-# 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.
