 ### Error Handling
 
-The library uses structured error types for better error handling (see [errors.go](./kernel/errors.go)).

-### Runtime Dependencies
-
-Your Go application will have a runtime dependency on the shared `libbitcoinkernel` library produced by `make build-kernel` in `/path/to/go-bitcoinkernel/depend/bitcoin/build`. Do not delete or move these built library files as your application needs them to run.
