+
+## Development
+
+Patches are merged by [EricS-Valve](https://github.com/EricS-Valve) from time to time, usually late in the day or on a weekend.
+
+The SDK game code and live TF2 are not identical. There is code in the SDK that is not present in TF2, and vice versa. For example, `NotificationQueue_Add` is [disabled in the SDK](https://github.com/ValveSoftware/source-sdk-2013/blob/9cbe7d5d3c847fb2e2be6049c3e2a72853bd6b85/src/game/client/econ/econ_notifications.cpp#L1292) but not in live TF2. Not to mention, Valve uses Perforce P4 for version control instead of Git.
+
+## Building with Visual Studio 2026
+
+Valve Project Creator (VPC) only targets up to Visual Studio 2022. Visual Studio 2026 can be used if you install the 2022 toolchain:
+```bat
+"C:\Program Files (x86)\Microsoft Visual Studio\Installer\setup.exe" modify --installPath "C:\Program Files\Microsoft Visual Studio\18\Community" ^
+    --add Microsoft.VisualStudio.Component.VC.14.44.17.14.x86.x64 ^
+    --add Microsoft.VisualStudio.Component.VC.14.44.17.14.MFC     ^
+    --add Microsoft.VisualStudio.Component.VC.14.44.17.14.ATL
+```
+
+You will need to install Python as well:
+```bat
+winget install Python.Python.3.14
+```
+
+After that, follow the build instructions in README.md.
+
+## Code style
+
+* Use tabs for indentation.
+* Use [hungarian notation](https://en.wikipedia.org/wiki/Hungarian_notation) for any variable that is serialized.
+* Curly braces get a new line. ([Allman style](https://en.wikipedia.org/wiki/Indentation_style#Allman_style))
+* Curly braces can be omitted if the condition body is only one line.
+* Pointer asterisks go on the right, next to the variable name.
+* Put spaces around function arguments.
+* Put spaces around template arguments. (Usually. The code base is like 60-40 in favor of this style.)
+
+All this being said, much of the code base is not consistent. Just pay attention to the surrounding code and match the style.
