+# Frappuccino
+
+A dirty response to dev's skill issues in installing Caffeine
+
+## What is Frappuccino?
+
+Following the Caffeine, Espresso and so on trend, Frappuccino is probably the most lightweight way to keep your Linux system awake forcefully.
+
+## Why not Caffeine?
+
+I am aware that this is probably just a problem of mine, but I can't seem to install Caffeine on Arch for some obscure reason so I wrote my version.
+
+## How does it work?
+
+Frappuccino is just a quick wrapper around systemd-inhibit that creates a service and an infinite 2-seconds loop logging in the service logs.
+The logging loop is the argument to systemd-inhibit that will thus prevent any shutdown/sleep/hibernation to happen.
+
+## Is it safe / compatible with ...?
+
+Honestly, who knows. But being an innocent script and provided you don't have any other frappuccino named services, the worse that can happens is that it does not work.
+
+## Installation
+
+Clone or download this repository in your /home/username/ directory.
+
+    cd
+    git clone https://github.com/thecookingsenpai/frappuccino
+    cd frappuccino
+
+Now give the installation file the right permissions and execute it:
+
+    chmod +x install.sh
+    ./install.sh
+
+Done!
+
+## Management
+
+To inspect the service:
+
+    sudo systemctl status frappuccino
+
+This should show you some logs lines with the most recent timestamp.
+
+To start/stop the service:
+
+    sudo systemctl start frappuccino
+    sudo systemctl stop frappuccino
+    sudo systemctl restart frappuccino
+
+The service is automatically enabled for autostart. You can remove it with:
+
+    sudo systemctl disable frappuccino
+
+And, vice versa:
+
+    sudo systemctl enable frappuccino
+
+## Performances and workload
+
+Having a 2 seconds sleep, this script is basically guaranteed to have 0 impact on performance even on small systems like a Raspberry Pi 0 (on which I am aware isn't needed but you get the point).
