-Installation
+Setup
 ------------
 
-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`,
+     - macOS: `Preferences | Editor | Vim Emulation` & `Preferences | Keymap`,
+     - regular vim mappings in the  `~/.ideavimrc` file.

+Emulated Vim Plugins
+--------------------
+
+IdeaVim extensions emulate plugins of the original Vim. In order to use
+IdeaVim extensions, you have to enable them via this command in your `~/.ideavimrc`:
+
+    set <extension-name>
+
+Available extensions:
+
+##  easymotion
+
+* Setup:  
+    * Install [IdeaVim-EasyMotion](https://plugins.jetbrains.com/plugin/13360-ideavim-easymotion/)
+    and [AceJump](https://plugins.jetbrains.com/plugin/7086-acejump/) plugins.
+    * `set easymotion`
+* Emulates [vim-easymotion](https://github.com/easymotion/vim-easymotion)
+* Commands: All commands with the mappings are supported. See the [full list of supported commands](https://github.com/AlexPl292/IdeaVim-EasyMotion#supported-commands).
+
+##  surround
+
+* Setup: `set surround`
+* Emulates [vim-surround](https://github.com/tpope/vim-surround)
+* Commands: `ys`, `cs`, `ds`, `S`
+
+## multiple-cursors
+
+* Setup: `set multiple-cursors`
+* Emulates [vim-multiple-cursors](https://github.com/terryma/vim-multiple-cursors)
+* Commands: `<A-n>`, `<A-x>`, `<A-p>`, `g<A-n>`
+
+## commentary
+
+* Setup: `set commentary`
+* Emulates [commentary.vim](https://github.com/tpope/vim-commentary)
+* Commands: `gcc`, `gc + motion`, `v_gc`
+
+## ReplaceWithRegister
+
+* Setup: `set ReplaceWithRegister`
+* Emulates [ReplaceWithRegister](https://github.com/vim-scripts/ReplaceWithRegister)
+* Commands: `gr`, `grr`
+
+## argtextobj
+
+* Setup:
+    * `set argtextobj`
+    * By default, only the arguments inside parenthesis are considered. To extend the functionality
+      to other types of brackets, set `g:argtextobj_pairs` variable to a comma-separated
+      list of colon-separated pairs (same as VIM's `matchpairs` option), like
+      `let g:argtextobj_pairs="(:),{:},<:>"`. The order of pairs matters when
+      handling symbols that can also be operators: `func(x << 5, 20) >> 17`. To handle
+      this syntax parenthesis, must come before angle brackets in the list.
+* Emulates [argtextobj.vim](https://www.vim.org/scripts/script.php?script_id=2699)
+* Additional text objects: `aa`, `ia`
+
+## exchange [To Be Released]
+
+* Setup: `set exchange`
+* Emulates [vim-exchange](https://github.com/tommcdo/vim-exchange)
+* Commands: `cx`, `cxx`, `X`, `cxc`
+    
+## textobj-entire
+
+* Setup: `set textobj-entire`
+* Emulates [vim-textobj-entire](https://github.com/kana/vim-textobj-entire)
+* Additional text objects: `ae`, `ie`
+
