+# Contributing to JavaScriptKit
+
+Thank you for considering contributing to JavaScriptKit! We welcome contributions of all kinds and value your time and effort.
+
+## Getting Started
+
+### Reporting Issues
+- If you find a bug, have a feature request, or need help, please [open an issue](https://github.com/swiftwasm/JavaScriptKit/issues).
+- Provide as much detail as possible:
+  - Steps to reproduce the issue
+  - Expected vs. actual behavior
+  - Relevant error messages or logs
+
+### Setting Up the Development Environment
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/swiftwasm/JavaScriptKit.git
+   cd JavaScriptKit
+   ```
+
+2. Install **OSS** Swift toolchain (not the one from Xcode):
+    <details>
+    <summary>For macOS users</summary>
+
+    ```bash
+    (
+        SWIFT_TOOLCHAIN_CHANNEL=swift-6.0.2-release;
+        SWIFT_TOOLCHAIN_TAG="swift-6.0.2-RELEASE";
+        SWIFT_SDK_TAG="swift-wasm-6.0.2-RELEASE";
+        pkg="$(mktemp -d)/InstallMe.pkg"; set -ex;
+        curl -o "$pkg" "https://download.swift.org/$SWIFT_TOOLCHAIN_CHANNEL/xcode/$SWIFT_TOOLCHAIN_TAG/$SWIFT_TOOLCHAIN_TAG-osx.pkg";
+        installer -pkg "$pkg" -target CurrentUserHomeDirectory;
+        export TOOLCHAINS="$(plutil -extract CFBundleIdentifier raw ~/Library/Developer/Toolchains/$SWIFT_TOOLCHAIN_TAG.xctoolchain/Info.plist)";
+        swift sdk install "https://github.com/swiftwasm/swift/releases/download/$SWIFT_SDK_TAG/$SWIFT_SDK_TAG-wasm32-unknown-wasi.artifactbundle.zip";
+    )
+    ```
+
+    </details>
+
+    <details>
+    <summary>For Linux users</summary>
+    Install Swift 6.0.2 by following the instructions on the <a href="https://www.swift.org/install/linux/tarball/">official Swift website</a>.
+
+    ```bash
+    (
+        SWIFT_SDK_TAG="swift-wasm-6.0.2-RELEASE";
+        swift sdk install "https://github.com/swiftwasm/swift/releases/download/$SWIFT_SDK_TAG/$SWIFT_SDK_TAG-wasm32-unknown-wasi.artifactbundle.zip";
+    )
+    ```
+
+    </details>
+
+3. Install dependencies:
+   ```bash
+   make bootstrap
+   ```
+
+### Running Tests
+- Run unit tests:
+  ```bash
+  make unittest SWIFT_SDK_ID=wasm32-unknown-wasi
+  ```
+- Run integration tests:
+  ```bash
+  make test SWIFT_SDK_ID=wasm32-unknown-wasi
+  ```

 directory for more information in this more advanced use case.
 
-## Manual toolchain installation
-
-This library only supports [`swiftwasm/swift`](https://github.com/swiftwasm/swift) toolchain distribution.
-The toolchain can be installed via [`swiftenv`](https://github.com/kylef/swiftenv), in
-the same way as the official Swift nightly toolchain.
-
-You have to install the toolchain manually when working on the source code of JavaScriptKit itself,
-especially if you change anything in the JavaScript runtime parts. This is because the runtime parts are
-embedded in `carton` and currently can't be replaced dynamically with the JavaScript code you've
-updated locally.
-
-Just pass a toolchain archive URL for [the latest SwiftWasm 5.6
-release](https://github.com/swiftwasm/swift/releases/tag/swift-wasm-5.6.0-RELEASE) appropriate for your platform:
-
-```sh
-$ swiftenv install "https://github.com/swiftwasm/swift/releases/download/swift-wasm-5.6.0-RELEASE/swift-wasm-5.6.0-RELEASE-macos_$(uname -m).pkg"
-```
-
-You can also use the `install-toolchain.sh` helper script that uses a hardcoded toolchain snapshot:
-
-```sh
-$ ./scripts/install-toolchain.sh
-$ swift --version
-Swift version 5.6 (swiftlang-5.6.0)
-Target: arm64-apple-darwin20.6.0
-```
