4. Run the collator:

`cargo run --release -p cumulus-test-parachain-collator -- -d cumulus_collator_path --chain polkadot_chainspec.json --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/PEER_ID`
`cargo run --release -p cumulus-test-parachain-collator -- --base-path cumulus_collator_path --chain polkadot_chainspec.json --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/PEER_ID`

`PEER_ID` needs to be replaced with the peer id of the polkadot validator that uses `Alice`
as authority.

5. Open `https://polkadot.js.org/apps/#/sudo` and register the parachain.
5. Open `https://polkadot.js.org/apps/#/sudo` and register the parachain by calling `Registrar > RegisterPara`

`id`: `100`

`initial_head_data`: Use the file you generated in 3. (name: genesis-state)
`ParaInfo`: `Always`

`code`: `CUMULUS_REPO/target/release/wbuild/cumulus-test-parachain-runtime/cumulus_test_parachain_runtime.compact.wasm`

`initial_head_data`: Use the file you generated in 4. (name: genesis-state)

Now your parachain should be registered and the collator should start building blocks and sending
them to the relay chain.
