+## Setup
+
+This project is based on Rust - The easiest way to get setup is to us the [rustup install system](https://rustup.rs/).
+
+To perform an end to end integration test you may want to use a [free cluster](https://cloud.ibm.com/docs/containers?topic=containers-getting-started#clusters_gs) on IBM Cloud.
+
+Instructions on how to install are available in the main [README.md](https://github.com/IBM/core-dump-handler#installing-the-chart)
+
+## Testing
+PR's that modify the codebase will be expected to run against a cluster using the `integration/run.sh` before being accepted.
+
+## Coding style guidelines
+Code contributions should be PR'd with `cargo fmt` ran
