+Before diving into the plugin development and everything that happens around, it is worth mentioning the fundamental
+idea behind the GitHub Templates: by creating a new project using the current template, you start with no history
+and no reference to this repository - it is the cut corner for creating a new repository with copy-pasting the content
+or cloning repositories and clearing the history by your own.
+
+The only thing that you have to do is clicking the **Use this template** button.
+
+![Use this template][file:getting-started_use-this-template.png]
+
+After creating your blank project from the template, there will be the [Template Cleanup][file:template_cleanup.yml]
+workflow triggered to override or remove template-specific configuration, like plugin name, current changelog, etc.
+
+As a last step, it is required to manually specify the `pluginName` and `pluginGroup` in the `gradle.properties` file.
