				-- LSP is an initialism you've probably heard, but might not understand what it is.
				--
				-- LSP stands for Language Server Protocol. It's a protocol that helps editors
				-- and language tooling communicate in a standardized fashion.
				--
				-- In general, you have a "server" which is some tool built to understand a particular
				-- language (such as `gopls`, `lua_ls`, `rust_analyzer`, etc.). These Language Servers
				-- (sometimes called LSP servers, but that's kind of like ATM Machine) are standalone
				-- processes that communicate with some "client" - in this case, Neovim!
				--
				-- LSP provides Neovim with features like:
				--  - Go to definition
				--  - Find references
				--  - Autocompletion
				--  - Symbol Search
				--  - and more!
				--
				-- Thus, Language Servers are external tools that must be installed separately from
				-- Neovim. This is where `mason` and related plugins come into play.
				--
				-- If you're wondering about lsp vs treesitter, you can check out the wonderfully
				-- and elegantly composed help section, `:help lsp-vs-treesitter`

				--  This function gets run when an LSP attaches to a particular buffer.
				--    That is to say, every time a new file is opened that is associated with
				--    an lsp (for example, opening `main.rs` is associated with `rust_analyzer`) this
				--    function will be executed to configure the current buffer
