-Finally we are ready to write our "Hello World" app.
-
-First we create a new edk2 module in our package directory similar to the our `SimplestApp` module:
-```
-$ mkdir UefiLessonsPkg/HelloWorld
-$ vi UefiLessonsPkg/HelloWorld/HelloWorld.inf
-[Defines]
-  INF_VERSION                    = 1.25
-  BASE_NAME                      = HelloWorld
-  FILE_GUID                      = 2e55fa38-f148-42d3-af90-1be247323e30
-  MODULE_TYPE                    = UEFI_APPLICATION
-  VERSION_STRING                 = 1.0
-  ENTRY_POINT                    = UefiMain
-
-[Sources]
-  HelloWorld.c
-
-[Packages]
-  MdePkg/MdePkg.dec
-
-[LibraryClasses]
-  UefiApplicationEntryPoint
-```
-Don't forget to add our newly created app to the `Components` section of the package DSC file
-```
-[Components]
-  UefiLessonsPkg/SimplestApp/SimplestApp.inf
-+ UefiLessonsPkg/HelloWorld/HelloWorld.inf
-```
-Next we need to write the source code file. Let's remember the code for our SimplestApp:
-```
-EFI_STATUS
-EFIAPI
-UefiMain (
-  IN EFI_HANDLE        ImageHandle,
-  IN EFI_SYSTEM_TABLE  *SystemTable
-  )
-{
-  return EFI_SUCCESS;
-}
-```
-To print something to the console ("Hello World" message in our case) we need to use services from the `EFI_SYSTEM_TABLE` that is passed to the entry point of our app.
-
-The description of the `EFI_SYSTEM_TABLE` can be found in the UEFI specification (https://uefi.org/sites/default/files/resources/UEFI_Spec_2_8_final.pdf).
-
-EFI_SYSTEM_TABLE is a struct that was populated by the UEFI firmware and contains pointers to the runtime and boot services tables.
-```
-typedef struct {
- EFI_TABLE_HEADER Hdr;
- CHAR16 *FirmwareVendor;
- UINT32 FirmwareRevision;
- EFI_HANDLE ConsoleInHandle;
- EFI_SIMPLE_TEXT_INPUT_PROTOCOL *ConIn;
- EFI_HANDLE ConsoleOutHandle;
- EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL *ConOut;
- EFI_HANDLE StandardErrorHandle;
- EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL *StdErr;
- EFI_RUNTIME_SERVICES *RuntimeServices;
- EFI_BOOT_SERVICES *BootServices;
- UINTN NumberOfTableEntries;
- EFI_CONFIGURATION_TABLE *ConfigurationTable;
-} EFI_SYSTEM_TABLE;
-```
-We are interested in the `ConOut` field. `ConOut` is abbreviaton for "Console Output" and according to the UEFI spec it is a pointer to the `EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL` interface that is associated with `ConsoleOutHandle`.
-
-If we keep digging into UEFI spec we can find description of the `EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL`.
-According to the spec `EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL` defines the minimum requirements for a text-based ConsoleOut device.
-
-As everything in UEFI it has GUID:
-```
-#define EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL_GUID \
- {0x387477c2,0x69c7,0x11d2,\
- {0x8e,0x39,0x00,0xa0,0xc9,0x69,0x72,0x3b}}
-```
-
-And the interface description is:
-```
-typedef struct _EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL {
- EFI_TEXT_RESET Reset;
- EFI_TEXT_STRING OutputString;
- EFI_TEXT_TEST_STRING TestString;
- EFI_TEXT_QUERY_MODE QueryMode;
- EFI_TEXT_SET_MODE SetMode;
- EFI_TEXT_SET_ATTRIBUTE SetAttribute;
- EFI_TEXT_CLEAR_SCREEN ClearScreen;
- EFI_TEXT_SET_CURSOR_POSITION SetCursorPosition;
- EFI_TEXT_ENABLE_CURSOR EnableCursor;
- SIMPLE_TEXT_OUTPUT_MODE *Mode;
-} EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL;
-```
-Right now we are interested in a `OutputString` method:
-```
-OutputString     Displays the string on the device at the current cursor location.
-```
-This is what we need. Let's look at the function description:
-```
-EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL.OutputString()
-
-Summary
-Writes a string to the output device.
-
-Prototype
-typedef
-EFI_STATUS
-(EFIAPI *EFI_TEXT_STRING) (
- IN EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL *This,
- IN CHAR16 *String
- );
-
-Parameters
-This    A pointer to the EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL instance.
-String  The Null-terminated string to be displayed on the output device(s).
-```
-
-In edk2 `EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL` is defined in the header file:
-https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Protocol/SimpleTextOut.h
-
-
-With all this knowledge we can write our source code file `UefiLessonsPkg/HelloWorld/HelloWorld.c`:
-```
-EFI_STATUS
-EFIAPI
-UefiMain (
-  IN EFI_HANDLE        ImageHandle,
-  IN EFI_SYSTEM_TABLE  *SystemTable
-  )
-{
-  SystemTable->ConOut->OutputString(SystemTable->ConOut, L"Hello World!\n");
-  return EFI_SUCCESS;
-}
-```
-
-The `L""` signifies that the string is composed from CHAR16 symbols, as was required in spec.
-
-Let's compile our edk2 module:
-```
-$ build --platform=UefiLessonsPkg/UefiLessonsPkg.dsc \
-        --module=UefiLessonsPkg/HelloWorld/HelloWorld.inf \
-        --arch=X64 \
-        --buildtarget=RELEASE --tagname=GCC5
-```
-
-Copy the app to our `UEFI_disk` folder and run OVMF:
-```
-$ cp Build/UefiLessonsPkg/RELEASE_GCC5/X64/HelloWorld.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
-```
-
