+# Heroku Cloud Native npm Install Buildpack
+
+[![CI][CI BADGE]][CI LINK] [![Registry][Registry BADGE]][Registry LINK]
+
+Heroku's official Cloud Native Buildpack for executing `npm install`.
+
+## How it works
+
+The buildpack will pass detection if:
+
+- A `package-lock.json` file is found at the root of the application source.
+
+### Step 1: Configure npm cache
+
+Node modules downloaded during the [install step](#step-2-install-node-modules) will be cached. Subsequent builds will use 
+this cache speed up installs.
+
+### Step 2: Install Node modules
+
+Node modules are installed by executing `npm ci --production=false`.
+
+### Step 3: Execute build scripts
+
+The following scripts will be executed with `npm run <script>` in the order listed:
+
+- `heroku-prebuild`
+- `heroku-build` or `build` (if both are present, only `heroku-build` will execute)
+- `heroku-postbuild`
+
+If any of the above scripts are not defined in `package.json` they will be skipped. 
+
+### Step 4: Configure processes
+
+If there is a `start` script defined in `package.json` a default `web` process will be
+added that executes `npm start`.

+| `node`         | To execute `npm` a [Node.js][Node.js] runtime is required. It can be provided by the [`heroku/nodejs-engine`][heroku/nodejs-engine] buildpack.                                                                             |
+| `npm`          | To install node modules, the [npm][npm] package manager is required. It can be provided by either the [`heroku/nodejs-engine`][heroku/nodejs-engine] or [`heroku/nodejs-npm-engine`][heroku/nodejs-npm-engine] buildpacks. |
+| `node_modules` | This is not a strict requirement of the buildpack. Requiring `node_modules` ensures that this buildpack can be used even when no other buildpack requires `node_modules`.                                                  |

+|----------------|-----------------------------------------------------------------------------------|
+| `node_modules` | Allows other buildpacks to depend on the Node modules provided by this buildpack. |
