+## Instructions
+
+The current setup for the OS image is:
+
+* eth0 as DHCP (WAN)
+* eth1 (R8169) renamed to enp1s0 and static IP: 192.168.254.199
+* No iptables created for the router
+* Kernel is conservative, 1.8GHz / 1.4GHz and can be set to 2.0GHz / 1.5GHz
+* 8GB SD size minimal.
+* all the build tools are installed
+* ssh installed, use ssh [email protected] or ssh ubuntu@IP_FROM_DHCP_WAN
+
+**Credentials**
+
+user / pass: ubuntu / ubuntu
+
+**Network**
+
+Netplan is not active, and you have to edit the file /etc/network/interfaces (with linux) to change the settings:

+**Flashing the Image**
+
+You need a linux box to burn your SD CARD.
+Download the files and find the device name for your SD CARD after is inserted:
+
+    dmesg|tail
+    [270176.904124] sd 6:0:0:0: [sdd] 31116288 512-byte logical blocks: (15.9 GB/14.8 GiB)
+    [270176.938132]  sdd: sdd1 sdd2
+
+Burn the Image file like this (taken from the above info):
+
+    ./flash_mainline_sdcard.sh /dev/sdd
+
+If you have an embedded sd card reader, look for /dev/mmcblkN where N is your sd card number
