+===== Raspberry support =====
+Brmdoor was tried on:
+  * Raspberry 1B (very slow import, but works ok)
+  * Raspberry 3B+
+  * Raspberry 4B
+Tested Raspbian 9 and 10 (Raspi OS 2021-03-04). Still works on 2023-09-17, when we needed to drop ''pysftp'' and use ''paramiko'' directly, allows to use ECDSA and Ed25519 keys.
+Raspberry 1 and 2 - it's just slow, everything is slow there. Raspberry 3B+ or 4 with USB boot and USB flash instead of SDcard recommended.
+Make sure you enable SPI in device tree or ''dtparam=spi=on'' in ''/boot/config.txt'' depending on Raspi model otherwise reader won't work. Raspi 3B+ boots from USB out of the box, 4B needs enabling it manually. Latest Raspbian does not enable ssh after install put empty file named ''ssh'' in ''/boot'' directory to enable.
