+# Guide to Codebase Change Markers
+
+Whenever you change a file not owned by this codebase you need to clarify which portions have been changed. If the markers described below don't have a description for the file type you're working with, don't add a marker yet and ask a reviewer if you need one and how it should be done.
+
+The following is the formatting for annotations per language type:
+
+
+### C#
+
+Single line changes:
+
+```csharp
+<Rest of the unchanged file above...>
+[Your code here. This can be entirely original or modified from the original file] // Parkstation-[TitleOfFeature] - Optional clarification of change
+<Rest of the unchanged file below...>
+```
+
+Multiple line changes:
+
+```csharp
+<Rest of the unchanged file above...>
+// Parkstation-[TitleOfFeature]-Start - Optional clarification of change
+[Your code here. This can be entirely original or modified from the original file]
+// Parkstation-[TitleOfFeature]-End
+<Rest of the unchanged file below...>
+```
+
+
+### XAML
+
+Single line changes:
+
+```xaml
+<Rest of the unchanged file above...>
+<!-- Parkstation-[TitleOfFeature] - Optional clarification of change -->
+[Your code here. This can be entirely original, or modified from the original file]
+<Rest of the unchanged file below...>
+```
+
+Multiple line changes:
+
+```xaml
+<Rest of the unchanged file above...>
+<!-- Parkstation-[TitleOfFeature]-Start - Optional clarification of change -->
+[Your code here. This can be entirely original, or modified from the original file]
+<!-- Parkstation-[TitleOfFeature]-End -->
+<Rest of the unchanged file below...>
+```
+
+
+
+### YML
+
+Single line changes:
+
+```yml
+<Rest of the unchanged file above...>
+[Your code here. This can be entirely original, or modified from the original file] # Parkstation-[TitleOfFeature] - Optional clarification of change
+<Rest of the unchanged file below...>
+```
+
+Multiple line changes:
+
+```yml
+<Rest of the unchanged file above...>
+# Parkstation-[TitleOfFeature]-Start - Optional clarification of change
+[Your code here. This can be entirely original, or modified from the original file]
+# Parkstation-[TitleOfFeature]-End
+<Rest of the unchanged file below...>
+```
