-Init program for initrd
\ No newline at end of file
+Kira-Linux init program for initrd
+
+
+1. It looks for partitoin with GPT labelve **bee-root** what will shown in dev tree as **/dev/disk/by-partlabel/bee-root**
+And this partition should be formated to bcachefs.
+
+2. Nyanit checks if bcachefs is encrypted, and asks for unlock password if it is.
+
+3. Then it mounts it to **/mnt/bee-root**.
+
+4. And looks for snapshots with name pattern **/mnt/bee-root/bzz_snaps/bzz-yyyy-mm-ddTHH-MM-SS**
+
+5. If no snapshots are found it calls **switch_root** for **/mnt/bee-root**
+
+6. Othervise vait for F2 for few seconds.
+And if F2 pressed provides list of snapshoots to boot from.
+
+7. After some snapshoot or just **/mnt/bee-root** is selected, Nyanit doing **switch_root** to it.
