 ## A note on process working directory
 
-The `dataDir` of these services tend to take *relative* paths, which are usually relative to the project root. As such, when you run these services using `nix run`, their data files are created relative to whichever directory you are in. If you want these data files to always reside relative to the project directory, instead of using `nix run` consider wrapping the process-compose packages in script, via either [mission-control](https://flakular.in/mission-control/) module or a [justfile](https://just.systems/). The example uses the latter.
