WIP - Be patient, in the meantime:
This repo uses Dev Container to provide a development environment with all the tools you need to start developing. Make sure to VS Code Dev Containers extension installed and also have Docker installed and running on your machine.
Create a .env file in the root of the project with the following content by copying the .env.sample file. The sample file is already configured to work with the development environment, so unless you want to change something (for example connect to a differnt server or database, you can leave it as is).
Open the terminal and run
dotnet tool install Microsoft.DataApibuilder -gto install Data API builder, than
dab start -c config/dab-config-auth.json --no-https-redirect
to run Data API builder.
