# User Handbook - Third party tools and extras The Eden emulator by itself lacks some functionality - or otherwise requires external files (such as packaging) to operate correctly in a given OS. Addendum to that some repositories provide nightly or specialised builds of the emulator. While most of the links mentioned in this guide are relatively "safe"; we urge users to use their due diligence and appropriatedly verify the integrity of all files downloaded and ensure they're not compromised. - [Nightly Eden builds](https://github.com/pflyly/eden-nightly) - [NixOS Eden Flake](https://github.com/Grantimatter/eden-flake)
