Bunch of updates.

Needed to add syntaxes to syntaxes/ because apparently using
extra_syntaxes results in the default syntaxes not working anymore:

+## Overriding packages in NixOS
+
+In NixOS, it's sometimes desirable to override a package in order to extend
+or modify its behavior. For example, I override my Neovim to add plugins so
+they get all the benefits of being in the nix store. Here's how I do it.
+
+<!-- more -->
+
+```nix
+# in configuration.nix
+nixpkgs.overlays = [
+  (import ./overlays.nix)
+];
+
+# in overlays.nix
+self: super: {
+  neovim-mukund = self.callPackage ./packages/neovim-mukund.nix {};
+}
+
+# finally, in packages/neovim-mukund.nix
+{ pkgs }:
+  neovim.override {
+    vimAlias = true;
+    viAlias = true;
+    configure = {
+      packages.mukund-plugins = with pkgs.vimPlugins; {
+        start = [
+          ale
+          fzf-vim
+          # ...
+        ];
+      };
+    };
+  }
+
+# putting it all together
+environment.systemPackages = [
+  neovim-mukund
+];
+```
+
+### Bonus: Installing a single package from `main`
+
+If you need to install a single package from the `main` branch but keep the
+rest of your code on your nix channel (usually the main channel or
+`nixos-unstable`), then try this:
+
+```nix
+# in packages/neovim-mukund.nix
+let neovim-master = (import (fetchTarball "https://github.com/NixOS/nixpkgs/archive/master.tar.gz") {}).neovim
+in
+  environment.systemPackage = [
+    neovim-master
+  ]
+```
+This time, I'm fetching and installing from the `master.tar.gz` file. This is
+handy if there's an update upstream that you want to use immediately. For
+example, I often use this when `Discord` releases an update. Nixpkgs usually
+merges the version bump fairly quickly, but it doesn't reach the release
+channels for many days during which Discord is unusable.

 This is a list of places in Rust where implementing a trait or using a struct
 affects the syntax of your code. I think of these features as "magical" because
 using them can change the behavior of very basic Rust code (`let`, `for-in`,
