+# Setting up ntfy (optional)
+
+The playbook can install and configure the [ntfy](https://ntfy.sh/) push notifications server for you.
+
+Using the [UnifiedPush](https://unifiedpush.org) standard, ntfy enables self-hosted (Google-free) push notifications from Matrix (and other) servers to UnifiedPush-compatible matrix compatible client apps running on Android and other devices.
+
+This role is intended to support UnifiedPush notifications for use with the Matrix and Matrix-related services that this playbook installs. This role is not intended to support all of ntfy's other features.
+
+**Note**: In contrast to push notifications using Google's FCM or Apple's APNs, the use of UnifiedPush allows each end-user to choose the push notification server that they prefer.  As a consequence, deploying this ntfy server does not by itself ensure any particular user or device or client app will use it.
+
+
+## Adjusting the playbook configuration
+
+Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file (adapt to your needs):
+
+```yaml
+# Enabling it is the only required setting
+matrix_ntfy_enabled: true
+
+# Some other options
+matrix_server_fqn_ntfy: "ntfy.{{ matrix_domain }}"
+matrix_ntfy_configuration_extension_yaml: |
+  log_level: DEBUG
+```
+
+For a more complete list of variables that you could override, see `roles/matrix-ntfy/defaults/main.yml`.
+
+For a complete list of ntfy config options that you could put in `matrix_ntfy_configuration_extension_yaml`, see the [ntfy config documentation](https://ntfy.sh/docs/config/#config-options).
+
+
+## Installing
+
+Don't forget to add `ntfy.<your-domain>` to DNS as described in [Configuring DNS](configuring-dns.md) before running the playbook.
+
+After configuring the playbook, run the [installation](installing.md) command again:
+
+```
+ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
+```
+
+
+## Usage
+
+To make use of your ntfy installation, on Android for example, first you need to install the `ntfy` client app and configure it to point to your ntfy server, such as `https://ntfy.DOMAIN`. That is the only thing you need to do in the ntfy client app. (It has many other features, but for our purposes you can ignore them.)
+
+Then any UnifiedPush-enabled matrix app on that device will discover it and tell your matrix server to use your ntfy server to send push notifications to that matrix app.
+
+If the matrix app asks, "Choose a distributor: FCM Fallback or ntfy", then choose "ntfy".
+
+If the matrix app doesn't seem to pick it up, try restarting it and try the Troubleshooting section below.
+
+
+## Troubleshooting
+
+First check that the matrix client app you are using supports UnifiedPush. There may well be different variants of the app.
+
+Set the ntfy server's log level to 'DEBUG', as shown in the example settings above, and watch the server's logs with `sudo journalctl -fu matrix-ntfy`.
+
+To check if UnifiedPush is correctly configured on the client device, look at "Settings -> Notifications -> Notification Targets" in Element-Android or SchildiChat, or "Settings -> Notifications -> Devices" in FluffyChat. There should be one entry for each matrix client app that has enabled push notifications, and when that client is using UnifiedPush you should see a URL that begins with your ntfy server's URL. In Element-Android or SchildiChat, two URLs are shown: "push\_key" and "Url", and both should begin with your ntfy server's URL.
+
+If it is not working, useful tools are "Settings -> Notifications -> Re-register push distributor" and "Settings -> Notifications -> Troubleshoot Notifications" in SchildiChat (possibly also Element-Android). In particular the "Endpoint/FCM" step of that troubleshooter should display your ntfy server's URL that it has discovered from the ntfy client app.
+
+The simple [UnifiedPush troubleshooting](https://unifiedpush.org/users/troubleshooting/) app [UP-Example](https://f-droid.org/en/packages/org.unifiedpush.example/) can be used to manually test UnifiedPush registration and operation on an Android device.
