 **UNDER CONSTRUCTION**
 
-Set the `MIHI_DATABASE` environment variable to `test.sqlite3`.
+## Contributing
+
+This application is built like any other Rust project:
+
+```
+$ cargo build
+```
+
+In order to test things you need to provide a database for it. One is provided
+in the form of `testdata/test.sqlite3`. So take that and set the `MIHI_DATABASE`
+environment variable to its full path. And after that you will be able to run:
+
+```
+$ cargo test
+$ cargo clippy --all-targets --all-features
+```
