+## Updating Nixpkgs
+
+Nixpkgs is the official package repository for Nix.
+
+The `nixpkgs` input is a reference to the [NixOS/nixpkgs repository](https://github.com/NixOS/nixpkgs/), updating this input will checkout the latest git commit. To update our pin of Nixpkgs:
+
+```
+nix flake lock --update-input nixpkgs
+```
+
+## Pushing development artifacts to Cachix
+
+Cachix is an easy-to-use cache for Nix packages. Instead of having each developer build Comm-specific packages locally, we can populate those packages in a Cachix cache and pull down the prebuilt packages.
+
+### Authorizing with Cachix
+
+To configure token authorization for Cachix:
+
+```
+nix shell nixpkgs#cachix
+cachix authtoken <auth token>
+```
+
+### Pushing development shell to Cachix
+
+To build and push development artifacts to Cachix:
+
+```
+nix build .#devShells.default
+cachix push comm ./result
+```
