+
+open-source version of a liquidation bot running against Solend
+
+## Overview
+
+The Solend liquidator bot identifies underwater obligations to liquidate. Solend awards liquidators a 5% bonus on each liquidation. See [Solend params](https://docs.solend.fi/protocol/parameters) for the most up-to-date parameters on each asset. This repo is intended as a starting point for the Solend community to build liquidator bots.
+
+## Usage
+
+1. Install [docker-compose](https://docs.docker.com/compose/install/)
+2. Verify you have docker-compose installed by running the following
+
+```
+docker-compose --version
+```
+
+3. Update [file system wallet](https://docs.solana.com/wallet-guide/file-system-wallet) path in docker-compose.yaml.
+
+```
+version: "3.1"
+
+services:
+  # The application image
+  solend-liquidator:
+    restart: unless-stopped
+    build:
+      context: .
+      dockerfile: Dockerfile
+    environment:
+      - NETWORK=mainnet # solana network e.g mainnet, devnet
+      - THROTTLE=600 # Throttle not avoid rate limiting
+    secrets:
+      - keypair # secret to encrypte wallet details in container
+
+secrets:
+  keypair:
+    file: <PATH TO KEYPAIR WALLET THAT WILL BE LIQUIDATING UNDERWATER OBLIGATIONS>
+```
+
+4. Build and run service
+
+```
+docker-compose up --build
+```
+
+## Support
+
+PRs to improve this repo are welcomed! If you need help setting up your liquidator bot, feel free to post your questions in liquidator channel within [Solend's discord server](https://discord.gg/exscEFpB7s).
