+### Building the project for testing
+
+To run the tests, we must build the debug version of `lianad`. Follow the instructions at [`doc/BUILD.md`](../doc/BUILD.md) but instead of running
+```
+$ cargo build --release
+```
+Run
+```
+$ cargo build
+```
+to build the daemon for testing.  
+The `lianad` and `liana-cli` binaries will be in the `target/debug` directory at the root of the
+repository.
