 ## Build Instructions
 
 ### Step 1: Checkout Chromium
@@ -18,45 +35,71 @@ This guide will walk you through building Nxtscape from source on macOS.
 First, you need to get the Chromium source code. Follow the official Chromium instructions:
 
 1. Visit the [Chromium Get the Code guide](https://www.chromium.org/developers/how-tos/get-the-code/)
-2. Follow the macOS-specific instructions to set up depot_tools and fetch Chromium
+2. Follow the platform-specific instructions to set up depot_tools and fetch Chromium
-3. Clone the Chromium repository into a `build` directory inside your nxtscape repository:
+3. Note the path to your chromium/src directory (you'll need it for building)
+
+### Step 2: Build BrowserOS
+
+Navigate to the BrowserOS build system:
 
 ```bash
-cd /path/to/nxtscape
+cd packages/browseros
-mkdir build
-cd build
-# Follow Chromium checkout instructions here
 ```
 
-### Step 2: Apply Nxtscape Patches
+#### Debug Build (for development):
-
-Once you have Chromium checked out, the Nxtscape patches need to be applied to customize the browser with AI features.
-
-### Step 3: Build Nxtscape
-
-Nxtscape provides a Python build script that handles the compilation process.
-
-#### For Debug Build:
-```bash
-python build/build.py --build --build-type debug
-```
-
-#### For Release Build:
-```bash
-python build/build.py --build --build-type release
-```
-
-**Note:** The build process typically takes around 3 hours on an M4 Max laptop. Build times may vary based on your hardware specifications.
-
-### Step 4: Run Nxtscape
-
-After the build completes successfully, you can run Nxtscape using:
 
 ```bash
-out/Default/Nxtscape.app/Contents/MacOS/Nxtscape --use-mock-keychain
+# macOS
+python build/build.py --config build/config/debug.macos.yaml --chromium-src /path/to/chromium/src --build
+
+# Linux
+python build/build.py --config build/config/debug.linux.yaml --chromium-src /path/to/chromium/src --build
+
+# Windows
+python build/build.py --config build/config/debug.windows.yaml --chromium-src /path/to/chromium/src --build
 ```
 
-The `--use-mock-keychain` flag is used to avoid keychain permission prompts during development.
+#### Release Build (for production):
+
+```bash
+# macOS
+python build/build.py --config build/config/release.macos.yaml --chromium-src /path/to/chromium/src --build
+
+# Linux
+python build/build.py --config build/config/release.linux.yaml --chromium-src /path/to/chromium/src --build
+
+# Windows
+python build/build.py --config build/config/release.windows.yaml --chromium-src /path/to/chromium/src --build
+```
+
+**Note:** The build process typically takes 1-3 hours on modern hardware. Build times may vary based on your hardware specifications.
+
+### Step 3: Run BrowserOS
+
+After the build completes successfully, you can run BrowserOS:
+
+#### macOS Debug Build:
+```bash
+# ARM64 (Apple Silicon)
+out/Default_arm64/BrowserOS\ Dev.app/Contents/MacOS/BrowserOS\ Dev --user-data-dir=/tmp/test-profile
+
+# x64 (Intel)
+out/Default_x64/BrowserOS\ Dev.app/Contents/MacOS/BrowserOS\ Dev --user-data-dir=/tmp/test-profile
+```
+
+#### macOS Release Build:
+```bash
+# ARM64 (Apple Silicon)
+out/Default_arm64/BrowserOS.app/Contents/MacOS/BrowserOS --user-data-dir=/tmp/test-profile
+
+# x64 (Intel)
+out/Default_x64/BrowserOS.app/Contents/MacOS/BrowserOS --user-data-dir=/tmp/test-profile
+```
+
+#### Linux and Windows:
+The built binary will be located in the `out/Default_x64/` directory. Run it with the `--user-data-dir` flag to create an isolated test profile.
+
+The `--user-data-dir` flag is useful for creating isolated test profiles during development.
