+You can install `rust_hdl` automatically in Neovim using [`:Mason`](https://github.com/williamboman/mason.nvim), in Mason the package is called `rust_hdl`. If you don't have `:Mason`, you can simply install the binary as previously described.

 Neovim provides an LSP client to the VHDL_LS language server. Download the  
 VHDL_LS release. The binary must be on the path and executable (if you can run  
 "vhdl_ls -h" in the terminal then you're good).

+## Configuration
 The language server needs to know your library mapping to perform full analysis of the code. For this it uses a configuration file in the [TOML](https://github.com/toml-lang/toml) format named `vhdl_ls.toml`.
 
 `vhdl_ls` will load configuration files in the following order of priority (first to last):
