 ## Setup
 
-Options are currently being migrated into the setup function, you need to run `require'nvim-tree'.setup()` in your personal configurations.
 Setup should be run in a lua file or in a lua heredoc (`:help lua-heredoc`) if using in a vim file.
-Note that options under the `g:` command should be set **BEFORE** running the setup function.
-These are being migrated to the setup function incrementally, check [this issue](https://github.com/kyazdani42/nvim-tree.lua/issues/674) if you encounter any problems related to configs not working after update.
+Legacy `g:` options have been migrated to the setup function. See [this issue](https://github.com/kyazdani42/nvim-tree.lua/issues/674) for information on migrating your configuration.
