 * Install the ada language server and make sure it's in your $PATH.
 * Use your favorite Neovim plugin manager to add the default set of [LSP
   configuration files](https://github.com/neovim/nvim-lspconfig) to Neovim.
-* Enable the Ada Language Server by adding `:lua require('lspconfig').als.setup{}` to
-  your init.vim.
+* Add `require('lspconfig').ada_ls.setup{}` to your init.lua in order to enable
+  the Ada Language Server.
 
 If you would rather not have the ada language server in your path, you can give
 the lsp client an absolute path to the ALS executable:
 
 ```lua
-require('lspconfig').als.setup{ cmd = "/path/to/als/executable" }
+require('lspconfig').ada_ls.setup{ cmd = "/path/to/als/executable" }
 ```
 
 Configuring the language server's settings can be achieved like this:
 
 ```lua
-require('nvim_lsp').als.setup{
+require('lspconfig').ada_ls.setup{
   settings = {
     ada = {
       projectFile = "project.gpr";
