+Mullvad notes for creating an NSIS plug-in
+==
+
+Using `Visual Studio`, create a new DLL project.
+
+Remove the x64 build configurations. Do this both for the solution and the project. 
+  AMD64 support is spotty in NSIS and may not be supported at all when using NSIS via electron-builder.
+
+Update `targetver.h` with an appropriate value for `_WIN32_WINNT`.
+
+Disable /SafeSEH (it's under Linker -> Advanced).
+
+Add the parent of the plugin SDK folder as an include directory for header files (it's under C/C++ -> General).
+
+Add the plugin SDK folder as an include directory for linker libraries (it's under Linker -> General).
+
+Add `pluginapi-x86-unicode.lib` to the set of linker libraries (it's under Linker -> Input).
+
+Add `libc.lib` as an ignored linker library. `pluginapi-x86-unicode.lib` has a reference to `libc.lib`, which is
+  apparently not needed. The setting is under Linker -> Input.
+
+Change to static CRT linkage for the Release configuration (it's under C/C++ -> Code Generation).
