If you just want to use the dapps, head to to create streams and to withdraw from streams. You'll need an Ethereum wallet and some ERC20 tokens to interact with the dapps.

To check out and compile the smart contracts, bootstrap the monorepo and head to each individual package as presented above. For example, these are the instructions for @sablier/protocol:

$ yarn run bootstrap
$ cd packages/protocol
$ truffle compile --all
$ truffle migrate --reset --network development
