-System configuration files for NixOS.
+My personal NixOS + home-manager configuration files.
 
-Fairly minimal setup and installation, to be paired with [[https://git.xenia.me.uk/pixelifytica/home-manager.git][a
-home-manager config]] to get the full user setup.
+To set up without cloning the repository (assuming an already running
+NixOS system), run:
+#+begin_src bash
+  sudo nixos-rebuild switch --flake "git+https://git.xenia.me.uk/pixelifytica/nixos.git?ref=main"\#$(hostname)
+#+end_src

+* Password store setup
+** Transfer GPG key(s)
+#+begin_src bash
+  # Export keys on existing machine
+  gpg -a --export > publickeys.asc
+  gpg -a --export-secret-keys > privatekeys.asc
+  # Import key on new machine
+  gpg --import privatekeys.asc; gpg --import publickeys.asc
+  # Edit (for each key) to set trust
+  gpg --edit-key evie@xenia.me.uk
+#+end_src
+** Clone password-store repository
+#+begin_src bash
+  git -c credential.helper='' clone https://git.xenia.me.uk/pixelifytica/pass $PASSWORD_STORE_DIR
+#+end_src
+
+* Email setup
+** Proton
+*** Bridge
+Start Proton Mail Bridge application, if needed configure to store
+using =SecretService= and log in. Application will auto-start with
+plasma session.
+*** Password
+Get password from ~protonmail-bridge~, save to ~password-store~:
+#+begin_src bash
+  pass insert mbsync/$(hostname)/proton
+  # Insert pass at prompt
+#+end_src
+** iCloud
+*** Password
+If not already done, save password to ~password-store~:
+#+begin_src bash
+  pass insert mbsync/$(hostname)/icloud
+  # Insert pass at prompt
+#+end_src
+This will be synced across devices so only needs doing once
+** Outlook
+*** Password
+If not already done, save password to ~password-store~:
+#+begin_src bash
+  pass insert mbsync/$(hostname)/outlook
+  # Insert pass at prompt
+#+end_src
+This will be synced across devices so only needs doing once
+*** Configuration
+Run src_bash{davmail-setup} to automate this process.
+
+On first run (or if token expires), stop systemd service and run manually to complete manual auth. Token will stay valid for a little while (no idea how long specifically).
+#+begin_src bash
+  # Restart service to ensure ~/.davmail.properties exists
+  systemctl --user restart davmail.service
+  # Run to use manual authentication
+  systemctl --user stop davmail.service && davmail -notray ~/.davmail.properties
+  # Restart again so that service picks up available ports
+  systemctl --user restart davmail.service
+#+end_src
+
+* Flathub setup
+#+begin_src bash
+  flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
+#+end_src
