-### Required dependencies
+### Optional dependencies
 
 - [nvim-notify](https://github.com/rcarriga/nvim-notify)
 
 ### Installation
 
 Using [packer.nvim](https://github.com/wbthomason/packer.nvim)
 
+Basinc setup will use `vim.notify()` for notifications:
 ```lua
 use {
   'mrded/nvim-lsp-notify',
-    requires = { 'rcarriga/nvim-notify' },
-    config = function()
-      require('lsp-notify').setup({})
-    end
+  config = function()
+    require('lsp-notify').setup({})
+  end
+}
+```
+
+You can also pass `notify` function, for example from [nvim-notify](https://github.com/rcarriga/nvim-notify):
+```lua
+use {
+  'mrded/nvim-lsp-notify',
+  requires = { 'rcarriga/nvim-notify' },
+  config = function()
+    require('lsp-notify').setup({
+      notify = require('notify'),
+    })
+  end
 }
 ```
