+# AriaG25 / Terra board support
+
+Aria G25 is a cost-effective System-on-Module (SoM) thought of to drastically reduce the development time needed to design a low-power and low-EMI Linux Embedded device.
+
+Terra board is a complete hardware solution conceived to:
+
+* Evaluate the Aria G25 Linux embedded module for your own hardware design (schematic, bom, etc are available here)
+
+* Create concept prototypes using the Daisy add-on boards system for in-field applications
+
+* Build end-user products
+
+
+## AriaG25 Getting started
+
+To build a new minimal AriaG25 rootfs simply load corresponding ariag25_defconfig file. The config is fairly basic with only the kernel and busybox selected.
+
+To make the board bootable please follow the instruction on the producer website:
+
+[http://acmesystems.it/binary_repository](http://acmesystems.it/binary_repository)
+
+You will only need the correct boot.bin file for your board type, everithing else like kernel, dtb and roots are built by buildroot inside images directory.
+
+## Terra getting started
+
+To build a new minimal AriaG25 rootfs simply open the corresponding ariag25_demo_terra_defconfig file. This configuration is a bit more complete than the other and provides python, networking support and ssh access. It's meant to be usable as a reference for running example code you can find on the producer website:
+
+[http://acmesystems.it/tutorials](http://acmesystems.it/tutorials)
+
+Networking is configured for DHCP on the eth0.
+
+Please note that this configuration needs the correct boot.bin file, please refer to the AriaG25 getting started to know how to obtain it.
