+This is the Buildroot repoistory used to build system images and updates for the MynaPlayer project.
+
+BUILDING
+--------
+
+Building MynaPlayer is a process, though it requires decent hardware.
+
+Set up the required source code:
+
+```
+mkdir MYNA && cd MYNA
+git clone -b v3.0.7 'https://github.com/OpenVPN/easy-rsa'
+git clone -b 2020.05.x 'https://git.buildroot.net/buildroot'
+git clone 'https://git.lumina-sensum.com/git/LuminaSensum/buildroot-MynaPlayer.git'
+export BR2_EXTERNAL="$PWD/buildroot-MynaPlayer"
+cd buildroot
+git am ../buildroot-MynaPlayer/buildroot-patches/*.patch
+cd ..
+```
+
+Create keys for RAUC updates:
+
+```
+cd easy-rsa
+sed -i "s/extendedKeyUsage/#extendedKeyUsage/g" easy-rsa/easyrsa3/x509-types/code-signing
+./easyrsa3/easyrsa init-pki
+./easyrsa3/easyrsa build-ca
+./easyrsa3/easyrsa gen-req rauc
+./easyrsa3/easyrsa sign-req code-signing rauc
+cd ..
+echo "Certificate authority: $PWD/easy-rsa/pki/ca.crt" > certs.txt
+echo "Private key: $PWD/easy-rsa/pki/private/rauc.key" >> certs.txt
+echo "Public key: $PWD/easy-rsa/pki/issued/rauc.crt" >> certs.txt
+mv certs.txt buildroot-MynaPlayer/board/myna-player-odyssey/utilities/certs.txt
+```
+
+Build the image:
+
+```
+cd buildroot
+utils/brmake O=output_initramfs myna_player_odyssey_initramfs_defconfig
+utils/brmake O=output_initramfs toolchain
+utils/brmake O=output_initramfs -j8
+# If you get errors, run 'make O=output_initramfs -j1' to see the messages
+utils/brmake O=output_rootfs myna_player_odyssey_defconfig
+utils/brmake O=output_rootfs toolchain
+utils/brmake O=output_rootfs -j8
+# If you get errors, run 'make O=output_rootfs -j1' to see the messages
+cd ..
+```
+
+Copy RAUC bundles and keys to a server (jookia.org in this example):
+
+```
+ls buildroot/output_rootfs/images/
+# Find the file ending in *.raucb
+# You can also just flash MynaPlayer.img using dd but it takes a long time
+mv buildroot/output_rootfs/images/bundle-MynaPlayer-2020-08-06.fe2ca3ce-be36-4f33-94d4-e295cd0518be.raucb /usr/local/webapps/jookia/
+cp $PWD/easy-rsa/pki/ca.crt /usr/local/webapps/jookia
+```
+
+Install the update on the device from the server (jookia.org in this example):
+
+```
+wget 'https://www.jookia.org/ca.crt'
+cp /etc/rauc/keyring.pem{,.bak}
+mv ca.crt /etc/rauc/keyring.pem
+rauc install https://www.jookia.org/bundle-MynaPlayer-2020-08-06.6d113d3a-f77f-447a-ad7d-b8d605824c00.raucb
+mv /etc/rauc/keyring.pem{.bak,}
+reboot
+```
+
+Future updates won't need to copy the keyring, a single 'rauc install'
+invocation should download and install the image without trouble.
+
+You should now be running a system you've just built (check the kernel build date):
+
+```
+uname -a
+# Linux MynaPlayer 5.8.0 #3 SMP PREEMPT Thu Aug 6 03:21:30 EDT 2020 armv7l GNU/Linux
+```
