Installation

ember install flexi

That's all that required if you're using the classic component layout. If using a pods, install the shim for ember-app in your ember-cli-build.js file.

var EmberApp = require('ember-cli/lib/broccoli/ember-app');
var shim = require('@html-next/flexi-layouts/lib/pod-templates-shim');

shim(EmberApp);

This shim makes ember-cli's template tree able to find the templates for layouts.
