+## Running Luau 
+
+Luau can be interesting for its typing system.
+However, for it to be useful, it needs to be integrated both in the bevy lua runtime and also a language server much like luau-lsp.
+
+This example will provide snippets to integrate `luau-lsp` and `bevy_mod_scripting` within VSCode
+
+### Luau package import
+
+The first step for packages to load each other is to enable the `unsafe_lua_modules` in `cargo.toml`, example:
+```toml
+[dependencies]
+bevy_mod_scripting = { version = "0.13.0", features = ["luau","unsafe_lua_modules"] }
+```
+
+The second step to make luau`require("./source/to/package")` work within bevy, the `LUA_PATH` needs to be exported as an environment variable. This also probably needs to be initialized at runtime as the location of the bevy executable may change.
+Here is an example snippet that updates the path at runtime.
+
+```rust
+fn main() {
+    // Set the LUA_PATH env variable
+    let mut assets_path = std::env::current_dir().expect("Failed to get current dir");
+    assets_path.push("assets");
+
+    let assets_str = assets_path
+        .to_str()
+        .expect("Failed to convert path to str")
+        .replace("\\", "/");
+
+    let luau_package_path = format!("{}{}", assets_str, "/?.luau");
+
+    unsafe{
+        env::set_var("LUA_PATH", luau_package_path);
+    }
+
+    let mut app = App::new();
+    app.add_plugins(BMSPlugin);
+
+    // More code adding luau scripts, callbacks and else.
+
+    app.run();
+}
+
+```
+
+Assuming a folder structure that is the following,
+- assets
+  - scenarios
+    - scenario.luau
+  - scripts
+    - Template.luau
+
+`scenario.luau` should be able to import Template.luau using the following lines:
+
+```lua
+local Template = require("./../scripts/Template")
+```
+
+
+### Luau-lsp
+
+To have luau autocomplete and type check within VSCode install the Luau Language Server plugin.
+
+To avoid excessive underlines within the luau-lsp, a `.luaurc` file needs to be added in the root of the project.
+
+`.luaurc`
+```json
+{
+	"languageMode": "strict",
+	"lint": { "*": true, "LocalUnused": false, "FunctionUnused": false },
+	"lintErrors": true,
+	"globals": ["world" , "construct", "types", "package"]
+}
+```
+
+Additionally, because luau-lsp is focused towards Roblox plugins, additional VSCode config should be inserted to avoid incorrect autocomplete.
+
+`.vscode/settings.json`
+```json
+{
+  "luau-lsp.platform.type": "standard",
+  "luau-lsp.types.robloxSecurityLevel": "None",
+  "luau-lsp.sourcemap.enabled": false,
+  "luau-lsp.sourcemap.autogenerate": false
+}
+```
