+
+## Installation
+
+### For [Node.js](https://nodejs.org/)
+
+#### npm
+
+To publish the library as a [npm](https://www.npmjs.com/), please follow the procedure in ["Publishing npm packages"](https://docs.npmjs.com/getting-started/publishing-npm-packages).
+
+Then install it via:
+
+```shell
+npm install {{{projectName}}} --save
+```
+
+Finally, you need to build the module:
+
+```shell
+npm run build
+```
+
+##### Local development
+
+To use the library locally without publishing to a remote npm registry, first install the dependencies by changing into the directory containing `package.json` (and this README). Let's call this `JAVASCRIPT_CLIENT_DIR`. Then run:
+
+```shell
+npm install
+```
+
+Next, [link](https://docs.npmjs.com/cli/link) it globally in npm with the following, also from `JAVASCRIPT_CLIENT_DIR`:
+
+```shell
+npm link
+```
+
+To use the link you just defined in your project, switch to the directory you want to use your {{{projectName}}} from, and run:
+
+```shell
+npm link /path/to/<JAVASCRIPT_CLIENT_DIR>
+```
+
+Finally, you need to build the module:
+
+```shell
+npm run build
+```
+
+#### git
+
+If the library is hosted at a git repository, e.g.https://github.com/{{#gitUserId}}{{.}}{{/gitUserId}}{{^gitUserId}}YOUR_USERNAME{{/gitUserId}}/{{#gitRepoId}}{{.}}{{/gitRepoId}}{{^gitRepoId}}{{projectName}}{{/gitRepoId}}
+then install it via:
+
+```shell
+    npm install {{#gitUserId}}{{.}}{{/gitUserId}}{{^gitUserId}}YOUR_USERNAME{{/gitUserId}}/{{#gitRepoId}}{{.}}{{/gitRepoId}}{{^gitRepoId}}{{projectName}}{{/gitRepoId}} --save
+```
+
+### For browser
+
+The library also works in the browser environment via npm and [browserify](http://browserify.org/). After following
+the above steps with Node.js and installing browserify with `npm install -g browserify`,
+perform the following (assuming *main.js* is your entry file):
+
+```shell
+browserify main.js > bundle.js
+```
+
+Then include *bundle.js* in the HTML pages.
+
+### Webpack Configuration
+
+Using Webpack you may encounter the following error: "Module not found: Error:
+Cannot resolve module", most certainly you should disable AMD loader. Add/merge
+the following section to your webpack config:
+
+```javascript
+module: {
+  rules: [
+    {
+      parser: {
+        amd: false
+      }
+    }
+  ]
+}
+```
+
+## Getting Started
