+Description
+-----------
+
+RouterOS and firmware are upgraded separately, activating the latter
+requires an extra reboot. This script handles upgrade and reboot.
+
+> ⚠️ **Warning**: This *should* be bullet proof, but I can not guarantee. In
+> worst case it has potential to cause a boot loop, so handle with care!
+
+Requirements and installation
+-----------------------------
+
+Just install the script and create a scheduler:
+
+    $ScriptInstallUpdate firmware-upgrade-reboot;
+    / system scheduler add name=firmware-upgrade-reboot on-event="/ system script run firmware-upgrade-reboot;" start-time=startup;
+
+Enjoy firmware being up to date and in sync with RouterOS.

+> ℹ️️ **Info**: This module can not be used on its own but requires the base

+
+Description
+-----------
+
+This module adds support for sending notifications via
+[Matrix](https://matrix.org/) via client server api. 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-matrix;
+
+Also install a Matrix client on at least one of your mobile and/or desktop
+devices and create an account.
+
+Configuration
+-------------
+
+Edit `global-config-overlay`, add `MatrixHomeServer`, `MatrixAccessToken` and
+`MatrixRoom`. Then reload the configuration.
+
+Usage and invocation
+--------------------
+
+There's nothing special to do. Every script or function sending a notification
+will now send it to your Matrix account.

+Description
+-----------
+
+This module adds support for sending notifications via
+[Telegram](https://telegram.org/) via bot api. 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-telegram;
+
+Also install Telegram on at least one of your mobile and/or desktop devices
+and create an account.
+
+Configuration
+-------------
+
+Open Telegram, then start a chat with [BotFather](https://t.me/BotFather) and
+create your own bot:
+
+![create new bot](notification-telegram.d/newbot.avif)
+
+Now open a chat with your bot and start it by clicking the `START` button.
+
+Open just another chat with [GetIDs Bot](https://t.me/getidsbot), again start
+with the `START` button. It will send you some information, including the
+`id`, just below `You`.
+
+Finally edit `global-config-overlay`, add `TelegramTokenId` with the token
+from *BotFather* and `TelegramChatId` with your id from *GetIDs Bot*. Then
+reload the configuration.
+
+### Notifications to a group
+
+Sending notifications to a group is possible as well. Add your bot and the
+*GetIDs Bot* to a group, then use the group's id (which starts with a dash)
+for `TelegramChatId`. Then remove *GetIDs Bot* from group.
+
+Usage and invocation
+--------------------
+
+There's nothing special to do. Every script or function sending a notification
+will now send it to your Telegram account.
