+# Git Commit Message Convention
+
+This project follows the [Conventional Commits](https://www.conventionalcommits.org/) specification for commit messages.
+
+## Format
+
+```
+<type>[optional scope]: <description>
+
+[optional body]
+
+[optional footer(s)]
+```
+
+## Types
+
+| Type | Description |
+|------|-------------|
+| `feat` | A new feature |
+| `fix` | A bug fix |
+| `docs` | Documentation only changes |
+| `style` | Changes that do not affect the meaning of the code (formatting, missing semicolons, etc.) |
+| `refactor` | A code change that neither fixes a bug nor adds a feature |
+| `perf` | A code change that improves performance |
+| `test` | Adding missing tests or correcting existing tests |
+| `build` | Changes that affect the build system or external dependencies |
+| `ci` | Changes to CI configuration files and scripts |
+| `chore` | Other changes that don't modify source or test files |
+| `revert` | Reverts a previous commit |
+
+## Rules
+
+1. **Limit the subject line to 50 characters** (72 character hard limit)
+2. **Use the imperative mood** in the subject line (e.g., "add feature" not "added feature")
+3. **Do not end the subject line with a period**
+4. **Use lowercase** for the description (e.g., "add feature" not "Add feature")
+5. **Separate subject from body with a blank line**
+6. **Wrap the body at 72 characters**
+7. **Use the body to explain what and why**, not how
+8. **Reference issues and pull requests** in the footer
+
+## Scope
+
+The scope should be the name of the package or area affected (e.g., `button`, `datepicker`, `theme`, `demo`).
+
+## Examples
+
+### Simple commit
+
+```
+feat(button): add loading state support
+```
+
+### Commit with body
+
+```
+fix(datepicker): correct month navigation overflow
+
+When navigating past December, the month index wrapped to a
+negative value instead of rolling over to January of the next year.
+```
+
+### Commit with breaking change
+
+```
+feat(theme)!: rename SemiColorPrimary to SemiColorBrand
+
+BREAKING CHANGE: The token SemiColorPrimary has been renamed to
+SemiColorBrand. Update all references in your custom theme files.
+```
+
+### Commit referencing an issue
+
+```
+fix(textbox): placeholder not visible in dark mode
+
+Closes #123
+```
+
+## Breaking Changes
+
+Breaking changes must be indicated by appending a `!` after the type/scope, or by including a `BREAKING CHANGE:` footer. Both methods may be used together.
+
+## Revert Commits
+
+When reverting a previous commit, use the `revert` type and reference the reverted commit SHA in the footer:
+
+```
+revert: feat(button): add loading state support
+
+Revert commit a1b2c3d.
+```
