 ## Building
 
-`./build.sh`
+To build the Asahi Linux installer, run the following command:
+
+```sh
+./build.sh
+```
+
+By default this will build m1n1 with chainloading support. You can optionally set the following environment variables to customize the build:
+
+- `M1N1_STAGE1`: Path to a prebuilt m1n1 stage 1 binary.
+- `LOGO`: Path to a logo in ICNS format.
+
+These options are mainly useful for downstream distributions that want to customize or brand the installer.
+
+**Note*** *Before building the Asahi Linux installer, ensure that all submodules are initialized and updated. Run the following commands:*
+
+```sh
+git submodule update --init --recursive
+```
+
+### Build Script Overview
+
+The `build.sh` script performs several key steps to build the installer:
+
+- Set Environment Variables
+- Download Dependencies
+- Copies Files & Certificates
+- Build m1n1
+- Creates a targall of the package and saves it to the releases directory.
+
+## Deployment
+
+To deploy the built installer, use the upload.sh script:
+
+```sh
+./upload.sh [prod|dev]
+```
+
+prod: Deploys to the production directory.
+dev: Deploys to the development directory.
+
+
+## Testing the Installer
+
+To test the installer, use the following script:
+
+```sh
+test.sh
+```
