-# Polkadot Benchmarking Test
-
-This is the [`polkadot`](https://github.com/lukeed/polkadot) portion of a [benchmarking test suite](../) comparing a variety of web development platforms.
-
-Information about Polkadot can be found at https://github.com/lukeed/polkadot
-
-## Database Drivers
-
-There are individual handlers for each DB approach. The logic for each of them are found here:
-
-* [MySQL](drivers/mysql.js)
-* [MongoDB](drivers/mongodb.js)
-* [PostgreSQL](drivers/postgres.js)
-
-There are **no database endpoints** or drivers attached by default.<br>
-To initialize the application with one of these, run any _one_ of the following commands:
-
-```sh
-$ DATABASE=mysql node app.js
-$ DATABASE=mongodb node app.js
-$ DATABASE=postgres node app.js
-```
-
-## Test Endpoints
-
-> Visit the test requirements [here](https://github.com/TechEmpower/FrameworkBenchmarks/wiki/Project-Information-Framework-Tests-Overview)
-
-```sh
-$ curl localhost:8080/json
-$ curl localhost:8080/plaintext
-
-# The following are only available w/ DATABASE
-# ---
-
-$ curl localhost:8080/db
-$ curl localhost:8080/fortunes
