+## Proof of Concept
+The proof of concept included in the project is the `Main.c` file. This can be
+compiled into a `ReflectiveUnloader.dll` which is compartible with
+[Reflective DLL Injection][1]. The resulting executable can then be injected
+into an arbitrary process (assuming premissions and architecture constraints are
+met) with the [inject.exe][4] utility. Take note of the hash of the DLL file
+before proceeding. See the [releases page][5] for pre-built binaries.
+
+Once the DLL is injected into a process, it will display a message box. This is
+used to present the user with an opportunity to delete the original DLL from
+disk. After the message box is closed, a new and identical copy will be written
+to `%USERPROFILE%\\Desktop\\ReflectiveUnloader.dll`.
+
+Finally the user can compare the hashes of the two files to determine that they
+are identical.
