Configuration for developing a substrate project in a docker container using VS Code's remote containers feature.
Check out the main vs code remote development page for a list of reasons to use devcontainers. In short: it gives you a reproducible, disposable development environment.
Clone the repo and then either
(A) create a link to the .devcontainer from your project root (cd my-project-root && ln path-to-vscode-substrate-devcontainer/.devcontainer);
or (B) copy the .devcontainer folder into your project root.
Now, in VS Code, open the command pallet (cmd-shift-P) and look for Remote Containers - Open Folder in Container... and
navigate to your project root folder. The first time it will take a while to download and build the dependencies.
