+### Commit message convention
+
+We follow the [conventional commits specification](https://www.conventionalcommits.org/en) for our commit messages:
+
+- `fix`: bug fixes, e.g. fix crash due to deprecated method.
+- `feat`: new features, e.g. add new method to the module.
+- `refactor`: code refactor, e.g. migrate from class components to hooks.
+- `docs`: changes into documentation, e.g. add usage example for the module..
+- `test`: adding or updating tests, eg add integration tests using detox.
+- `chore`: tooling changes, e.g. change CI config.
+
+Our pre-commit hooks verify that your commit message matches this format when committing.

 We have 3 types of basic plugins that you can use as a foundation for modifying functionality

+- `Plugin`
 The most trivial plugin interface that will act on any event payload going through the timeline.
 For example if you wanted to add something to the context object of any event payload as an enrichment.

 For example if you only wanted to act on `track` & `identify` events

+- `DestinationPlugin`
 A plugin interface most commonly used for device-mode destinations. This plugin contains an internal timeline that follows the same process as the analytics timeline,
 allowing you to modify/augment how events reach the particular destination.

 ### Advanced concepts
-- [`update(settings:)`]()
+- `update(settings:)`
 Use this function to react to any settings updates. This will be implicitly called when settings are updated.
 - OS Lifecycle hooks
 Plugins can also hook into lifecycle events by conforming to the platform appropriate protocol. These functions will get called implicitly as the lifecycle events are processed.
