+
+## Project structure
+
+The project is split up into several crates in the `crates/` directory:
+
+* Libraries:
+    * [**cdk**](./crates/cdk/): Rust implementation of Cashu protocol.
+    * [**cdk-sqlite**](./crates/cdk-sqlite/): Sqlite Storage backend
+    * [**cdk-redb**](./crates/cdk-redb/): Redb Storage backend
+* Binaries:
+    * [**cdk-cli**](./crates/cdk-cli/): Cashu wallet CLI
