1. Installing Brownie: Brownie is a python framework for smart contracts development,testing and deployments. It's quit like HardHat but it uses python for writing test and deployements scripts instead of javascript. Here is a simple way to install brownie.

    pip install --user pipx
    pipx ensurepath
    # restart your terminal
    pipx install eth-brownie
   

   Or if you can't get pipx to work, via pip (it's recommended to use pipx)

   pip install eth-brownie
   

   Install ganache-cli:

    npm install -g ganache-cli

2. Clone the repo:

   git clone https://github.com/kaymen99/aave-flashloan-arbitrage.git
   cd aave-flashloan-arbitrage

3. Set your environment variables:

   To be able to deploy to real testnets you need to add your PRIVATE_KEY (You can find your PRIVATE_KEY from your ethereum wallet like metamask) and the infura project Id (just create an infura account it's free) to the .env file:

   PRIVATE_KEY=<PRIVATE_KEY>
   WEB3_INFURA_PROJECT_ID=<< YOUR INFURA PROJECT ID >>
   

To start an arbitrage on the mainnet fork (for testing purposes only, you can also use the kovan testnet) you just need to run the command :

brownie run scripts/flashloan_arbitrage.py --network=mainnet-fork
