+The release-tonpm can be used to publish images to npm. 
+The below pipeline configuration demonstrates simple usage:
+
+deploy_to_npm:
+  title: Publishing To Npm
+  image: codefresh/release-tonpm:latest
+  commands:
+    - NPM_TOKEN=${{NPM_TOKEN}} npm run ci-publish
+  when:
+    branch:
+      only: [ master ]
+        
+        
+Login into your project's NPM registry
+
+npm login --registry <registry url>
+npm login --registry http://registry.npmjs.org
+
+Copy the token
+The login step added a line to your ~/.npmrc file looking something like this
+
+//registry.npmjs.org/:_authToken=00000000-0000-0000-0000-000000000000
+
+Grab the auth token value 00000000-0000-0000-0000-000000000000 (older NPM proxies or registries like sinopia might have an older different token string format)
+
+Set the token as CI environment variable
+Go to your CI project settings and add a new variable NPM_TOKEN with the value you have just copied
