+In this lesson we would look at another method how your application can publish HII String packages. This time we would talk about embedding HII data in the resulting EFI file PE/COFF resources.
+
+# Create application
+
+As usual create new application:
+```
+./createNewApp.sh HIIStringsUNIRC
+```
+
+Add it to our DSC package file UefiLessonsPkg/UefiLessonsPkg.dsc:
+```
+[Components]
+  ...
+  UefiLessonsPkg/HIIStringsUNI/HIIStringsUNI.inf
+```
+
+As last time, we would need a GUID for our package list, declare it in package DEC file UefiLessonsPkg/UefiLessonsPkg.dec:
+```
+[Guids]
+  ...
+  gHIIStringsUNIRCGuid = { 0x785693b4, 0x623e, 0x40fa, { 0x9a, 0x45, 0x68, 0xda, 0x38, 0x30, 0x89, 0xdd }}
+```
+
+Now modify application files to be similar to the `HIIStringsUNI` app. You'll need to create `Strings.uni` file and modify application INF and *.c file:
+- `UefiLessonsPkg/HIIStringsUNIRC/HIIStringsUNIRC.inf`
+- `UefiLessonsPkg/HIIStringsUNIRC/HIIStringsUNIRC.c`
+- `UefiLessonsPkg/HIIStringsUNIRC/Strings.uni`
+
+In the end you should have the same result as the `HIIStringsUNI` app:
+```
+FS0:\> HIIStringsUNIRC.efi
+en-US ID=1: English
+en-US ID=2: Hello!
+en-US ID=3: Bye!
+fr-FR ID=1: Francais
+fr-FR ID=2: Bonjour!
+fr-FR ID=3: Au revoir!
+Best language ID=1: English
+Best language ID=2: Hello!
+Best language ID=3: Bye!
+fr ID=3: Au revoir!
+```
+
+Now we'are ready for modifications.
+
+# UEFI_HII_RESOURCE_SECTION
+
+Add this to the `UefiLessonsPkg/HIIStringsUNIRC/HIIStringsUNIRC.inf`:
+```
+[Defines]
+  ...
+  UEFI_HII_RESOURCE_SECTION      = TRUE
+```
+
+`UEFI_HII_RESOURCE_SECTION` flag specifies whether HII resource section is generated into PE image.
+
+Now you wouldn't be able to build our application because of the error:
+```
+UefiLessonsPkg/HIIStringsUNIRC/HIIStringsUNIRC.c:15:42: error: ‘HIIStringsUNIRCStrings’ undeclared (first use in this function);
+```
+
+If you'll look at the `Build/UefiLessonsPkg/RELEASE_GCC5/X64/UefiLessonsPkg/HIIStringsUNIRC/HIIStringsUNIRC/DEBUG/HIIStringsUNIRCStrDefs.h` you'll see that this file still contains string tokens, but the `HIIStringsUNIRCStrings` is no longer here:
+
+And `AutoGen.c` file no longer contains `HIIStringsUNIRCStrings` array initialization code (`Build/UefiLessonsPkg/RELEASE_GCC5/X64/UefiLessonsPkg/HIIStringsUNIRC/HIIStringsUNIRC/DEBUG/AutoGen.c`).
+
+Now our strings directly encoded into the special section of the resulting *.efi image.
+
+To get them we need to search for a protocol `EFI_HII_PACKAGE_LIST_PROTOCOL` in the application `EFI_HANDLE ImageHandle`. 
+
+Here is relevant content from UEFI specification for the `EFI_BOOT_SERVICES.LoadImage()` function which shell uses to load every program:
+```
+Once the image is loaded, LoadImage() installs EFI_HII_PACKAGE_LIST_PROTOCOL on the handle if
+the image contains a custom PE/COFF resource with the type 'HII'. The protocol's interface pointer points
+to the HII package list which is contained in the resource's data
+```
+
+The `EFI_HII_PACKAGE_LIST_PROTOCOL` is identified by the `gEfiHiiPackageListProtocolGuid` from the https://github.com/tianocore/edk2/blob/master/MdePkg/MdePkg.dec:
+```
+[Protocols]
+  ...
+  ## Include/Protocol/HiiPackageList.h
+  gEfiHiiPackageListProtocolGuid  = { 0x6a1ee763, 0xd47a, 0x43b4, {0xaa, 0xbe, 0xef, 0x1d, 0xe2, 0xab, 0x56, 0xfc}}
+```
+
+As we already have `MdeModulePkg/MdeModulePkg.dec` in the `[Packages]` section of our INF file, all we need to do is add this GUID to the `[Protocols]` section:
+```
+[Protocols]
+  gEfiHiiPackageListProtocolGuid
+```
+
+In the code we could aquire `PackageList` protocol from the application `ImageHandle` with a help of `OpenProtocol` UEFI boot service:
+```
+...
+
+EFI_STATUS
+EFIAPI
+UefiMain (
+  IN EFI_HANDLE        ImageHandle,
+  IN EFI_SYSTEM_TABLE  *SystemTable
+  )
+{
+  EFI_STATUS Status;
+  EFI_HII_PACKAGE_LIST_HEADER *PackageList;
+  //
+  // Retrieve HII package list from ImageHandle.
+  //
+  Status = gBS->OpenProtocol (
+                  ImageHandle,
+                  &gEfiHiiPackageListProtocolGuid,
+                  (VOID **)&PackageList,
+                  ImageHandle,
+                  NULL,
+                  EFI_OPEN_PROTOCOL_GET_PROTOCOL
+                  );
+  if (EFI_ERROR (Status)) {
+    Print(L"Error! Can't open EFI_HII_PACKAGE_LIST_PROTOCOL\n");
+    return Status;
+  }
+  ...
+```
+
+The resulting `PackageList` is not only String packages with some size header from the `StrGather` script like in was in the case of `HIIStringsUNI` application. It is an ordinary Package list like the one that we've manually constructed in our `HIIStringsC` application.
+So instead of using `HiiAddPackages` library function we need to use `EFI_HII_DATABASE_PROTOCOL.NewPackageList()` directly:
+```
+EFI_HII_HANDLE Handle;
+Status = gHiiDatabase->NewPackageList(gHiiDatabase, PackageList, NULL, &Handle);
+if (EFI_ERROR(Status))
+{
+  Print(L"Can't register HII Package list %g, status = %r\n", gHIIStringsUNIRCGuid, Status);
+  return Status;
+}
+```
+
+Here I've used `gHiiDatabase`, so don't forget to add necessary header ```#include <Library/UefiHiiServicesLib.h>```and add `UefiHiiServicesLib` to the Library classes in the application INF file:
+```
+[LibraryClasses]
+  ...
+  UefiHiiServicesLib
+```
+
+Now you can build and verify that everything is ok:
+```
+FS0:\> HIIStringsUNIRC.efi
+Status = Success
+en-US ID=1: English
+en-US ID=2: Hello!
+en-US ID=3: Bye!
+fr-FR ID=1: Francais

+fr-FR ID=3: Au revoir!
+Best language ID=1: English
+Best language ID=2: Hello!
+Best language ID=3: Bye!
+fr ID=3: Au revoir!
+```
+
+# PE/COFF resource with the type 'HII'
+
+Let's use `objdump` utility to look at the application headers. You can output content of all headers with the `-x` option:
+```
+objdump -x  Build/UefiLessonsPkg/RELEASE_GCC5/X64/HIIStringsUNIRC.efi
+```
+
+Pay attention to these things:
