+# Granian Benchmark Test
+
+This is the Granian portion of a [benchmarking tests suite](../../) comparing a variety of web development platforms.
+
+The information below is specific to Granian. For further guidance, review the [documentation](https://github.com/TechEmpower/FrameworkBenchmarks/wiki).
+
+Also note that there is additional information provided in the [Python README](../).
+
+## Description
+
+[Granian](https://github.com/emmett-framework/granian) is an asyncio server for Python applications.
+
+## Test Paths & Source
+
+Granian includes two different implementations:
+
+- ASGI implementation in the [app\_asgi.py](app_asgi.py)
+- RSGI implementation in the [app\_rsgi.py](app_rsgi.py)
+
+Both implementations includes the following tests:
+
+* JSON Serialization: "/json"
+* Plaintext: "/plaintext"
+
+*Replace # with an actual number.*
+
+## Resources
+
+* [Github repository](https://github.com/emmett-framework/granian)
