+# AGENTS.md
+
+## Project Overview
+This is a game engine developed using a QuickJS fork as its scripting language. It is an actor based system, based on Douglas Crockford's Misty. It is a Meson compiled project with a number of dependencies.
+
+## File Structure
+- `source/`: Contains the C source code
+- `scripts/`: Contains script code that is loaded on executable start, and modules
+- `shaders/`: Contains shaders that ship with the engine (for shader based backends)
+- `benchmarks/`: Benchmark programs for testing speed
+- `tests/`: Unit tests
+- `examples/`: Contains full game examples
+
+## Coding Practices
+- Use K&R style C
+- Use as little whitespace as possible
+- Javascript style prefers objects and prototypical inheritence over ES6 classes, liberal use of closures, and var everywhere
+
+## Instructions
+- When generating code, adhere to the coding practices outlined above.
+- When adding new features, ensure they align with the project's goals.
+- When fixing bugs, review the code carefully before making changes.
+- When writing unit tests, cover all important scenarios.
+
+## Compiling, running, and testing
+- To compile the code, run "make", which generates a prosperon executable in build_dbg/, and copy it into the root folder
+- Run a test by giving it as its command: so ./prosperon tests/overling.js would run the test overling.js, ./prosperon tests/nota.js runs the nota benchmark
