-which we plan to use for both Rococo and Kusama.

-## Developing Smart Contracts for Canvas
-
-![Canvas Overview](./docs/canvas-overview.svg)
-
-This node contains Substrate's smart contracts module ‒ the
-[`contracts`](https://github.com/paritytech/substrate/tree/master/frame/contracts) pallet.
-This `contracts` pallet takes smart contracts as WebAssembly blobs and defines an API
-for everything a smart contract needs (storage access, …).
-As long as a programming language compiles to WebAssembly and there exists an implementation
-of this API in it, you can write a smart contract for this pallet ‒ and thus for Canvas ‒ in
-that language.
-
-This is a list of languages you can currently choose from:
-
-* [Parity's ink!](https://github.com/paritytech/ink) for Rust
-* [ask!](https://github.com/patractlabs/ask) for Assembly Script
-* The [Solang](https://github.com/hyperledger-labs/solang) compiler for Solidity
-
-There are also different user interfaces and command-line tools you can use to deploy
-or interact with contracts:
-
-* [polkadot-js](https://polkadot.js.org/apps/)
-* [Canvas UI](https://paritytech.github.io/canvas-ui/) (outdated)
-
-If you are looking for a quickstart, we can recommend
-[ink!'s Guided Tutorial for Beginners](https://docs.substrate.io/tutorials/v3/ink-workshop/pt1/).
-
-### Build & Launch a Node
-
-To run a Canvas node that connects to Rococo (Kusama and Polkadot parachains are not deployed, yet)
-you will need to compile the `polkadot-parachain` binary:
-
-```bash
-cargo build --release --locked -p polkadot-parachain
-```
-
-Once the executable is built, launch the parachain node via:
-
-```bash
-./target/release/polkadot-parachain --chain rocanvas
-```
-
-Refer to the [setup instructions below](#local-setup) to run a local network for development.
-
-### Rococo Deployment
-
-We have a live deployment of the Canvas parachain on [Rococo](https://wiki.polkadot.network/docs/build-pdk#rococo-testnet) ‒
-a testnet for Polkadot and Kusama parachains.
-You can interact with the network through Polkadot JS Apps,
-[click here for a direct link to Canvas](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frococo-canvas-rpc.polkadot.io#/explorer).
-
-The Canvas parachain uses the Rococo relay chain's native token (ROC) instead of having its own token.
-Due to this you'll need ROC in order to deploy contracts on Canvas.
-
-As a first step, you should create an account. See [here](https://wiki.polkadot.network/docs/learn-account-generation)
-for a detailed guide.
-
-As a second step, you have to get ROC testnet tokens through the [Rococo Faucet](https://wiki.polkadot.network/docs/learn-DOT#getting-rococo-tokens).
-This is a chat room in which you need to write:
-
-```bash
-!drip YOUR_SS_58_ADDRESS:1002
-```
-
-The number `1002` is the parachain id of Canvas on Rococo, by supplying it the faucet will teleport ROC
-tokens directly to your account on the parachain.
-
-If everything worked out, the teleported ROC tokens will show up under
-[the "Accounts" tab for Canvas](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frococo-canvas-rpc.polkadot.io#/accounts).
-
-Once you have ROC on Canvas you can deploy a contract as you would normally.
-If you're unsure about this, our [guided tutorial](https://docs.substrate.io/tutorials/v3/ink-workshop/pt1/)
-will clarify that for you in no time.
+See [the `contracts-rococo` readme](polkadot-parachains/contracts-rococo/README.md) for details.
