+# Telegram Notifier
+
+## What does it do?
+
+It checks your current telegram messages via
+`[telegram-cli]`(https://github.com/vysheng/tg) and notifies you about
+any potential messages.
+
+## Why?
+
+The Telegram Desktop client is somewhat ressource intensive, particularly
+on the CPU, leading to high(er) power consumption. With this lightweight
+notifier script, you are not required to have the desktop client running
+in the background at all times.
+
+## Are there system requirements?
+
+Yes.
+
+Checking Telegram Messages: `[telegram-cli]`(https://github.com/vysheng/tg)
+```
+# Debian
+apt install telegram-cli
+```
+
+Set it up via commandline:
+```
+telegram-cli
+```
+
+Sending Notifications: `gdbus` (likely installed already)
+
+## Use Telegram Notifier
+
+Make sure, you fullfill the above requirements and set up `telegram-cli`
+with your account.
+
+Pull this source directory, and run the Makefile:
+```
+git pull https://src.jayvii.de/Hobby/PinePhoneScripts
+cd PinePhoneScripts/telegram-notifier
+make install
+```
+
+This will place `telegram-notifier.sh` into `~/.local/bin/telegram-notifier.sh`
+and places the systemd-service file under your user's directory. You can enable
+& start telegram-notifier with:
+```
+systemctl --user enable telegram-notifier --now
+```
