+### lockfile-lint
+
+The [`lockfile-lint`](https://github.com/lirantal/lockfile-lint) allows us to enforce additional
+security policies regarding NPM package sources, such as allowed package registries and code
+sources and package source HTTP protocols.
+
+To configure the tool, add a file named `.lockfile-lint.config.js` to your project root,
+with the following contents:
+
+```js
+'use strict';
+
+const sharedConfig = require('@silvermine/standardization/.lockfile-lint.shared.js');
+
+module.exports = {
+
+   ...sharedConfig,
+
+   // Add any overrides here.
+   // See the lockfile-lint docs for more information.
+
+};
+
+```
+
+Then add the following NPM script to your `package.json` file. Call the script as part
+of the tooling chain in the `standards` NPM script:
+
+```json
+{
+   "scripts": {
+      "lockfile-lint": "lockfile-lint",
+      "standards": "npm run lockfile-lint && npm run markdownlint"
+   }
+}
