I've cloned a Julia project and need to set it up. What is the command to install all its dependencies and make them ready for use? Also, how can I launch Julia from my command line and automatically use this specific project's environment?
Navigate to the 'Working with Environment' section of the Pkg.jl documentation. Go to the 'Using someone else's project' subsection. Identify the Julia command used to install and precompile dependencies for an existing project. Identify the command-line flag used to specify a project when starting Julia. Synthesize the identified command and flag into a concise answer.
State that `Pkg.instantiate()` is the command to set up and install dependencies for an existing project. Mention the `--project` flag for specifying a project on Julia startup, including an example like `julia --project=.`.
