+## Template ToDo list
+- [x] Create a new [IntelliJ Platform Plugin Template][template] project.
+- [ ] Get familiar with the [template documentation][template].
+- [ ] Verify the [pluginGroup](/gradle.properties), [plugin ID](/src/main/resources/META-INF/plugin.xml) and [sources package](/src/main/kotlin).
+- [ ] Review the [Legal Agreements](https://plugins.jetbrains.com/docs/marketplace/legal-agreements.html).
+- [ ] [Publish a plugin manually](https://plugins.jetbrains.com/docs/intellij/publishing-plugin.html?from=IJPluginTemplate) for the first time.
+- [ ] Set the Plugin ID in the above README badges.
+- [ ] Set the [Deployment Token](https://plugins.jetbrains.com/docs/marketplace/plugin-upload.html).
+- [ ] Click the <kbd>Watch</kbd> button on the top of the [IntelliJ Platform Plugin Template][template] to be notified about releases containing new features and fixes.
+
+<!-- Plugin description -->
+This Fancy IntelliJ Platform Plugin is going to be your implementation of the brilliant ideas that you have.
+
+This specific section is a source for the [plugin.xml](/src/main/resources/META-INF/plugin.xml) file which will be extracted by the [Gradle](/build.gradle.kts) during the build process.
+
+To keep everything working, do not remove `<!-- ... -->` sections. 
+<!-- Plugin description end -->
+
+## Installation
+
+- Using IDE built-in plugin system:
+
+  <kbd>Settings/Preferences</kbd> > <kbd>Plugins</kbd> > <kbd>Marketplace</kbd> > <kbd>Search for "%NAME%"</kbd> >
+  <kbd>Install Plugin</kbd>
+
+- Manually:
+
+  Download the [latest release](https://github.com/%REPOSITORY%/releases/latest) and install it manually using
+  <kbd>Settings/Preferences</kbd> > <kbd>Plugins</kbd> > <kbd>⚙️</kbd> > <kbd>Install plugin from disk...</kbd>
