-Use the IDE's plugin manager to install the latest version of the plugin.
-Start the IDE normally and enable the Vim emulation using "Tools | Vim
-Emulator" menu item. At this point you must use Vim keystrokes in all editors.
+- IdeaVim can be installed via `Settings | Plugins`.
+See [detailed instructions](https://www.jetbrains.com/help/idea/managing-plugins.html#).
 
-If you wish to disable the plugin, select the "Tools | Vim Emulator" menu so
-it is unchecked. At this point your IDE will work with its regular keyboard
-shortcuts.
+- Use `Tools | Vim Emulator` to enable or disable emulation.
 
-Keyboard shortcut conflicts between the Vim emulation and the IDE can be
-resolved via "File | Settings | Editor | Vim Emulation", "File | Settings |
-Keymap" on Linux & Windows, and via "Preferences | Editor | Vim Emulation",
-"Preferences | Keymap" on macOS. They can also be resolved by key-mapping
-commands in your ~/.ideavimrc file.
+- Use `~/.ideavimrc` file as an analog of `~/.vimrc` ([details](#Files)). XGD standard is supported as well.
 
+- Shortcut conflicts can be resolved using:
+     - Linux & Windows: `File | Settings | Editor | Vim Emulation` & `File | Settings | Keymap`,
