Demonstrate creating YAML file with explicit reference to schema.

[IanMayo]

Modify the README to include steps (with images) for creating YAML file (in the root of a cloned version of this repo) with the first line specifying which schema the file must match.

Any screenshots should go into an images sub-folder, and have useful titles that match the contents.

@Talented0217 - I don't think this issue has been demonstrated. The YAML file should specify which schema it is using.

I've done it

By declaring the schema to use, we don't need to configure settings.json

Hmm, missile-strike.YAML should specify which schema it adheres to.

Elsewhere we have demonstrated how to configure VS-Code to know which schema to do, but the requirement in this issue is for the YAML file to declare which schema to use.

Anyway, I've added for both.
Head of yaml file, I've defined the code which schema was used. And also in settings.json for VS-code added the pairs of schema and yaml.
