+## Build HOWTO
+
+Pull sources:
+`$ cd ~/`
+`$ mkdir hikey960`
+`$ cd hikey960`
+`$ repo init -u [email protected]:svistelnikoff/android_manifest.git -b gl-hikey960`
+`$ repo sync -j4 -c -f`
+
+Download and extract HDMI proprietary binaries for Hikey960 (from the project home folder):
+`$ wget https://dl.google.com/dl/android/aosp/arm-hikey960-OPR-cf4e0c80.tgz`
+`$ tar xzf arm-hikey960-OPR-cf4e0c80.tgz`
+`$ ./extract-arm-hikey960.sh`
+
+Build
+`$ cd hikey960`
+`$ . ./build/envsetup.sh`
+`$ lunch hikey960-userdebug`
+`$ make -j8`
+
+## Flash firmware
+
+Enter fastboot mode. There are two options:
+- power off the board, turn ON dipswitch 1 and 3, power on the board.
+- connect the board via USB and run from host machine:
+  `$ adb reboot bootloader`
+Check if device has entered bootloader, run from host machine:
+  `fastboot devices`
+Flash device:
+  `$ cd device/linaro/hikey/installer/hikey960`
+  `$ ./flash-all.sh`
