##Usage

• add a package.json file in your customization package folder root.

For example, if you are developing a package for the Auto1 view

• Add the file under primo-explore-devenv/primo-explore/custom/Auto1

• The content of the file should be:

{
  "name": "<your view code>",
  "version": "<your version>",
  "description": "",
  "author": "",
  "devDependencies": {
    "primo-explore-altmetrics-widget": "0.0.1"
  }
}

• go to your command line (in windows: type cmd in the start > run box)

• navigate to the location of the package.json file

     cd primo-explore-devenv/primo-explore/custom/Auto1

• type npm install

• you will se a new folder was added in the same location named node_modules

• Now you can see the widget in your full view once you find a record with a doi field
