-In the last lesson to build our app we've included its *.inf file as a component to the other package and have built this package. It is clearly not a good solution and in this lesson we will create our own package.
-
-First lets remove our app from the `OvmfPkg/OvmfPkgX64.dsc` file:
-```
- ################################################################################
- [Components]
--  SimplestApp/SimplestApp.inf
-   OvmfPkg/ResetVector/ResetVector.inf
-
-```
-
-Then create `UefiLessonsPkg` folder in the edk2 directory and move our app into this folder:
-```
-mkdir UefiLessonsPkg
-mv SimplestApp UefiLessonsPkg/SimplestApp
-```
-
-Then we need to create platform description file (DSC) for our newly created package:
-```
-$ vi UefiLessonsPkg/UefiLessonsPkg.dsc
-[Defines]
-  DSC_SPECIFICATION              = 0x0001001C
-  PLATFORM_GUID                  = 3db7270f-ffac-4139-90a4-0ae68f3f8167
-  PLATFORM_VERSION               = 0.01
-  PLATFORM_NAME                  = UefiLessonsPkg
-  SKUID_IDENTIFIER               = DEFAULT
-  SUPPORTED_ARCHITECTURES        = X64
-  BUILD_TARGETS                  = RELEASE
-
-[Components]
-  UefiLessonsPkg/SimplestApp/SimplestApp.inf
-```
-All the fileds under `Defines` section are mondatory.
-Full specification for the Platform Description (DSC) File can be found under https://edk2-docs.gitbook.io/edk-ii-dsc-specification/
-
-Let's try to build our SimplestApp module that is now in our own package:
-```
-$ . edksetup.sh
-$ build --platform=UefiLessonsPkg/UefiLessonsPkg.dsc \
-        --module=UefiLessonsPkg/SimplestApp/SimplestApp.inf \
-        --arch=X64 \
-        --buildtarget=RELEASE \
-        --tagname=GCC5
-```
-
-Unfortunately the build would fail:
-```
-build.py...
-/home/kostr/edk2/UefiLessonsPkg/UefiLessonsPkg.dsc(...): error 4000: Instance of library class [UefiApplicationEntryPoint] is not found
-        in [/home/kostr/edk2/UefiLessonsPkg/SimplestApp/SimplestApp.inf] [X64]
-        consumed by module [/home/kostr/edk2/UefiLessonsPkg/SimplestApp/SimplestApp.inf]
-```
-
-To fix this we need to add `UefiApplicationEntryPoint` to the `LibraryClasses` section in our `UefiLessonsPkg.dsc` file.
-To find necessay include lets search our edk2 codebase:
-```
-$ grep UefiApplicationEntryPoint -r ./ --include=*.inf | grep LIBRARY_CLASS
-./MdePkg/Library/UefiApplicationEntryPoint/UefiApplicationEntryPoint.inf:  LIBRARY_CLASS                  = UefiApplicationEntryPoint|UEFI_APPLICATION
-```
-
-Therefore we need to add these strings to our *.dsc file:
-```
-[LibraryClasses]
-  UefiApplicationEntryPoint|MdePkg/Library/UefiApplicationEntryPoint/UefiApplicationEntryPoint.inf
-```
-Format of the record is
-```
-LibraryClassName|Path/To/LibInstanceName.inf
-```
-LibraryClass can have several potential realizations (instances), therefore we need to write both `LibraryClassName` and `LibraryInstanceName`.
-
-In the end this adds this string to the Makefile:
-```
-LIBS = $(LIBS) $(LIB_DIR)/$(LibInstanceName)
-```
-You can read more about `LibraryClasses` section under https://edk2-docs.gitbook.io/edk-ii-dsc-specification/2_dsc_overview/26_-libraryclasses-_section_processing
-
-Let's try to rebuild:
-```
-$ build --platform=UefiLessonsPkg/UefiLessonsPkg.dsc \
-        --module=UefiLessonsPkg/SimplestApp/SimplestApp.inf \
-        --arch=X64 \
-        --buildtarget=RELEASE \
-        --tagname=GCC5
-```
-
-But the build would fail again:
-```
-build.py...
-/home/kostr/tiano/edk2/UefiLessonsPkg/UefiLessonsPkg.dsc(...): error 4000: Instance of library class [UefiBootServicesTableLib] is not found
-        in [/home/kostr/tiano/edk2/MdePkg/Library/UefiApplicationEntryPoint/UefiApplicationEntryPoint.inf] [X64]
-        consumed by module [/home/kostr/tiano/edk2/UefiLessonsPkg/SimplestApp/SimplestApp.inf]
-```
-
-As we see the error message is the same. It seems like `UefiApplicationEntryPoint` module that we've included needs some additional includes. So we search necessary libraries again... and again... and again.
-In the end our *.dsc file would be looking like this:
-```
-[Defines]
-  PLATFORM_NAME                  = UefiLessonsPkg
-  PLATFORM_GUID                  = 3db7270f-ffac-4139-90a4-0ae68f3f8167
-  PLATFORM_VERSION               = 0.01
-  DSC_SPECIFICATION              = 0x00010006
-  OUTPUT_DIRECTORY               = Build/UefiLessonsPkg
-  SUPPORTED_ARCHITECTURES        = X64
-  BUILD_TARGETS                  = RELEASE
-  SKUID_IDENTIFIER               = DEFAULT
-
-[LibraryClasses]
-  UefiApplicationEntryPoint|MdePkg/Library/UefiApplicationEntryPoint/UefiApplicationEntryPoint.inf
-  UefiBootServicesTableLib|MdePkg/Library/UefiBootServicesTableLib/UefiBootServicesTableLib.inf
-  DebugLib|MdePkg/Library/UefiDebugLibConOut/UefiDebugLibConOut.inf
-  BaseLib|MdePkg/Library/BaseLib/BaseLib.inf
-  PcdLib|MdePkg/Library/BasePcdLibNull/BasePcdLibNull.inf
-  BaseMemoryLib|MdePkg/Library/BaseMemoryLib/BaseMemoryLib.inf
-  RegisterFilterLib|MdePkg/Library/RegisterFilterLibNull/RegisterFilterLibNull.inf
-  PrintLib|MdePkg/Library/BasePrintLib/BasePrintLib.inf
-  DebugPrintErrorLevelLib|MdePkg/Library/BaseDebugPrintErrorLevelLib/BaseDebugPrintErrorLevelLib.inf
-
-[Components]
-  UefiLessonsPkg/SimplestApp/SimplestApp.inf
-```
-
-After the successful build the result binary would be in a `Build/UefiLessonsPkg/RELEASE_GCC5/X64` folder:
-```
-$ ls -lh Build/UefiLessonsPkg/RELEASE_GCC5/X64/SimplestApp.efi
--rw-r--r-- 1 kostr kostr 960 Jun 13 12:47 Build/UefiLessonsPkg/RELEASE_GCC5/X64/SimplestApp.efi
-```
-
-Let's copy in our `UEFI_disk` folder and run it in OVMF:
-```
-$ cp Build/UefiLessonsPkg/RELEASE_GCC5/X64/SimplestApp.efi ~/UEFI_disk/
-$ qemu-system-x86_64 -drive if=pflash,format=raw,file=Build/OvmfX64/RELEASE_GCC5/FV/OVMF.fd \
-                     -drive format=raw,file=fat:rw:~/UEFI_disk \
-                     -nographic \
-                     -net none
-```
-
-Hopefully everything would be the same it was earlier:
-```

-UEFI v2.70 (EDK II, 0x00010000)
