-## Documentation
+## Contributing

+
+Please read our [contribution guidelines](./CONTRIBUTING.md) before getting started.
+
+### Install dependencies
+
+If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:
+
+```bash
+yarn config set workspaces-experimental true
+```
+
+Then install dependencies
+
+```bash
+yarn install
+```
+
+### Build
+
+If this is your **first** time building this package, you must first build **all** packages within the monorepo. This is because packages that depend on other packages located inside this monorepo are symlinked when run from **within** the monorepo. This allows you to make changes across multiple packages without first publishing dependent packages to NPM. To build all packages, run the following from the monorepo root directory:
+
+```bash
+yarn lerna:rebuild
+```
+
+Or continuously rebuild on change:
+
+```bash
+yarn dev
+```
+
+You can also build this specific package by running the following from within its directory:
+
+```bash
+yarn build
+```
+
+or continuously rebuild on change:
+
+```bash
+yarn build:watch
+```
+
+### Clean
+
+```bash
+yarn clean
+```
