+## Windows Notes
+Project was built under the CMake directives using Visual Studio 2022 using:
+
+    Build > Build All
+
+No errors occurred and project was built successfully
+
+web_server.cpp is included so CMake does not break
+
+proxy.cpp and network.hpp are all that are needed (one .cpp and one .h file)
+
+CMake compiles into the "out" folder using Visual Studio 2022
+
+    Ex: {Project_Root}\out\build\x64-Debug\bin\proxy.exe
