-# LightningBolt
-
-A (only semi-WIP) extractor for The Simpsons Skateboarding BOLT archive files.
-
-Currently only works with US copies.
-
-# Building
-
-You need:
-
-- CMake
-- A C++20 compiler (clang/gcc, MSVC won't work on Windows, you need clang-cl)
-
-```bash
-$ cmake -GNinja -Bbuild -DCMAKE_BUILD_TYPE=Release
-$ cmake --build build
-```
-
-# Using
-
-Run `lightningbolt` where both the game executable and ASSETS.BLT reside.
