+# Substrate Cumulus Parachain Template
+
+A new [Cumulus](https://github.com/paritytech/cumulus/)-based Substrate node, ready for hacking ☁️..
+
+This project is a fork of the [Substrate Node Template](https://github.com/substrate-developer-hub/substrate-node-template)
+modified to include dependencies required for registering this node as a **parathread** or
+**parachain** to the Rococo **relay chain**.
+Rococo is [Polkadot's parachain testnet](https://polkadot.network/blog/introducing-rococo-polkadots-parachain-testnet/) 👑.
+
+👉 Learn more about parachains [here](https://wiki.polkadot.network/docs/learn-parachains), and
+parathreads [here](https://wiki.polkadot.network/docs/learn-parathreads).
+
+To learn about how to actually use the template to hack together your own parachain check out the
+`README` from the [`substrate-parachain-template` repository](https://github.com/substrate-developer-hub/substrate-parachain-template/).
