+## Building and Running as Parachain locally
+
+Rust toolchain: nightly-2021-04-23
+Note: checkout this project and polkadot project (see below) in the sibling folders (both under the same folder)
+
+### Parachain Code and Other Configurations
+
+Some changes need to be made in the parachain code depending on the relay chain it connects to
+
+1. Chain Spec (incl. chain_spec.rs)
+```
+Extensions {
+  relay_chain: "rococo".into(),
+  para_id: PARA_ID,
+}
+```
+
+2. All collators need to have at least existential balance
+
+
+
+
+### Build relay
+
+```
+git clone https://github.com/paritytech/polkadot.git
+cd polkadot
+git checkout aa386760
+cargo build --release
+```
+
+### Build parachain
+
+Run in the root of this project:
+```
+cargo --build
+```
+
+### Run 4-node Relay
+
+1. Download `rococo-custom-4.json` chain spec here: https://substrate.dev/cumulus-workshop/shared/chainspecs/rococo-custom-4.json
+2. Use these instructions to launch 4 nodes: https://substrate.dev/cumulus-workshop/#/en/2-relay-chain/1-launch
+
+Example (Run in polkadot folder. Replace `12D3KooWNLAmKcyee3oqSgTMthaQVXaAcXeo8RrGCzMfMVA3B5on` with output from Alice node):
+```
+./target/release/polkadot --alice --validator --base-path ./cumulus_relay0 --chain rococo-custom-4.json --port 50555 --ws-port 9944
+./target/release/polkadot --bob --validator --base-path ./cumulus_relay1 --chain rococo-custom-4.json --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/12D3KooWNLAmKcyee3oqSgTMthaQVXaAcXeo8RrGCzMfMVA3B5on --port 50556 --ws-port 9945

+
+```
+
+3. Export genesis state and runtime wasm from NFT parachain:
+
+Run from this project root:
+```
+./target/release/nft export-genesis-state --parachain-id 2000 > ./resources/para-2000-genesis
+./target/release/nft export-genesis-wasm > ./resources/para-2000-wasm
+```
+
+4. Run two parachain nodes:
+
+Replace `12D3KooWN1ah2bFQSysEFnwZqcmcVpDDR8UedXyo6xfzV1zDNMNg` with Alice or Bob relay ID
+
+Run from this project root:
+```
+./target/release/nft --alice --collator --force-authoring --base-path ./tmp/parachain-alice --parachain-id 2000 --port 40333 --ws-port 9844  -- --execution wasm --chain ../polkadot/rococo-custom-4.json --port 30343 --ws-port 9977
+./target/release/nft --bob --collator --force-authoring --parachain-id 2000 --base-path ./tmp/parachain/bob --port 40334 --ws-port 9845 -- --execution wasm --chain ../polkadot/rococo-custom-4.json --port 30344 --ws-port 9978 --bootnodes /ip4/127.0.0.1/tcp/50556/p2p/12D3KooWN1ah2bFQSysEFnwZqcmcVpDDR8UedXyo6xfzV1zDNMNg
+```
+
+4. Reserve parachain ID as described here: https://substrate.dev/cumulus-workshop/#/en/2-relay-chain/2-reserve
+
+5. Register parachain in relay as described here: https://substrate.dev/cumulus-workshop/#/en/3-parachains/2-register
