+###Setup Git Pre-commit hook script (Optional)
+
+The purpose of setting up this optional pre-commit hook is so that the `lintKotlin` Gradle task runs each time you as a developer create a commit. Although the Travis build will run `lintKotlin` in the cloud, running this locally will allow you to catch Kotlin Lint violations early in the development cycle without having to wait for Travis's build report.
+
+To enable the script, execute the following commands starting from the project's root directory:
+
+	cd .git/hooks
+	ln -s ../../scripts/pre-commit.sh pre-commit
