+# OpenAPI specification
+
+This directory includes the OpenAPI spec for the ABS server.
+The spec is made up of a number of individual `yaml` files located here and in the subfolders, with `root.yaml` being the file that references all of the others.
+The files are organized to have the same hierarchy as the server source files.
+The full spec is bundled into one file in `openapi.json`.
+
+The spec is linted and bundled by the [`vacuum` tool](https://quobix.com/vacuum/).
+The spec can also be tested with a real server using the [`wiretap` tool](https://pb33f.io/wiretap/).
+Both of these tools are created by [pb33f](https://pb33f.io/).
+
+### Bundling the spec
+The command to bundle the spec into a `yaml` file is `vacuum bundle root.yaml openapi.yaml`.
+
+The current version of `vacuum` cannot convert input `yaml` files to `json` files.
+To convert the spec to `json`, you can use the `yq` tool or another tool.
+
+The command to convert the spec using `yq` is `yq -p yaml -o json openapi.yaml > openapi.json`.
+
+### Viewing report
+To generate an HTML report, you can use `vacuum html-report [file]` to generate `report.html` and view the report in your browser.
+
+### Putting it all together
+The full command that I run to bundle the spec and generate the report is:
+
+```
+vacuum bundle root.yaml openapi.yaml && \
+yq -p yaml -o json openapi.yaml > openapi.json && \
+vacuum html-report openapi.json
+```

+              epic Sword of Truth In the aftermath of the brutal murder of his father,
+              a mysterious woman, Kahlan Amnell, appears in Richard Cypher's forest
+              sanctuary seeking help...and more. His world, his very beliefs, are
+              shattered when ancient debts come due with thundering violence. In a
+              dark age it takes courage to live, and more than mere courage to
+              challenge those who hold dominion, Richard and Kahlan must take up that
+              challenge or become the next victims. Beyond awaits a bewitching land
+              where even the best of their hearts could betray them. Yet, Richard
+              fears nothing so much as what secrets his sword might reveal about his
+              own soul. Falling in love would destroy them - for reasons Richard can't
+              imagine and Kahlan dare not say. In their darkest hour, hunted
+              relentlessly, tormented by treachery and loss, Kahlan calls upon Richard
+              to reach beyond his sword - to invoke within himself something more
+              noble. Neither knows that the rules of battle have just changed...or
+              that their time has run out. Wizard's First Rule is the beginning. One
+              book. One Rule. Witness the birth of a legend.
