-## Hackusama Update
-
-During the Kusama Hackaphon the following changes were made:
-
--   Enabled Smart Contracts Pallet
--   Enabled integration between Smart Contracts and Unique Pallet (required special edition of RC4 Substrate version)
--   Fixed misc. bugs in Unique Pallet
--   Deployed Unique TestNet. Public node available at wss://unique.usetech.com, custom UI types - see below in this README.
--   New Features:
-    -   Re-Fungible Token Mode
-    -   Off-Chain Schema to store token image URLs
-    -   Alternative economic model
-    -   Allow Lists and Public Mint Permission
--   Use example: [SubstraPunks Game](https://github.com/usetech-llc/substrapunks), fully hosted on IPFS and Unique Testnet
-    Blockchain.

-You can start a development chain with:
-
-```bash
-cargo run -- --dev

-
-Detailed logs may be shown by running the node with the following environment variables set:
-`RUST_LOG=debug RUST_BACKTRACE=1 cargo run -- --dev`.
+## Building as Parachain locally
 
-If you want to see the multi-node consensus algorithm in action locally, then you can create a local testnet with two
-validator nodes for Alice and Bob, who are the initial authorities of the genesis chain that have been endowed with
-testnet units. Give each node a name and expose them so they are listed on the Polkadot
-[telemetry site](https://telemetry.polkadot.io/#/Local%20Testnet). You'll need two terminal windows open.
+Note: checkout this project and all related projects (see below) in the sibling folders (both under the same folder)
 
-We'll start Alice's substrate node first on default TCP port 30333 with her chain database stored locally at
-`/tmp/alice`. The bootnode ID of her node is `QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN`, which is generated from
-the `--node-key` value that we specify below:

-  --telemetry-url ws://telemetry.polkadot.io:1024 \
-  --validator
 ```
-
-In the second terminal, we'll start Bob's substrate node on a different TCP port of 30334, and with his chain database
-stored locally at `/tmp/bob`. We'll specify a value for the `--bootnodes` option that will connect his node to Alice's
