+## To install:
+
+1. Install [Arduino](https://www.arduino.cc/en/Main/Software)
+
+1. Install U8glib
+    * `Sketch` -> `Include Library` -> `Manage Libraries...`
+    * Search for and install `U8glib` by oliver
+
+1. Install Sanguino
+    * `File` -> `Preferences`
+    * Add
+    `https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json`
+    to `Additional Boards Manager URLs`
+
+1. Modify Sanguino `boards.txt`
+    * Close Arduino
+    * Locate Arduino15 folder
+        - `C:\Users\<username>\AppData\Local\Arduino15` for Windows
+        - `~/.arduino15` for Linux
+
+    * Locate `boards.txt` in `packages/Sanguino/hardware/avr/1.0.2`
+    (version number may change)
+    * Add the following to the end of `boards.txt`
+    (note that it is the same as sanguino.menu.cpu.atmega1284p but with
+    a different name and upload speed)
+
+            ## Malyan M150 W/ ATmega1284P 16MHz
+            sanguino.menu.cpu.malyan_m150=Malyan M150
+            sanguino.menu.cpu.malyan_m150.upload.maximum_size=130048
+            sanguino.menu.cpu.malyan_m150.upload.maximum_data_size=16384
+            sanguino.menu.cpu.malyan_m150.upload.speed=57600
+            sanguino.menu.cpu.malyan_m150.bootloader.file=optiboot/optiboot_atmega1284p.hex
+            sanguino.menu.cpu.malyan_m150.build.mcu=atmega1284p
+            sanguino.menu.cpu.malyan_m150.build.f_cpu=16000000L
+
+1. Configure Marlin
+    * Copy `_Bootscreen.h`, `Configuration.h`, and `Configuration_adv.h`
+    from `Marlin/config/examples/Malyan/M150` to `Marlin`
+    (overwrite files)
+    * Read `Configuration.h` and make any necessary changes
+
+1. Flash Marlin
+    * Turn on printer while pressing scroll wheel button
+    * Plug printer in to computer with USB cable
+    * Open `Marlin/Marlin.ino` with Arduino
+    * Configure Arduino
+        - `Tools` -> `Board` -> `Sanguino`
+        - `Tools` -> `Processor` -> `Malyan M150`
+        - `Tools` -> `Port` -> Select your port
+
+    * `Sketch` -> `Upload` or click arrow in top right corner
