+> Yet another GraphQL module for Deno
+
+## Why?
+
+I forked [gql](https://github.com/deno-libs/gql/issues/14#issuecomment-1472911645) while investigating adding plugin support. Then I realized it'd be great to include the modules I typically use when creating GraphQL APIs. Copy/pasting folders into new projects is so 2012.
+
+## Features
+
+- import `*.graphql` files to form your schema
+- GraphiQL code is cleaned up and the SVGs actually make sense (and are readable)
+- passes `deno check mod.ts` without issue
+- more stuff
+
+## TODO
+
+- add proper README
+- add tests
+- add example(s)
+- replace React with Svelte/SvelteKit for GraphiQL
+- take over the world
+ - real world, metaverse, or yggdrasil (ipv6 mesh network), whichever comes first
+- adhere to `no-explicit-any` (make `deno lint` proud)
