# Contribution Guide ## Getting Started Before reading this document, **please check out the official** [CONTRIBUTING.md](https://github.com/denoland/deno/blob/master/.github/CONTRIBUTING.md) **by Deno team**. This document aims to be a complement to the above guidelines. ## Test Release Build To run tests on release (instead of debug) build, ensure you have built the release version, and ```bash ./tools/test.py target/release ``` ## Adding a New Third Party Package Based on the type of the package, you might want to ensure the package is correctly recorded in either `package.json` or `Cargo.toml` . After the third party package is added in `third_party/`, submit a PR to [deno\_third\_party](https://github.com/denoland/deno_third_party). Once the third party PR is present, you will be able to submit PRs in deno repo that references to the corresponding commit and access the packages in CI. For adding a new Rust crate, you might want to look into `build_extra/rust/BUILD.gn` and adding a new `rust_crate` entry there. You might also need to insert the entry in [main\_extern](https://github.com/denoland/deno/blob/73fb98ce70b327d1236b9540f3839a89c5d22ef0/BUILD.gn#L20-L48) inside of `BUILD.gn`. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://denolib.gitbook.io/guide/contributing-guide.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
