 want to send all of those files to production when we publish our
 application. In order to overcome this, we have used gulp to move
 necessary files from **\*.Web.Mvc/node\_modules** to
-**\*.Web.Mvc/wwwroot/lib**. There are two related files in \*.Web.Mvc
-project, **bundle.config.js** and **gulpfile.js**. **bundle.config.js**

-respectively in below screenshots mapping and bundling/minification
-configurations from bundle.config.js.
+**\*.Web.Mvc/wwwroot/lib**. Mapping from node_modules to wwwroot/lib folder is defined in **package-mapping-config.js** file. So, when you add a new package to your solution, you also need to add a mapping to this file defining the files you want to move from node_modules to wwwroot/lib folder for newly added package.

-In order to create css and javascript bundles "gulp" command must be runned in the root directory of ***.Web.Mvc** solution using a command prompt. This can be done using Visual Studio's Task Runner Explorer. Default gulp task doesn't end and it watches for changes in the css & javascript files used in **bundle.config.js** file. If ""--prod" argument is not passed to gulp command, css and javascript bundles will not be minified in order to provide developers a better debug experience. Running "**gulp --prod**" command will minify output css and javascript files. For Continuous Integration pipelines "gulp build:prod" command can be used, because this task ends with an exit code so, CI environments can understand.
+In order to create css and javascript bundles https://www.nuget.org/packages/BundlerMinifier.Core/ package is used. Bundling definitions are stored in **bundleconfig.json** file. If you don't want to modify this file manually, you can use https://marketplace.visualstudio.com/items?itemName=MadsKristensen.BundlerMinifier Visual Studio extension to create bundling definitions for you.
