 The project is using [`clang-format`](https://clang.llvm.org/docs/ClangFormat.html) to format most files. You need to run `bash ./clang_format.sh` before your PR for a successful pipeline.
 
 Furthermore, there is an `utf-8` and `LF` checker to fix file formats. Additionally, some spellchecks run inside the [pipeline](.github/workflows/static_checks.yml).

+## Release library
+
+As a maintainer you are able to create a new release.
+1. Go to  [create new release](https://github.com/Geequlim/ECMAScript/releases/new)
+2. Next you should ``Choose a tag`` and create a new one in the format `v0.0.0`
+3. Select target ``master``
+4. Click ``Generate release notes``
+5. (Optional) You can edit the generated release notes
+6. Add a release title in the format ``[Godot_Version]-[Tag]-alpha-[Year][Month][Day]`` as an example ``4.1-v0.0.17-alpha-20231003``
+7. Press ``Publish release``

+# Use GDScript in TypeScript
+
+This example shows how to use a class written in GDScript in another TS class.
+
+For the `TypeScript` examples, all `.ts` files will be compiled as `.mjs` to the folder `scripts/generated/**`.
+
+## 1. Create the GDScript file
+
+First we create a simple class with GDScript inside a new file `scripts/gd/GDTest.gd`:
+
+````gdscript title="GDTest.gd"
+extends Node
+
+func _ready():
+	pass
+
+func print_in_gd_test():
+	print("gd_test")
+
+````
+
+## 2. Create a declaration (*.d.ts) for GDScript (only TypeScript)
+
+For proper TypeScript support we need to add a ``gdtest.d.ts`` file:
+
+````ts title="gdtest.d.ts"
+declare module "res://scripts/gd/GDTest.gd" {
+  class GDTest {
+    call(func: "print_in_gd_test"): void;
+
+    static new() {
+      return this;
+    }
+  }
+  export = GDTest;
+}
+````
+
+## 3. Use the class inside your TS file
+
+In the end we need to call the ``GDTest.gd`` from another `(.mjs|.ts)` file, like `main.(mjs|ts)`:
+
+=== "JavaScript"
+    ````ts title="main.mjs"
+    import GDTest from "res://scripts/gd/GDTest.gd";
+    
+    export default class Main extends godot.Node {
+        _ready() {
+            const gdTest = GDTest.new();
+            gdTest.call("print_in_gd_test");
+        }
+    }
+    
+    ````
+=== "TypeScript"
+    ````ts title="main.ts"
+    import GDTest from "res://scripts/gd/GDTest.gd";
+    
+    export default class Main extends godot.Node {
+        _ready(): void {
+            const gdTest: GDTest = GDTest.new();
+            gdTest.call("print_in_gd_test");
+        }
+    }
+    
+    ````
+
+> **Note:** The important thing here is that you use `new()` to instantiate and `call` to execute the function
