## Running a collator
1. Checkout polkadot at `bkchr-cumulus-branch`.
2. Build the polkadot chainspec:
`cargo run --release -- build-spec --chain=local --raw > polkadot_chainspec.json`
2. Run `Alice` and `Bob`:
Open the `polkadot_chainspec.json` and replace the `bootnodes` with: `"bootNodes": [],`
`cargo run --release -- --chain=${CUMULUS_REPO}/test/parachain/res/polkadot_chainspec.json --base-path=cumulus_relay_chain_node_0 --alice`
3. Run `Alice` and `Bob`:

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