+# Add Watchfaces 
+
+This page will help you to add a new Watch Face to InfiniTime.
+
+## Theory
+
+This example uses the existing Digital Watch Face, and copies it to a new watch face as a starting point.
+
+## Files 
+
+- displayapp/UserApps.h
+- displayapp/apps/Apps.h.in
+- displayapp/apps/CMakeLists.txt
+- displayapp/screens/WatchFaceNew.cpp 
+- displayapp/screens/WatchFaceNew.h 
+- CMakeLists.txt
+
+### Branch and Copy 
+
+Use git to fork and get a local copy (commands not shown). 
+
+Then with all the submodules updated add a branch and copy the watch face files
+
+```bash
+git submodule update --init
+git switch -c Watchface_New
+cp ./src/displayapp/screens/WatchFaceDigital.cpp ./src/displayapp/screens/WatchFaceNew.cpp
+cp ./src/displayapp/screens/WatchFaceDigital.h ./src/displayapp/screens/WatchFaceNew.h
+```
+
+### Amend Files
+
+Use sed to update `WatchFaceDigital` in the newly copied files with `WatchFaceNew` as well as update the `WatchFace::Digital` type to `WatchFace::NewType`.
+
+```bash
+sed -i 's/WatchFaceDigital/WatchFaceNew/' src/displayapp/screens/WatchFaceNew.cpp src/displayapp/screens/WatchFaceNew.h
+sed -i 's/WatchFace::Digital/WatchFace::NewType/' src/displayapp/screens/WatchFaceNew.h
+```
+
+In UserApps.h add include for the new Watch Face.
+
+./src/displayapp/UserApps.h:
+
+```cpp
+...
+#include "displayapp/screens/WatchFaceNew.h"
+```
+
+In Apps.h.in add the type from WatchFaceNew.h.
+
+./src/displayapp/apps/Apps.h.in:
+
+```cpp
+enum class WatchFace : uint8_t {
+...
+CasioStyleG7710,
+NewType,
+```
+
+In CMakeLists.txt add the type to the DEFAULT_WATCHFACE_TYPES so that it is included in the firmware.
+
+./src/displayapp/apps/CMakeLists.txt:
+
+```cmake
+...
+set(DEFAULT_WATCHFACE_TYPES "${DEFAULT_WATCHFACE_TYPES}, WatchFace::CasioStyleG7710")
+set(DEFAULT_WATCHFACE_TYPES "${DEFAULT_WATCHFACE_TYPES}, WatchFace::NewType")
+```
+
+In CMakeLists.txt include the WatchFaceNew.cpp source file.
+
+./src/CMakeLists.txt:
+
+```cpp
+...
+displayapp/screens/WatchFacePineTimeStyle.cpp
+displayapp/screens/WatchFaceCasioStyleG7710.cpp
+displayapp/screens/WatchFaceNew.cpp
+```
+
+## Test Copied Watch Face
+
+At this point - assuming you have [InfiniTime simulator](https://github.com/InfiniTimeOrg/InfiniSim) locally installed. It is a good time to test. 
+
+If you already have a `build/CMakeCache.txt` it will prevent your new watch face from being included in the build, so you will need to pass the `--fresh` argument to `cmake` or remove `build/CMakeCache.txt` before building. (The value of DEFAULT_WATCHFACE_TYPES is cached.)
+
+## Amending the Watch Face to Suit 
+
+Start editing and ammended WatchFaceNew.cpp to suit your tastes. To save space on the firmware, use existing fonts. 
+
+## Finish
+
+You should now be able to [build](../buildAndProgram.md) the firmware
+and flash it to your PineTime. Yay!
+
+Please remember to pay attention to the [UI guidelines](../ui_guidelines.md)
+when designing an app or Watch Face that you want to be included in InfiniTime.
