+## Brief overview
+  Guidelines for organizing builds in TIC-80, specifying the standard location for build artifacts to maintain consistency across different build types.
+
+## Build Location
+  - Always build projects in the 'build' folder to keep build artifacts organized and avoid cluttering the source directory.
+
+## Project-Specific Notes
+  - Applies to all TIC-80 build configurations, including SDL, Sokol, and Emscripten builds.

+## Brief overview
+  Guidelines for building TIC-80 with Emscripten support, ensuring proper configuration for web deployment with IDBFS.
+
+## Emscripten Configuration
+  - Use `emcmake cmake -G Ninja .. --fresh` to configure the build for Emscripten, ensuring a clean and proper setup for cross-compilation.
+
+## Project-Specific Notes
+  - This rule applies to TIC-80 projects requiring Emscripten builds for web platforms.
