+### As Vim plugin
+
+Once you have fzf installed, you can enable it inside Vim simply by adding the
+directory to `&runtimepath` as follows:
 
 ```vim
+" If installed using Homebrew
+set rtp+=/usr/local/opt/fzf
+
+" If installed using git
+set rtp+=~/.fzf
+```
+
+If you use [vim-plug](https://github.com/junegunn/vim-plug), the same can be
+written as:
+
+```vim
+" If installed using Homebrew
+Plug '/usr/local/opt/fzf'
+
+" If installed using git
+Plug '~/.fzf'
+```
+
+But instead of separately installing fzf on your system (using Homebrew or
+"git clone") and enabling it on Vim (adding it to `&runtimepath`), you can use
+vim-plug to do both.
+
+```vim
+" PlugInstall and PlugUpdate will clone fzf in ~/.fzf and run install script
 Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
+  " Both options are optional. You don't have to install fzf in ~/.fzf
+  " and you don't have to run install script if you use fzf only in Vim.
 ```
