 ## Embedded Library Support
 
-This driver now includes an embedded library feature that allows you to distribute a single binary without requiring users to set environment variables. The library for your platform is automatically embedded, extracted at runtime, and loaded dynamically.

+### Building from Source
+
+To build with embedded library support, follow these steps:
+
+```bash
+# Clone the repository
+git clone https://github.com/tursodatabase/limbo
+
+# Navigate to the Go bindings directory
+cd limbo/bindings/go
+
+# Build the library (defaults to release build)
 ./build_lib.sh
+
+# Alternatively, for faster builds during development:
+./build_lib.sh debug
 ```
 
+### Build Options:
+
+* Release Build (default): ./build_lib.sh or ./build_lib.sh release
+
+    - Optimized for performance and smaller binary size
+    - Takes longer to compile and requires more system resources
+    - Recommended for production use
+
+* Debug Build: ./build_lib.sh debug
+
+    - Faster compilation times with less resource usage
+    - Larger binary size and slower runtime performance
+    - Recommended during development or if release build fails
+
 If the embedded library cannot be found or extracted, the driver will fall back to the traditional method of finding the library in the system paths.
