+
+# Pull Request Conventions
+
+This page outlines pull request conventions and standards across Cadence repositories. For language-specific tooling, build instructions, and formatting details, refer to the CONTRIBUTING.md file in each repository.
+
+## Pull Request Titles
+
+### Conventional Commits Format
+
+All pull request titles should follow the [Conventional Commits](https://www.conventionalcommits.org/) format:
+
+```
+<type>(<optional scope>): <description>
+
+Examples:
+feat(worker): Add batch processing API
+fix(history): Resolve deadlock in workflow execution
+docs: Update getting started guide
+```
+
+**Types:**
+- **feat**: A new feature
+- **fix**: A bug fix
+- **docs**: Documentation only changes
+- **refactor**: Code change that neither fixes a bug nor adds a feature
+- **test**: Adding or updating tests
+- **chore**: Changes to build process, dependencies, or tools
+
+### PR Title Guidelines
+
+<!-- Source: https://github.com/cadence-workflow/cadence/blob/master/CONTRIBUTING.md#L253-L265 -->
+Follow the [Chris Beams guide](http://chris.beams.io/posts/git-commit/) to writing git commit messages. All PR titles should:
+
+- Start with UPPER case
+- Be specific (avoid generic titles like "bug fixes")
+- Use imperative mood ("Add feature" not "Added feature")
+
+**Examples from Cadence repositories:**
+- [Make sync activity retry multiple times before fetch history from remote](https://github.com/cadence-workflow/cadence/pull/1379)
+- [Enable archival config per domain](https://github.com/cadence-workflow/cadence/pull/1351)
+
+## Signing Commits
+
+The Developer Certificate of Origin (DCO) requires all commits to be signed before they can be merged to Cadence repositories. You can fulfill this requirement using either:
+
+- Signing every commit with `-s`: `git commit -s -m "Your commit message"`
+- Signing each commit with a GPG key
+
+### Setting up GPG key signing
+
+1. [Generate a new GPG key](https://docs.github.com/en/authentication/managing-commit-signature-verification/generating-a-new-gpg-key)
+2. [Add GPG key to your GitHub account](https://docs.github.com/en/authentication/managing-commit-signature-verification/adding-a-gpg-key-to-your-github-account)
+3. [Tell Git about your signing key](https://docs.github.com/en/authentication/managing-commit-signature-verification/telling-git-about-your-signing-key)
+4. Enable automatic signing:
+   ```bash
+   git config --global commit.gpgsign true
+   ```
