Template Details
Sing App Lite is a free, reduced version of the commercial Sing App template. The repository is flatlogic/sing-app, built with HTML, Bootstrap 4.5, and SCSS. It offers a responsive layout and a set of styled Bootstrap components, making it a starting point for admin interfaces.
What the free version includes: dashboard example pages, typography, tables, notifications, basic charts, icons, maps, and a hover sidebar. Theme switching, login pages, and other additional pages are not included in the free version and require the full version.
The build process uses yarn: after cloning the repository, run yarn install to install dependencies, yarn build to output the /src source files to /dist, and yarn watch to monitor source file changes and recompile Handlebars templates and SCSS styles in real time. Pages must be accessed through a web server (such as Apache, nginx, or an IDE's built-in server); opening local files directly may cause some features to malfunction.
Regarding licensing, the code for this free version is under the MIT license, permitting use, modification, commercial use, and distribution, provided the copyright notice and license notice are retained when distributing. Third-party assets such as demo images, fonts, and icons require separate verification of their respective licenses; external services such as domains, hosting, and databases may incur additional costs.

Our heuristic uses license records (up to 30), a demo link (12), a preview (10), stars (15), recorded maintenance (15), description completeness (8), feature records (5) and classification data (5). It is not a code, security or performance test, or a Google score. A link does not establish tested functionality.

A demo link is listed. Check it with your own content and viewport sizes; its presence does not confirm that forms, authentication or payments work.
The catalog identifies HTML as the primary stack. Check the actual dependency manifest and lockfile for versions and hosting requirements. These notes use recorded metadata, not a code audit or a deployment test.

Building a project from scratch means that there is a lot of things to keep track of all at once: analytics, dynamic forms data, UI and UX elements, and much more. This simple admin template is well suited for web apps or any other website or project that requires admin dashboard. This template will serve as a solid foundation for your upcoming project and will save you a lot of time and, hence, money.
## Quick Start
#### 1. Get the latest version
You can start by cloning the latest version of Sing App Lite on your local machine by running:
```shell
$ git clone -o sing-app-lite -b master --single-branch \
https://github.com/flatlogic/sing-app.git MyApp
$ cd MyApp
```
#### 2. Run `yarn install`
This will install both run-time project dependencies and developer tools listed
in [package.json](../package.json) file. We are moving all dependencies to npm, so there will be no bower dependencies soon.
#### 3. Run `yarn build`
This command will build the app from the source files (`/src`) into the output
`/dist` folder. Then open `dist/index.html` in your browser.
Now you can open your web app in a browser, on mobile devices and start
hacking. The page must be served from a web server, e.g. apache, nginx, WebStorm built-in web server, etc., otherwise some features may not work properly.
#### 3. Run `yarn watch`
This command will watch for changes in `/src` and recompile handlebars' templates & scss styles on the fly into html & css accordingly.
