+# Rust examples for Iroha 2
+
+## Running the examples
+
+To run the examples, you need to install [`cargo-nextest`](https://nexte.st/) first.
+
+```bash
+cargo install cargo-nextest
+```
+
+After it is installed, type:
+
+```bash
+cargo nextest run
+```
+
+You'll Cargo install the packages that are needed for the tests and the test code will run.
