Workspaces are a way of managing multiple packages in one repo.
In this repo workspaces are found in the "workspaces" folder and are also grouped in sub-directories. This means that you cannot add a package directory directly to the "workspaces" directory. You need to place it in another direcotry. This approach aids organisation. Example layout:
workspaces/
frontend/
web-app/
package.json
marketing-site/
package.json
backend/
graphql-service/
package.json
file-service/
package.json
shared/
common/
package.json
