Original prompt

create a how-to guide focusing on the basics of creating a configuration file. discuss general config behavior (like cascading overrides made in the level of specificity) and the most commonly used config options. add a section an telemetry.

create a focused how to about setting up an OpenAPI integration in the config.

update the contexts page to discuss how to choose and specify a context.

link to the different input typed as appropriate, including creating a custom file type.

identify other config-related how to subjects and create context for them.
