+### Preparing the image
+
+First, run the following script to prepare the binaries for the image:
+```bash
+./scripts/build-deps.sh
+```
+
+This will download and build the necessary dependencies for the kernel and put them
+into the `build` directory.
+
+Once that is done, you can create the image using the following command:
+```bash
+sudo ./scripts/create-image.sh
+```
+
+This will create an image file named `moss.img` in the root directory of the project,
+format it as VFAT 32 and create the necessary files and directories for the kernel.
+
+This script needs to run with sudo to mount the image through a loop device,
+which is required to properly create the image for the kernel to work.
