+## Plasma Phone Reference System
+
+Recommended Device: **Nexus 5X (bullhead), Nexus 5 (hammerhead)**
+
+Needed software tools: **adb, fastboot**
+
+If you flash Plasma Mobile for the first time, you likely need to follow
+steps 1A and 1B.
+After successfully done those steps, you can always jump straight to
+step 2 for future flashing.
+
+### 1A. Unlock (skip if already unlocked)
+
+Unlock the Nexus 5:
+<https://www.androidpit.com/how-to-unlock-nexus-5-bootloader>
+Unlock the Nexus 5X:
+<https://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930>
+
+### 1B. Put into firmware mode and run once:
+
+**CAUTION: This will erase the complete memory of your Nexus 5 device!
+Please ensure you have a backup of all your data before you proceed.**
+
+    $ fastboot format cache 
+    $ fastboot format userdata
+
+### 2. Flashing Plasma Mobile (PM)
+
+Put your Nexus 5/X in fastboot mode (press volume down + power button
+at once), then open a terminal and run
+
+    $ git clone https://github.com/plasma-phone-packaging/pm-flashtool.git
+    $ cd pm-flashtool
+    $ ./pm-flash
+
+The -c parameter of script can be used to re-use the **cache** instead
+of downloading all the files again.
+
+The -p ***platform*** parameter currently accepts ***neon*** or
+***arch***
+
+It will download all files required and store them in cache subdir, e.g.
+for Nexus 5X (*bullhead)*:
+
+-   pm-rootfs-20161025-140532.tar.gz (Plasma Mobile in an LXC container)
+-   recovery.img (TWRP recovery img)
+-   system.img (AOSP system img)
+-   boot.img (AOSP boot img)
+
+Then the TWRP Recovery img is used as a tool to flash all other
+components to the target device.
+
+Note: The above could take quite some time (15-20 minutes) and require
+to enter your password to continue.
+
+### After Flashing is done
+
+If successfull, you should automatically see the Login Screen.
+The password to unlock is ‘1234’.
+
+(the username to enter the login prompt for your phone from an adb shell
+desktop terminal is ‘phablet’, password is ‘1234’).
