 ### Step 5: Push your feature branch to your fork
 
-We use [semantic-versioning](https://semver.org/) and the [conventional commit message format](https://www.conventionalcommits.org/en/v1.0.0/). Keep a separate feature branch for each issue you want to address. As you develop code, continue to push code to your remote feature branch. Example:

+**Important:** When editing the manual part of the SDK, commits and pull requests should include the `boxsdk` scope. For general changes that don't affect a specific part (e.g., documentation updates, build configuration), the scope is optional. Examples:
 
 ```
-tag: short description
+tag(scope): short description
+tag: short description (when scope is not applicable)
+
 longer description here if necessary.
 ```
 
-The message summary should be a one-sentence description of the change, and it must be 72 characters in length or shorter. For a list of tags, please [click here](https://github.com/commitizen/conventional-commit-types/blob/master/index.json). Note that you must include the `!` for breaking changes (e.g. `feat!: removed old apis`).
+Examples with scope:
+- `feat(boxsdk): add new file upload feature`
+- `fix(boxsdk): correct type definitions`
+- `feat(boxsdk)!: remove deprecated endpoints`
