Kleros Court is the implementation of an arbitrator as per the we developed. Most integrations consist in building or customizing an Arbitrable app so it can request arbitration to Kleros Court. Once you integrate with the Arbitration standard, you (or your users) will be able to choose any arbitrator that follows the standard to solve disputes, including Kleros.
You can build an arbitrable smart contract or ensure your existing smart contracts are compliant with the Arbitrable interface:

Some extra data to set up the arbitration (that will specify the sub-court to be used and the number of vote required)
List of subcourt IDs below,
We recommend starting with 3 votes.
Script to generate the arbitrator extra data
generateArbitratorExtraData = (subcourtID, noOfVotes) => 0x${parseInt(subcourtID, 10).toString(16).padStart(64, "0") + parseInt(noOfVotes, 10).toString(16).padStart(64, "0")};
(If appeals are allowed) Stake multipliers representing multipliers of the appeal cost that a party must pay for a new round (in basis points)
