 Increased performance can be achieved for transpilers written in Luau that may not be able to have a static environment created to access functions from or cant directly transpile 1:1. Similarly
 interpreters written in Luau can benefit from being able to access functions without deoptimization, making other optimizations still active.

 ## Design
 
-...
+A safe way to access the environment is with a read-only table with `__index` and `__iter` metamethods.
+
+a) `_ENV` table 
+
+A read-only global table with metamethods that point to `LUA_ENVIRONINDEX`.
+
+b) `getenv` or `getrenv` function 
+
+Works identically to `getfenv` but only provides read-only access to the function's environment.
 
 ## Drawbacks
 
-...
+Type-checking can be difficult.
 
-## Alternatives
-
-...
+Roblox's marketplace currently hides assets that use `getfenv` so it would need to be updated to hide assets with `_ENV`/`getenv`/`getrenv`.
