Thanks for taking this and running with it, @chteuchteu 😃 Definitely better than I could have managed.

I'd still like to see a standalone version for those that don't use NPM, though.

@PeterShaggyNoble The pleasure is mine! :-)

In order to avoid requiring npm/yarn, we'd have to publish MaterialDesign-SVG as composer package.
@Templarian : it's quite simple actually, all you have to do is to add a composer.json file in the project root dir, and publish it on packagist (https://packagist.org/).

Once done, GitHub will tell packagist when a new release is tagged and voilà!

This would allow us to skip the "withIconsPath" step:

Mdi::withIconsPath(__DIR__.'/../../../node_modules/@mdi/svg/svg/');

since we already know the vendor/ (composer's node_modules) relative path.

@Templarian : do you want me to open a new PR with the composer.json file? We'd have to create an account for MDI on packagist.

@chteuchteu Yea, we'll need to do that I suppose. Lets shoot to get this setup this weekend.

Nice! :)

@Templarian : I opened a PR with a shiny composer.json: Templarian/MaterialDesign-SVG#8
