+# NixOS (matic - Framework 13 AMD AI 300)
+
+## Full Disk Encryption (LUKS + TPM2)
+
+The root partition is encrypted with LUKS2. TPM2 auto-unlock is configured so no passphrase is needed on boot.
+
+After a fresh install or kernel update, enroll the TPM2 key:
+
+```bash
+sudo systemd-cryptenroll --tpm2-device=auto /dev/nvme0n1p2
+```
+
+If the boot chain changes (firmware/kernel update), TPM2 will refuse and fall back to the passphrase. Re-enroll after booting with the passphrase.
+
+## Building and Switching
+
+```bash
+make build HOST=matic && make switch HOST=matic
+```
+
+Or use `boot` instead of `switch` for major config changes (avoids dbus reload issues):
+
+```bash
+sudo nixos-rebuild boot --flake .#matic --impure && sudo reboot
+```
