 ### Browser support
 
 This library will always have the previous year as its target. For 2021 for example the target will be ES2020.
-It always provides both a `UMD` (`.js`) and `.mjs` version. If you want to support legacy browsers, please use the feature of your bundler to transpile dependencie. In case of webpack and babel (give [vite](https://vitejs.dev/) a try, it's awesome) you'll have to install corresponding plugins such as [babel-plugin-proposal-optional-chaining](https://babeljs.io/docs/en/babel-plugin-proposal-optional-chaining) and include the dependency from `node_modules` which is normally entirely excluded from being processed.

 I do this to provide maximum flexibility and give those who target ESNext a chance to make full use of how this library is bundled.
 Everything else is just a matter of configuration :)
 
+### Is this library the right choice for me?
+
+Viselect primarily focuses on being a high-performant engine to select elements with various boundaries, behaviours and modes in your browser.
+Viselect is to "full-blown libraries" what is [popper.js](https://popper.js.org/) to [tippy.js](https://atomiks.github.io/tippyjs/) - the _core_ of your feature / of another
+library.
