 The `build-kernel.sh` script requires an installed Golang version matching the
 [component build requirements](https://github.com/kata-containers/documentation/blob/master/Developer-Guide.md#requirements-to-build-individual-components).
 
+## Usage
+
+```
+$ ./build-kernel.sh -h
+Overview:
+
+	Build a kernel for Kata Containers
+
+Description: This script is the *ONLY* to build a kernel for development.
+
+
+Usage:
+
+	build-kernel.sh [options] <command> <argument>
+
+Commands:
+
+- setup
+
+- build
+
+- install
+
+Options:
+
+	-c <path>   : Path to config file to build a the kernel.
+	-d          : Enable bash debug.
+	-e          : Enable experimental kernel.
+	-f          : Enable force generate config when setup.
+	-g <vendor> : GPU vendor, intel or nvidia.
+	-h          : Display this help.
+	-k <path>   : Path to kernel to build.
+	-p <path>   : Path to a directory with patches to apply to kernel.
+	-t          : Hypervisor_target.
+	-v          : Kernel version to use if kernel path not provided.
+```
+
+Example:
+```
+$ ./build-kernel.sh -v 4.19.86 -g nvidia -f -d setup
+```
+> **Note**
+> - `-v 4.19.86`: Specify the guest kernel version.
+> - `-g nvidia`: To build a guest kernel supporting Nvidia GPU.
+> - `-f`: The .config file is forced to be generated even if the kernel directory already exists.
+> - `-d`: Enable bash debug mode.
