> > > - These tools streamline the process of packaging firmware updates into a format that can be deployed and applied to the device hardware.
> > > - The tools can be run on both Linux and Windows environments, providing flexibility for different development setups.
> > > - By using OpenSSL for certificate generation and signing, the tools ensure that the firmware updates are secure and authenticated. To set up the capsule, see the [Capsule generation in UEFI](https://docs.qualcomm.com/doc/80-70030-4/topic/capsule-generation-in-uefi.html#generate-the-capsule).
