 # Adding Plugins {#sec-additional-plugins}
 
-To add a new Neovim plugin, use `npins`
+There are two methods for adding new Neovim plugins to **nvf**. npins is the
+faster option that should be preferred if the plugin consists of pure Lua or
+Vimscript code. In which case there is no building required, and we can easily
+handle the copying of plugin files. Alternative method, which is required when
+plugins try to build their own libraries (e.g., in Rust or C) that need to be
+built with Nix to function correctly.
 
-Use:
+## With npins {#sec-npins-for-plugins}
 
-`nix-shell -p npins` or `nix shell nixpkgs#npins`
+npins is the standard method of adding new plugins to **nvf**. You simply need
+the repository URL for the plugin, and can add it as a source to be built
+automatically with one command. To add a new Neovim plugin, use `npins`. For
+example:
+
+```bash
+nix-shell -p npins # or nix shell nixpkgs#npins if using flakes
+```
 
 Then run:
 
-`npins add --name <plugin name> github <owner> <repo> -b <branch>`
+```bash
+npins add --name <plugin name> github <owner> <repo> -b <branch>
+```
 
-Be sure to replace any non-alphanumeric characters with `-` for `--name`
+::: {.note}
 
-For example 
+Be sure to replace any non-alphanumeric characters with `-` for `--name`. For
+example
 
-`npins add --name lazydev-nvim github folke lazydev.nvim -b main`
+```bash
+npins add --name lazydev-nvim github folke lazydev.nvim -b main
+```
 
-You can now reference this plugin as a **string**.
+:::
+
+Once the `npins` command is done, you can start referencing the plugin as a
+**string**.
 
 ```nix
-config.vim.startPlugins = ["lazydev-nvim"];
+{
+  config.vim.startPlugins = ["lazydev-nvim"];
+}
+```
+
+## Packaging Complex Plugins {#sec-pkgs-for-plugins}
+
+[blink.cmp]: https://github.com/Saghen/blink.cmp
+
+Some plugins require additional packages to be built and substituted to function
+correctly. For example [blink.cmp] requires its own fuzzy matcher library, built
+with Rust, to be installed or else defaults to a much slower Lua implementation.
+In the Blink documentation, you are advised to build with `cargo` but that is
+not ideal since we are leveraging the power of Nix. In this case the ideal
+solution is to write a derivation for the plugin.
+
+We use `buildRustPackage` to build the library from the repository root, and
+copy everything in the `postInstall` phase.
+
+```nix
+postInstall = ''
+  cp -r {lua,plugin} "$out"
+
+  mkdir -p "$out/doc"
+  cp 'doc/'*'.txt' "$out/doc/"
+
+  mkdir -p "$out/target"
+  mv "$out/lib" "$out/target/release"
+'';
+```
+
+In a similar fashion, you may utilize `stdenv.mkDerivation` and other Nixpkgs
+builders to build your library from source, and copy the relevant files and Lua
+plugin files in the `postInstall` phase. Do note, however, that you still need
+to fetch the plugin sources somehow. npins is, once again, the recommended
+option to fetch the plugin sources. Refer to the previous section on how to use
+npins to add a new plugin.
+
+Plugins built from source must go into the `flake/pkgs/by-name` overlay. It will
+automatically create flake outputs for individual packages. Lastly, you must add
+your package to the plugin builder (`pluginBuilders`) function manually in
+`modules/wrapper/build/config.nix`. Once done, you may refer to your plugin as a
+**string**.
+
+```nix
+{
+  config.vim.startPlugins = ["blink-cmp"];
+}
 ```
