+# Giants Wdefs Importer
+
+This tool was created to simplify the process of importing custom Wdefs for Giants 1.502.1.
+
+![Image](readme-img/screenshot.png)
+
+## What it does
+
+This tool:
+   1. Creates a backup of your game.
+   2. Downloads the requested wdefs file.
+   3. Modifies GiantsMain.exe to overwrite the expected CRC value (the game won't load if there is a CRC mismatch).
+   4. Starts modded Giants.
+   5. Reverts everything to original state after Giants is closed.
+
+## Where to find modded wdefs?
+
+[Check our Discord server](https://discord.gg/Avj4azU)
+
+## What about cheaters?
+
+Starting 1.497, Giants features a built-in anti-cheat. It works by automatically detecting mismatching clients and kicking them if they don't use the same environment as the server.
