UpDownUpDown provides two template tags for adding up/down voting for any post or comment. Anonymous guest visitors can either be allowed to vote (tracked by ip address) or be denied voting and shown a view-only vote count badge. Votes are registered on the server without refreshing the page.

This plugin uses build tools to compile and minify JavaScript and SCSS files for production.
The uncompressed, human-readable source code can be found in the following directory within the plugin: 
* <code>assets/src/</code> (contains JavaScript and SCSS source files)
The compiled, production-ready files are output to: 
* <code>assets/dist/</code>
To build the production assets yourself: 
1. Navigate to the root directory of the plugin. 
2. Run <code>npm install</code> to install dependencies. 
3. Run <code>npm run build</code> to compile the assets into the <code>assets/dist/</code> directory.
