+## Project structure
+
+-   `config` - config file with all constants and state init for working with contract
+-   `wrappers` - wrapper classes (implementing `Contract` from ton-core) for the contracts, including any [de]serialization primitives and compilation functions.
+-   `tests` - tests for the contracts.
+-   `scripts` - scripts used by the project, mainly the deployment scripts.
+
+## How to use
+
+### Test
+
+`npx blueprint test`
+
+### Deploy or run selected script
+
+`npx blueprint run`
