+This is an example package that can be used to test Yarn.
+
+It has the common default fields in its `package.json`, along with production and development dependencies as well that
+are specific to the package we have created.
+
+## The `package.json`
+
+### Default Package Fields
+
+`yarn init` produces a default `package.json` similar to:
+
+```
+{
+  "name": "example-yarn-package",
+  "version": "1.0.0",
+  "description": "An example package to demonstrate Yarn",
+  "main": "index.js",
+  "repository": {
+    "url": "github.com/yarnpkg/example-yarn-package",
+    "type": "git"
+  },
+  "author": "Yarn Contributors",
+  "license": "BSD-2-Clause",
+}
+```
+
+### Custom Package Fields
+
+You can add custom fields to your `package.json` as well. In our case, we have added 4 custom fields.
+
+The `scripts` field are for any special scripts that you want to use when running `yarn`. For example, here we add a
+script called `test` that calls the Jest test runner because we added Jest tests to our Yarn package.
+
+```
+"scripts": {
+  "test": "jest"
+},
+```
+
+The `dependencies` field lists the other packages that this package is dependent upon. Our example package is dependent
+on [Lodash](https://lodash.com/) since we use its `multiply` function.
+
+```
+"dependencies": {
+  "lodash": "^4.16.2"
+},
+```
+
+The `devDependencies` field lists the other packages that this package is dependent upon *during development*. Our
+example package is dependent on [Jest](https://facebook.github.io/jest/) since we created some Jest-enabled tests for
+our package.
+
+```
+"devDependencies": {
+  "jest-cli": "15.1.1"
+},
+```
+
+The `jest` field is a custom field specific to the Jest package we included as a dev dependency. In this case, we are
+testing
+in a node environment at the command-line.
+
+```
+"jest": {
+  "testEnvironment": "node"
+}
+```
+
+> It is important to note that Lodash and Jest are not required for Yarn. They are just examples of what can be used
+> when you are creating the code for your Yarn package.
+
+## Development
+
+```
+$ yarn install
+$ yarn run test
+```
+
+## Production
+
+```
+$ yarn install --production
+```
