dev-x.y.z` where x.y.z is version number.
