+# OpenAPI 3.0 Schema Generator
+
+This directory contains a support tool that reads (scrapes) the
+Markdown text specification for OpenAPI 3.0 and builds a 
+corresponding JSON schema.
+
+It also contains "3.0.md", a local copy of the OpenAPI specification
+with modifications that fix minor inconsistencies and make it easier
+to read. We hope to have these changes merged into the official 
+document.
+
+## Disclaimer
+
+This does not generate the official OpenAPI 3.0 JSON Schema, which 
+at the time of this commit, does not exist.
