# PLP Liquidation Instructions

The following document describes how to undertake liquidations. It also includes links to our template liquidation bot as a starting point to help liquidators build their more sophisticated, custom liquidation engines.

The liquidation query (described in the embedded document - in relation to the liquidation query NPM package <https://www.npmjs.com/package/@fringefinance/primary-scripts>) requires you to define the setup in `.env` files - which declare the relevant Fringe V2 contract addresses and subgraph query endpoints. The setups required for the `.env` file for each chain are listed below \

(you'll also find related instructions in the github repo README.md file for the Fringe V2 liquidation bot ==>  : <https://github.com/fringe-finance/liquidation-bot/tree/master>)
