@@ -6,12 +6,53 @@ Cube HAL for Linux is framework for building custom in-enclave Linux distributio
 
 HAL uses [Buildroot](https://buildroot.org/)'s [_External Tree_ mechanism](https://buildroot.org/downloads/manual/manual.html#outside-br-custom) for building custom distro:
 
+### Step 1: Clone the Buildroot Repository
+
+First, download the Buildroot source code from its repository.
+
 ```bash
 git clone https://gitlab.com/buildroot.org/buildroot.git
+```
+
+### Step 2: Clone the Cube Project Repository
+
+Next, download the Cube project, which will be used as an external layer in Buildroot.
+
+```bash
 git clone https://github.com/ultravioletrs/cube.git
+```
+
+### Step 3: Go to the Buildroot Directory
+
+```bash
 cd buildroot
+```
+
+### Step 4: Set Up the Build Configuration
+
+Run the following command to configure Buildroot with settings from the Cube project.
+
+```bash
 make BR2_EXTERNAL=../cube/hal/buildroot/linux cube_defconfig
-# Execute 'make menuconfig' only if you want to make additional configuration changes to Buildroot.
+```
+
+- `BR2_EXTERNAL=../cube/hal/buildroot/linux`: Tells Buildroot to use the external configuration files from the Cube project located at `../cube/hal/buildroot/linux`.
+- `cube_defconfig`: Loads the default configuration for Cube. This sets up Buildroot with settings that are specific to the Cube project.
+
+### Step 5 (Optional): Make Additional Configuration Changes
+
+If you want to adjust any settings manually, you can run the following command to customize the Buildroot configuration:
+
+```bash
 make menuconfig
+```
+
+This step is optional. If you don’t need to make any changes, you can skip it.
+
+### Step 6: Build the Project
+
+Finally, build the project by running:
+
+```bash
 make
 ```
