 # Limbo driver for Go's `database/sql` library
 
-
 **NOTE:** this is currently __heavily__ W.I.P and is not yet in a usable state.
 
 This driver uses the awesome [purego](https://github.com/ebitengine/purego) library to call C (in this case Rust with C ABI) functions from Go without the use of `CGO`.
 
+## 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.
+
+To build with embedded library support:
+```
+# From the bindings/go directory
+./build_lib.sh
+```
+
+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.
 
 ## To use: (_UNSTABLE_ testing or development purposes only)
 
-### Linux | MacOS
+### Option 1: Using the embedded library (recommended)
+
+Build the driver with the embedded library as described above, then simply import and use. No environment variables needed!
+
+### Option 2: Manual library setup
+
+#### Linux | MacOS

+## Implementation Notes
+
+The embedded library feature was inspired by projects like [go-embed-python](https://github.com/kluctl/go-embed-python), which uses a similar approach for embedding and distributing native libraries with Go applications.
