Yup, that’s a good point. I typically try to include the project and manifest files in the same folder as the tutorial, and I also like to explicitly add the Pkg.activate step to the tutorial itself so that a user following along will automatically get the right environment, as in https://github.com/rdeits/EdgeCameras.jl/blob/master/notebooks/demo.ipynb
I wasn’t aware that Pluto can embed the project files into the document–that’s super cool.
