How to run this collator

First, build Polkadot:

cargo build --release

Then start two validators that will run for the relay chain:

cargo run --release -- -d alice --chain rococo-local --validator --alice --port 50551
cargo run --release -- -d bob --chain rococo-local --validator --bob --port 50552

Next start the collator that will collate for the adder parachain:

cargo run --release -p test-parachain-adder-collator -- --tmp --chain rococo-local --port 50553

The last step is to register the parachain using polkadot-js. The parachain id is 100. The genesis state and the validation code are printed at startup by the collator.

To do this automatically, run scripts/adder-collator.sh.
