 ### Benchmark
 
 **TODO**
+
+## Contributing
+
+### Pre-submission Checks
+
+Before submitting a Pull Request, please ensure your code passes the following checks:
+
+```bash
+# Run clippy with all warnings treated as errors (warnings will be treated as errors)
+cargo clippy --all-targets --all-features -- -D warnings
+
+# Check code formatting (requires nightly toolchain)
+cargo +nightly fmt --all --check
+```
+
+**Both commands must complete without any warnings.** The clippy check treats all warnings as errors, and the formatter check ensures code follows the project style guide. Only PRs that pass these checks will be accepted for merge.
+
+If the formatting check fails, you can automatically fix formatting issues by running:
+
+```bash
+cargo +nightly fmt --all
+```
+
+### Buck2 Build Requirements
+
+This project builds with Buck2. Please install both Buck2 and `cargo-buckal` before development:
+
+```bash
+# Install buck2: download the latest release tarball from
+# https://github.com/facebook/buck2/releases, extract the binary,
+# and place it in ~/.cargo/bin (ensure ~/.cargo/bin is on PATH).
+# Example (replace <tag> and <platform> with the latest for your OS):
+wget https://github.com/facebook/buck2/releases/download/<tag>/buck2-<platform>.tar.gz
+tar -xzf buck2-<platform>.tar.gz
+mv buck2 ~/.cargo/bin/
+
+# Install cargo-buckal (requires Rust toolchain)
+cargo install --git https://github.com/buck2hub/cargo-buckal.git
+```
+
+Pull Requests must also pass the Buck2 build:
+
+```bash
+cargo buckal build
+```
+
+When you update dependencies in Cargo.toml, regenerate Buck metadata and third-party lockfiles:
+
+```bash
+cargo buckal migrate
+```
+
