This configuration assume you want to use mason.nvim to install (and update) your language servers. Note that after you install a language server with mason.nvim there is a good chance the server won't be able to initialize correctly the first time. Try to "refresh" the file with the command :edit, and if that doesn't work restart Neovim.
Note: lsp-zero requires Neovim v0.8 or greater.

})The following setup will add more "completion sources" to nvim-cmp. Adds more keybindings to the autocompletion plugin (nvim-cmp). And will add more snippets.
Warning: this configuration can be overwhelming for people (very) new to Neovim. I've seen people getting extremely confused because the autocompletion plugin works without a language server. Some of them deleted lsp-zero from their Neovim configuration because they don't know how to tweak it to their liking. So, if you find yourself overwhelmed use the "simple version" from the previous section as a starting point.
