Question on the Usage section

[iamwill123]

Probably a dumb question but in the usage section:

import Vue from 'vue'
import VueMediaEmbed from 'vue-media-embed'
import Vuex from 'vuex'

Vue.use(Vuex)
const store = new Vuex.Store({ ... })

Vue.use(VueMediaEmbed, { store })

What am I storing in the store?? do you have an example?
If I am using multiple mediaIds...
<vue-media-embed source="soundcloud://319412512" :auto-play="1" :allow-fullscreen="0" />
in my template.

Thanks,
Will
