+Monorepo with packages for setting up ESLint, Typescript, Prettier and Jest.
+
+## Presentation
+
+The goal of the project is too have a set of configuration files that can be easily imported into a new project, which would reduce the burden of starting new projects.
+
+This repo uses [lerna](https://lerna.js.org/) to maintain, version and publish various packages for configuring ESLint, Typescript, Prettier and Jest.
+
+There is also an example app under `packages/example-app` whose goal is to demonstrate how to import and use the configuration packages.
+
+## Commands
+
+- `yarn lerna run start`: run the 'start' script in all packages (currently only present in `example-app`),
+- `yarn lerna run lint`: run the 'lint' script in all packages (currently only present in `example-app`).
