I've created a README file for your Splinter Cell: Conviction — E3-Inspired Mod for Mark and Execute, credited to floydier world productions.

Installation: drag the "src" folder (which is in this .rar) into:

D:\SteamLibrary\steamapps\common\Tom Clancy's Splinter Cell Conviction

What's included
Mod description: Explains the goal of bringing selected features closer to the 2009 E3 demonstration.
Current development status: Covers Mark & Execute weapon tuning, camera zoom investigation, and future research.
Installation and safety notes: Advises users to back up original game files.
Copyright notice: © 2026 floydier world productions.
Permission terms: Allows personal, non-commercial use and modification while requiring credit to be retained.
Disclaimer: Clarifies that this is an unofficial fan project and is not affiliated with Ubisoft.

Note: The README distinguishes confirmed research from experimental features, so it doesn't promise that the camera changes or other E3-inspired features already work.
