 # Strapi plugin mux
 
-A quick description of mux.
+## Summary
+
+A [Strapi](https://strapi.io/) plugin for managing uploads to [Mux](https://mux.com).
+
+This plugin provides the ability to upload content via a url or a direct file upload to [Mux](https://mux.com).
+
+## Install
+
+```
+npm i strapi-plugin-mux-video-uploader
+```
+
+or
+
+```
+yarn add strapi-plugin-mux-video-uploader
+```
+
+## Usage
+
+### Dependencies
+
+- A [Mux](https://mux.com) account
+- You will need both the **Access Token** and **Secret Key** scoped with "Full Access" permissions which can be created in the [Mux Dashboard](https://dashboard.mux.com/settings/access-tokens)
+- The **Webhook Signing Secret** which can be created in the [Mux Dashboard](https://dashboard.mux.com/settings/webhooks) (See the [Webhooks](#Webhooks) section for more info)
+
+### Webhooks
+
+When setting up your Webhook configuration in the [Mux Dashboard](https://dashboard.mux.com/settings/webhooks), the "URL to notify" field should be in the format of—
+
+```
+{STRAPI_BASE_URL}/mux-video-uploader/webhook-handler
+```
+
+Where `{STRAPI_BASE_URL}` is the publicly accessible hostname of your [Strapi](https://strapi.io/) instance.
+
+### Configuration
+
+In order for this plugin to communicate with [Mux](https://mux.com), some configuration values need to be set for the plugin before it can be used.
+
+With your **Access Token**, **Secret Key** and **Webhook Signing Secret**, navigate to the Settings view within [Strapi](https://strapi.io/) and click the "General" section under **MUX VIDEO UPLOADER**.
+
+On this view, set the appropriate values to their fields and click the Save button.
+
+### Permissions
+
+*TBD*
+
+## Features
+
+- Upload videos using a url or a file to [Mux](https://mux.com) from inside of [Strapi](https://strapi.io/)
+- [Mux](https://mux.com) updates [Strapi](https://strapi.io/) when the asset is ready
+- A `MuxAsset` content-type is provided to track asset readiness and that can be referenced by other [Strapi](https://strapi.io/) content-types

+
+## FAQ
+
+#### My Strapi instance is not publically available, can I still use Webhooks?
+
+Yes!  However, in order to make it work, you'll need a "Webhook Relay" that runs from within your network.  You can use a Webhook Relay service like Smee (https://smee.io/) or ngrok (https://ngrok.com/) to forward Webhook events to an instance of [Strapi](https://strapi.io/) behind a firewall.
