To access Pkg mode in a Julia REPL session, press ] at the start of a new prompt line. Press backspace on an empty line to exit.

Here are some Pkg mode commands that might be useful for me. Note that the description isn’t a complete one, just a note to myself

Command Purpose
help Print the command descriptions.
activate Activate an environment.
instantiate Download packages in Manifest.toml (creates one if not existing).
resolve Make the Manifest.toml consistent if dependencies modified.
test Run tests.
update Update packages.
precompile Precompile dependencies. Called automatically after any Pkg action that changes the Manifest.toml.
build Run build script (usually not needed).

Should the Manifest.toml be committed to git?

Case Commit Manifest.toml?
End-stage product? Yes
Reusable library? No
