+## Building coreboot
+
+### Preliminaries
+
+Prior to building coreboot the following files are required:
+* Intel Flash Descriptor file (descriptor.bin)
+* Intel Management Engine firmware (me.bin)
+* ITE Embedded Controller firmware (ec.bin)
+
+The files listed below are optional:
+- Splash screen image in Windows 3.1 BMP format (Logo.bmp)
+
+These files exist in the correct location in the StarLabsLtd/blobs repo on GitHub which is used in place of the standard 3rdparty/blobs repo.
+
+### Build
+
+The following commands will build a working image:
+
+```bash
+make distclean
+make defconfig KBUILD_DEFCONFIG=configs/config.starlabs_lite_glk
+make
+```
+
