+# Frequently asked questions
+
+## Should I use this library?
+
+There are multiple ways to add FontAwesome icons to your Angular project, to name a few:
+
+1. An Angular component which aims to offer the best Angular experience: `ng add`, type checking, etc.
+2. FontAwesome SVG Core which Angular component uses under the hood. It is more flexible in some situations, but does
+   not offer the above features.
+3. FontAwesome Free/Pro.
+4. [Font Awesome Kits](https://fontawesome.com/kits).
+
+Depending on your needs, you may want to use this library or another method.
+
+For an average Angular project we recommend this library. It would feel the most natural. If occasionally you need more
+flexibility, it can be achieved
+following [this guide](https://github.com/FortAwesome/angular-fontawesome/blob/master/docs/guide/advanced-uses.md#replace-i-tags-with-icons-in-the-arbitrary-html).
+
+For a project where most of the icons are dynamic (e.g. a CMS project) and come in `<i>` form, you may have better luck
+to give up on type-checking and go with FontAwesome SVG Core or FontAwesome Free/Pro (in particular if you need some
+rarely used features only available to Web Fonts).
+
+If you're a Pro-user, you can also use the [Font Awesome Kits](https://fontawesome.com/kits) (specifically Kit NPM
+packages) with this library. This way you reduce the footprint of the icons in the `node_modules`, reduce work spent on
+removing unused icons from the bundle and get a convenient way to manage your custom icons. However, it will come with
+the cost of managing icons separately from the codebase.
