Setup

At webpack we use yarn to execute commands.

If you already have yarn installed, do: yarn setup. This will complete all required steps.

If not, do: npm run setup, the setup will also install yarn for you.

That's all.

Setup manually

Setup your local webpack repository

git clone https://github.com/webpack/webpack.git
cd webpack
npm install -g yarn
yarn
yarn link
yarn link webpack
