+
+[⬅️ Go back to main README](README.md)
+
+Sometimes scripts do not behave as expected. In these cases debug output
+or logs can help.
+
+## Debug output
+
+Run this command in a terminal:
+
+    :set PrintDebug true;
+
+You will then see debug output when running the script from terminal.
+
+To revert to default output run:
+
+    :set PrintDebug false;
+
+### Debug output for specific script
+
+Even having debug output for a specific script or function only (or a
+set of) is possible. To enable debug output for `telegram-chat` run:
+
+    :set ($PrintDebugOverride->"telegram-chat") true;
+
+## Debug logs
+
+The debug info can go to system log. To make it show up in `memory` run:
+
+    /system/logging/add topics=script,debug action=memory;
+
+Other actions (`disk`, `email`, `remote` or `support`) can be used as
+well. I do not recommend using `echo` - use [debug output](#debug-output)
+instead.
+
+Disable or remove that setting to restore regular logging.
+
+## Verbose output
+
+Specific scripts can generate huge amount of output. These do use a function
+`$LogPrintVerbose`, which is declared, but has no code, intentionally.
+
+If you *really* want that output set the function to be the same as
+`$LogPrint`:
+
+    :set LogPrintVerbose $LogPrint;
+
+To revert that change just run:
+
+    :set LogPrintVerbose;

+
+[⬅️ Go back to main README](../README.md)
+
+> ℹ️ **Info**: This script can not be used on its own but requires the base
+> installation. See [main README](../README.md) for details.
+
+Description
+-----------
+
+On *Cloud Hosted Router* (*CHR*) the licensing is perpetual: Buy once, use
+forever - but it needs regular renewal. This script checks licensing state
+and sends a notification to warn before expiration.
+
+### Sample notifications
+
+![check-perpetual-license notification warn](check-perpetual-license.d/notification-01-warn.avif)  
+![check-perpetual-license notification renew](check-perpetual-license.d/notification-02-renew.avif)
+
+Requirements and installation
+-----------------------------
+
+Just install the script:
+
+    $ScriptInstallUpdate check-perpetual-license;
+
+And add a scheduler for automatic update notification:
+
+    /system/scheduler/add interval=1d name=check-perpetual-license on-event="/system/script/run check-perpetual-license;" start-time=startup;
+
+Configuration
+-------------
+
+No extra configuration is required for this script, but notification
+settings are required for
+[e-mail](mod/notification-email.md),
+[gotify](mod/notification-gotify.md),
+[matrix](mod/notification-matrix.md),
+[ntfy](mod/notification-ntfy.md) and/or
+[telegram](mod/notification-telegram.md).
+
+Usage and invocation
+--------------------
+
+Be notified when run from scheduler or run it manually:
+
+    /system/script/run check-perpetual-license;
+
+Tips & Tricks
+-------------
+
+The script checks for full connectivity before acting, so scheduling at
+startup is perfectly valid:
+
+    /system/scheduler/add name=check-perpetual-license@startup on-event="/system/script/run check-perpetual-license;" start-time=startup;

+
+[⬅️ Go back to main README](../../README.md)
+
+> ℹ️️ **Info**: This module can not be used on its own but requires the base
+> installation. See [main README](../../README.md) for details.
+
+Description
+-----------
+
+This module adds support for sending notifications via
+[Gotify ↗️](https://gotify.net/). A queue is used to make sure
+notifications are not lost on failure but sent later.
+
+Requirements and installation
+-----------------------------
+
+Just install the module:
+
+    $ScriptInstallUpdate mod/notification-gotify;
+
+Also deploy the [Gotify server ↗️](https://github.com/gotify/server) and
+optionally install a Gotify client on your mobile device.
+
+Configuration
+-------------
+
+Follow the [Installation ↗️](https://gotify.net/docs/install) instructions
+and the [First Login ↗️](https://gotify.net/docs/first-login) setup. Once
+you have a user and account you can start creating apps. Each app is an
+independent notification feed for a device or application.
+
+![Create new app](notification-gotify.d/appsetup.avif)
+ 
+On creation apps are assigned a *Token* for authentification, you will need
+that in configuration.
+
+Edit `global-config-overlay`, add `GotifyServer` with your server address
+(just the address, no protocol - `https://` is assumed) and `GotifyToken`
+with the *Token* from your configured app on the Gotify server. Then reload
+the configuration.
+
+> ℹ️ **Info**: Copy relevant configuration from
+> [`global-config`](../../global-config.rsc) (the one without `-overlay`) to
+> your local `global-config-overlay` and modify it to your specific needs.
+
+For a custom service installing an additional certificate may be required.
+You may want to install that certificate manually, after finding the
+[certificate name from browser](../../CERTIFICATES.md).
+
+Usage and invocation
+--------------------
+
+There's nothing special to do. Every script or function sending a notification
+will now send it to your Gotify application feed.
+
+But of course you can use the function to send notifications directly. Give
+it a try:
+
+    $SendGotify "Subject..." "Body...";
+
+Alternatively this sends a notification with all available and configured
+methods:
+
+    $SendNotification "Subject..." "Body...";
+
+To use the functions in your own scripts you have to declare them first.
+Place this before you call them:
+
+    :global SendGotify;
+    :global SendNotification;
+
+In case there is a situation when the queue needs to be purged there is a
+function available:
+
+    $PurgeGotifyQueue;
