+## Ryver Notifications
+* **Source**: https://ryver.com/
+* **Icon Support**: Yes
+* **Message Format**: TEXT
+* **Message Limit**: 1000 Characters per message
+
+### Account Setup
+To use Ryver you'll need to have the forum(s) you intend to notify already pre-created.  You'll need to do this before you follow the next set of instructions.
+ 
+Next you need to define a new webhook and get the corresponding URL.  This is done through:
+1. click on the **Integrations** > **Incoming Webhooks** beneath your settings on the left
+2. click on the **Create Webhook** button
+3. choose either **Slack** or **Plain/text Ryver** as this plugin currently supports both.
+4. Regardless of what webhook type you choose to create (Slack or Ryver), the next steps are still the same:
+    - Set the webhook type to **Chat Message**
+    - Select the forum(s) you already have set up to allow this webhook to access.
+    - Click next.
+
+ When you've completed this process you will receive a URL that looks something like this:
+```https://apprise.ryver.com/application/webhook/ckhrjW8w672m6HG```
+
+This effectively equates to:
+```https://{organization}.ryver.com/application/webhook/{token}```
+
+The last part of the URL you're given is the token we're most interested in. With respect to the above example, the **token** is ```ckhrjW8w672m6HG``` and the organization is **apprise**.
+
+### Syntax
+Valid syntaxes are as follows:
+* **ryver**://**{organization}**/**{token}**/
+* **ryver**://**{user}**@**{organization}**/**{token}**/
+* **ryver**://**{organization}**/**{token}**/?webhook=slack
+
+### Parameter Breakdown
+| Variable    | Required | Description
+| ----------- | -------- | -----------
+| organization| Yes      | The organization you created your webhook under.
+| token       | Yes      | The token provided to you after creating a *incoming-webhook*
+| user        | No       | Set the display name the message should appear from.
+| webhook     | No       | The type of webhook you created (Slack or Ryver). The only possible values are **slack** and **ryver**. The default value is **ryver** if the webhook value isn't specified.
