+# ProcessingInstructions
+
+See the [Processing instructions's README](../README.md) for more information. In our case, we cannot use Borsh for serialization, as we're constrained by the `Steel` framework dependency on PODs (Plain Old Data).
+
+## Building
+
+```sh
+cargo build-sbf
+
+```
+## Tests
+
+This project includes both:
+- Rust tests: [`program/tests`](/program/tests) directory.
+- Node.js tests using [Bankrun](https://kevinheavey.github.io/solana-bankrun/): [`tests`](/tests) directory.
+
+```sh
+# rust tests
+cargo test-sbf 
+
+# node tests
+pnpm build-and-test # this will also build the program
+#or 
+pnpm test # if you have already built the program
+```
