-`glacier2obj` provides functionality to search for mesh (PRIM) files with a Glacier scene from the Hitman games. Eventually it will also convert them into an OBJ file.
+`glacier2obj` provides functionality to search for mesh collision (ALOC) files with a Glacier scene from the Hitman games.
 
 ## Features
 
-- Read from Glacier scene files and search for PRIM files using [`rpkg-rs`](https://github.com/dafitius/rpkg-rs)
-
-## Future Plans
-
-- Convert all PRIMs to a single OBJ file for use with [`recastnavigation-glacier`](https://github.com/dbierek/recastnavigation-glacier).
+- Communicate with the Editor SDK mod for Hitman 3 for a loaded mission to get collision (ALOC) hashes and transforms, and Pathfinder box transforms and save them to files
+- Extract the ALOC files using [`rpkg-rs`](https://github.com/dafitius/rpkg-rs)

 Bug reports, PRs and feature requests are welcome.
