                          `gopher.setup`({user_config})
 Setup function. This method simply merges default config with opts table.
 You can read more about configuration at |gopher.nvim-config|
-Calling this function is optional, if you ok with default settings. Look |gopher.nvim.config-defaults|
+Calling this function is optional, if you ok with default settings.
+See |gopher.nvim.config-defaults|
 
 Usage ~
 `require("gopher").setup {}` (replace `{}` with your `config` table)
···
 Gopher.nvim implements most of its features using third-party tools.
 To install these tools, you can run `:GoInstallDeps` command
 or call `require("gopher").install_deps()` if you want to use lua api.
+By default dependencies will be installed asynchronously, to install them synchronously pass `{sync = true}` as an argument.
