 In addition to machine configurations, it also contains a bunch of shared modules, packages, and
 more.

-## Machines
+> [!WARNING]
+> Please read [Development - working on the PVV machines](./docs/development.md) before making
+> any changes, and [Secret management and `sops-nix`](./docs/secret-management.md) before adding
+> any credentials such as passwords, API tokens, etc. to the configuration.
+
+## Deploying to machines
+
+> [!WARNING]
+> Be careful to think about state when testing changes against the machines. Sometimes, a certain change
+> can lead to irreversible changes to the data stored on the machine. An example would be a set of database
+> migrations applied when testing a newer version of a service. Unless that service also comes with downwards
+> migrations, you can not go back to the previous version without losing data.
+
+To deploy the changes to a machine, you should first SSH into the machine, and clone the pvv-nixos-config
+repository unless you have already done so. After that, checkout the branch you want to deploy from, and rebuild:
+
+```bash
+# Run this while in the pvv-nixos-config directory
+sudo nixos-rebuild switch --update-input nixpkgs --update-input nixpkgs-unstable --no-write-lock-file --refresh --flake .# --upgrade
+```
+
+This will rebuild the NixOS system on the current branch and switch the system configuration to reflect the new changes.
+
+Note that unless you eventually merge the current changes into `main`, the machine will rebuild itself automatically and
+revert the changes on the next nightly rebuild (tends to happen when everybody is asleep).

-> [!WARNING]
-> Be careful to think about state when testing changes against the machines. Sometimes, a certain change
-> can lead to irreversible changes to the data stored on the machine. An example would be a set of database
-> migrations applied when testing a newer version of a service. Unless that service also comes with downwards
-> migrations, you can not go back to the previous version without losing data.
-
-To deploy the changes to a machine, you should first SSH into the machine, and clone the pvv-nixos-config
-repository unless you have already done so. After that, checkout the branch you want to deploy from, and rebuild:
-
-```bash
-# Run this while in the pvv-nixos-config directory
-sudo nixos-rebuild switch --update-input nixpkgs --update-input nixpkgs-unstable --no-write-lock-file --refresh --flake .# --upgrade
-```
-
-This will rebuild the NixOS system on the current branch and switch the system configuration to reflect the new changes.
-
-Note that unless you eventually merge the current changes into `main`, the machine will rebuild itself automatically and
-revert the changes on the next nightly rebuild (tends to happen when everybody is asleep).
