+
+## Building coreboot
+
+### Preliminaries
+
+Prior to building coreboot the following files are required:
+
+Comet Lake and Kaby Lake configurations:
+- Intel Flash Descriptor file (descriptor.bin)
+- Intel Management Engine firmware (me.bin)
+
+Comet Lake configuration only:
+- ITE IT8987E firmware (it8987-x.xx.bin)
+
+All Star Labs platforms:
+- 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:
+
+##### LabTop Mk IV (Comet Lake)
+
+```bash
+make distclean
+make defconfig KBUILD_DEFCONFIG=configs/config.starlabs_labtop_cml
+make
+```
+
+##### LabTop Mk III (Kaby Lake)
+
+```bash
+make distclean
+make defconfig KBUILD_DEFCONFIG=configs/config.starlabs_labtop_kbl
+make
+```
+
+## Flashing coreboot
+
+```eval_rst

+
+#### **Requirements:**
+
+* Only available on Star Labtop Mk IV and Star LabTop Mk III
+* fwupd version 1.5.6 or later
+* The battery must be charged to at least 30%
+* The charger must be connected (either USB-C or DC Jack)
+* BIOS Lock must be disabled
+* Supported Linux distribution (Ubuntu 20.04 +, Linux Mint 20.1 + elementaryOS 6 +, Manjaro 21+)
+
+**fwupd 1.5.6 or later**
+To check the version of **fwupd** you have installed, open a terminal window and enter the below command:
+
+```
+fwupdmgr --version
+```
+
+This will show the version number. **1.5.6** or greater will work.
+![fwupd version](https://cdn.shopify.com/s/files/1/2059/5897/files/fwupdV.png?v=1611136423)
+On Ubuntu 20.04, Ubuntu 20.10, Linux Mint 20.1 and elementaryOS 6, fwupd 1.5.6 can be installed from our PPA with the below terminal commands:
+
+```
+sudo add-apt-repository ppa:starlabs/ppa
+sudo apt update
+sudo apt install fwupd
+```
+
+On Manjaro:
+
+```
+sudo pacman -Sy fwupd-git flashrom-starlabs
+```
+
+Instructions for other distributions will be added once fwupd 1.5.6 is available. If you are not using one of the distributions listed above, it is possible to install coreboot using a Live USB.
+
+**Disable BIOS Lock**
+BIOS Lock must be disabled when switching from the standard AMI (American Megatrends Inc.) firmware to coreboot. To disable BIOS Lock:
+
+1\. Start with your LabTop turned off\. Turn it on whilst holding the **F2** key to access the BIOS settings.
+2\. When the BIOS settings load, use the arrow keys to navigate to the advanced tab\. Here you will see BIOS Lock\.
+3\. Press `Enter` to change this setting from **Enabled** to **Disabled**
+
+![Disable BIOS Lock](https://cdn.shopify.com/s/files/1/2059/5897/files/IMG_20210120_094049709_1.jpg?v=1611139567)
+
+4\. Next, press the `F10` key to **Save & Exit** and then `Enter` to confirm.
+
+#### **Switching Branch**
+
+Switching branch refers to changing from AMI firmware to coreboot, or vice versa.
+
+First, check for new firmware files with the below terminal command:
+
+```
+fwupdmgr refresh --force
+```
+
+Then, to change branch, enter the below terminal command:
+
+```
+fwupdmgr switch-branch
+```
+
+You can then select which branch you would like to use, by typing in the corresponding number:
+![Switch Branch](https://cdn.shopify.com/s/files/1/2059/5897/files/SwitchBranch.png?v=1611138496)
+You will be prompted to confirm, press `y` to continue or `n` to cancel.
+
+Once the switch has been completed, you will be prompted to restart.
+
+![Installed coreboot](https://cdn.shopify.com/s/files/1/2059/5897/files/Complete.png?v=1611138934)
+The next reboot can take up to **5 minutes,** do not interrupt this process or disconnect the charger. Once the reboot is complete, that's it - you'll continue to receive updates for whichever branch you are using.
+
+You can switch branch at any time. \ No newline at end of file
