In a lot of projects, this is usually done via README. It tells you what running dependencies to install and how to run certain commands.
This can get harder to maintain as things change, the project grows, and complexity increases.
I see two parts to automate here: actually setting up the environment, and running the application or orchestrating multiple apps.
How do you address this?
For toolchains like rust, go, c#, typescript/nodejs how would “things get ugly very fast” when making the toolchain an env dependency?
