+## Nextcloud Talk Notifications
+* **Source**: https://nextcloud.com/talk
+* **Icon Support**: No
+* **Message Format**: Text
+* **Message Limit**: 32000 Characters per message
+
+### Account Setup
+The official [Nextcloud Talk app](https://github.com/nextcloud/spreed) will need to be installed.  An 'app password' (also referred to as 'device-specific' password/token) of one member of the chat will need to be created, see the [documentation](https://docs.nextcloud.com/server/stable/user_manual/session_management.html#managing-devices) for more information.  Don't forget to disable file system access for this password.  
+
+### Syntax
+Secure connections (via https) should be referenced using **nctalks://** where as insecure connections (via http) should be referenced via **nctalk://**.
+
+Valid syntaxes are as follows:
+* `nctalk://{user}:{password}@{hostname}/{room_id}`
+* `nctalk://{user}:{password}@{hostname}:{port}/{room_id}`
+* `nctalks://{user}:{password}@{hostname}/{room_id}`
+* `nctalks://{user}:{password}@{hostname}:{port}/{room_id}`
+
+You can post in multiple chats by simply chaining them at the end of the URL.
+* `nctalk://{user}:{password}@{hostname}:{port}/{room_id1}/{room_id2}/{room_id3}`
+* `nctalks://{user}:{password}@{hostname}:{port}/{room_id1}/{room_id2}/{room_id3}`
+
+
+### Parameter Breakdown
+| Variable    | Required | Description
+| ----------- | -------- | -----------
+| hostname    | Yes      | The hostname of the server hosting your Nextcloud service.
+| user        | Yes      | The user of the nextcloud service you have set up.
+| password    | Yes      | The password associated with the **user** for your Nextcloud account.
+| room_id      | Yes      | The room_id of Nextcloud Talk.
+
+#### Example
+Send a secure nextcloud talk message to the room _93nfkdn3_:
+```bash
+# Assuming our {host} is localhost
+# Assuming our {user} is user1
+# Assuming our (user1) {password} is 12345-67890-12345-67890-12345:
+apprise nctalks://user1:12345-67890-12345-67890-12345@localhost/93nfkdn3
+```
+
+### Header Manipulation
+Some users may require special HTTP headers to be present when they post their data to their server.  This can be accomplished by just sticking a hyphen (**-**) in front of any parameter you specify on your URL string.
+```bash
+# Below would set the header:
+#    X-Token: abcdefg
+#
+# We want to send an insecure connection (we'll use ncloud://)
+# Assuming our {host} is localhost
+# Assuming our {user} is user1
+# Assuming our (user1) {password} is 12345-67890-12345-67890-12345
+# We want to notify Room _93nfkdn3_:
+apprise -vv -t "Test Message Title" -b "Test Message Body" \
+   nctalks://user1:12345-67890-12345-67890-12345@localhost/93nfkdn3?-X-Token=abcdefg
+
+# Multiple headers just require more entries defined with a hyphen in front:
+# Below would set the headers:
+#    X-Token: abcdefg
+#    X-Apprise: is great
+#
+# Assuming our {host} is localhost
+# Assuming our {user} is user1
+# Assuming our (user1) {password} is 12345-67890-12345-67890-12345
+# We want to notify Room _93nfkdn3_:
+apprise -vv -t "Test Message Title" -b "Test Message Body" \
+   nctalks://user1:12345-67890-12345-67890-12345@localhost/arnold?-X-Token=abcdefg&-X-Apprise=is%20great
