+# Test run instructions
+
+To run corresponding tests in `Valida` some preparations have to be done.
+
+We assume, that one is in `valida` folder.
+
+Firstly, move into [scripts_and_tools](./scripts_and_tools/) directory.
+
+Next, run
+
+```sh
+./valida_setup.sh
+```
+
+This will fetch all necessary components to build Rist code in `Valida`.
+
+Next, to prove execution we need to build one of the tests, let`s use [simple_arithmetic_test](./tests/simple_arithmetic_test/) as an example.
+
+Run
+
+```sh
+./build-rust.sh simple_arithmetic_test
+```
+
+If run is succsessfull then you will see `simple_arithmetic_test`, `simple_arithmetic_test.ll`, `simple_arithmetic_test.o` files in the scripts directory.
+
+Next, we need prove execution, to do so run
+
+```sh
+./valida_prove.sh simple_arithmetic_test
+```
+
+If proof succsessfull, you will see `simple_arithmetic_test.proof` file in scripts derectory.
+
+If needed, proof can be verified as follows
+
+```sh
+./valida_verify.sh simple_arithmetic_test
+```
