+# Introduction
+
+This branch is used to develop the **Capsule-On-Disk** feature.

+
+# Feature Summary
+
+Traditionally capsule image is delivered to BIOS in persistent memory across system reset, but not all platforms support or function well across memory persistent reset. To solve this problem, **Capsule-On-Disk** delivers capsule images through EFI system partition on peripheral storage device. For security reasons, Design is composed of 2 solutions.
+- **Solution A)** - Load the image out of TCB and rely on Capsule-In-RAM to deliver Capsule-On-Disk.
+- **Solution B)** - Relocate capsule image outside TCB. And leverage existing storage stack in PEI to load all capsule on disk images. Solution B) has bigger TCB but can work without Capsule-In-RAM support
+
+>User can test this feature with **CapsuleApp** in **MdeModulePkg**. It has been updated to support Capsule on Disk since **2019 Q1 stable release**.
+
+Brief working flow of  **Capsule-On-Disk**:
+```
+1. Store capsule images into \EFI\Capsules\ folder on EFI system partition.
+2. Set EFI_OS_INDICATIONS_FILE_CAPSULE_DELIVERY_SUPPORTED flag in L"OsIndications".
+3. Reboot system.
+4. Get all capsule images from \EFI\Capsules\ after TCB, relocated them to root direcotry of a platform-specific NV storage device with BlockIo protocol.
+5. Reboot system.
+6. Load capsule imaages from the root direcotry in TCB, and build CV hobs
+```

Due to the tight schedule, we plan to upstream code to staging earlier if there is no more comments. The due date will change to Apr 16th.
You can continue to evaluate the feature and provide feedback when this feature stays in staging.

BR,
Wei Xu

Wei Xu,

Thanks for providing this request for a new edk2-staging branch.

Please add the branch maintainers to the Readme along with the criteria that must be met for the feature to be considered a candidate for edk2/master.

With those updates, Reviewed-by: Michael D Kinney michael.d.kinney@intel.com<mailto:michael.d.kinney@intel.com>

Thanks,

Mike
