 ## Software
-Developers can use C/C++/Python as well as (or in conjunction with) GNU Radio flowgraphs. Tools such as gcc are built-in. The experimental Linux image is available [here](https://m17project.org/linht/).
-
-Instructions for setting up the Yocto build environment can be found in the [M17 Wiki](https://wiki.m17foundation.org/index.php?title=LinHT_Image_Build).
-
-All layers required to build the image are located in the M17 Project GitHub:
-
-- [meta-linht-hardware](https://github.com/M17-Project/meta-linht-hardware): Provides machine configuration and hardware support for the LinHT hardware.
-- [meta-linht-software](https://github.com/M17-Project/meta-linht-software): Provides application software, libraries, and system configuration for digital radio communication and M17 protocol support.
-- [meta-linht-sdr](https://github.com/M17-Project/meta-linht-sdr): A modified version of [meta-sdr](https://github.com/balister/meta-sdr), providing the GNU Radio package.

+### Flashing
+
+To flash the images to LinHT the [Universal Update Utility](https://github.com/nxp-imx/mfgtools/releases) is needed.
+LinHT needs to be booted into flash mode (holding the secondary side button while booting).
+Once in flash mode, the image can be written with uuu:
+```bash
+uuu -v -b emmc_all imx-boot-mcm-imx93-sd.bin-flash_singleboot linht-image-mcm-imx93.rootfs.wic.zst
+```
+
+## Driver
+
+To access LinHTs network device under windows, [RNDIS driver](https://www.catalog.update.microsoft.com/Search.aspx?q=USB%20RNDIS%20Gadget) need to be installed.
