+# Emmett Benchmark Test
+
+[Emmett](https://github.com/emmett-framework/emmett) is a fullstack Python asyncIO web framework.
+
+This test uses the included ORM and templating engine, and uvicorn for the application server on CPtyhon.
+
+## Test Paths & Source
+
+* [JSON Serialization](app.py): "/json"
+* [Single Database Query](app.py): "/db"
+* [Multiple Database Queries](app.py): "queries?queries=#"
+* [Fortunes](app.py): "/fortunes"
+* [Database Updates](app.py): "updates?queries=#"
+* [Plaintext](app.py): "/plaintext"
+
+*Replace # with an actual number.*
+
+### Resources
