# Juror Tutorial (V1)

This tutorial explains how to become a juror on **Kleros Court V1** at [court.kleros.io](https://court.kleros.io/) (Ethereum Mainnet and Gnosis Chain). For the next-generation court on Arbitrum, see the [V2 Juror Tutorial](/tutorials/juror-tutorial-v2). No signup or personal information is required: you only need the right tools and skills.

## Tooling

You need:

* A Web3 wallet such as MetaMask
* PNK tokens
* ETH for gas fees

The fastest way to obtain PNK is directly from the [Buy PNK page of the Court](https://court.kleros.io/tokens) or from one of the exchanges listed there.

<Note>
  Once you stake in a court, you are automatically staked in all courts above it up to the General Court, for appeal purposes.
</Note>

<Warning>
  Review the court policies carefully before voting. Jurors who vote incoherently with the final ruling lose a portion of their staked PNK.
</Warning>
