+### SLC
+
+TL;DR — Code in this repository emulates [SLGetWindowsInformationDWORD](https://learn.microsoft.com/en-us/windows/win32/api/slpublic/nf-slpublic-slgetwindowsinformationdword) API from `SLC.DLL` with a singular purpose — to enable playing original [Microsoft FreeCell](https://en.wikipedia.org/wiki/Microsoft_FreeCell) and [Microsoft Minesweeper](https://en.wikipedia.org/wiki/Microsoft_Minesweeper) games from Microsoft Windows 7 on a modern Microsoft Windows operating systems such as Microsoft Windows 10 and Microsoft Windows 11.
+
+**DISCLAIIMER:**
+
+This code was written for educational purposes only, with a sole goal of gaming history preservation.
+
+It can only be used to bypass the enablement check for those two specific games which must be acquired legally (i.e. you must own a valid Microsoft Windows 7 product key and installation media).
+
+It is provided as a way to avoid having to run fully virtualized Microsoft Windows 7 operating system in order to run those games today.
+
+The author does not condone licensing circumvention nor piracy and cannot be held responsbile for your eventual misuse of their code.
+
+By obtaining and compiling this code or by downloading prebuilt DLLs from the Releases page you are taking full responsibility for your own actions.
