+# Save Your Eyes (SYE)
+
+Generates a bash script which will notify you
+when you spend too much time working on PC.
+
+Delay between notifications depends on your age
+(this feature is commonly for children).
+
+## Install
+```bash
+git clone https://codeberg.org/DarkCat09/saveyoureyes.git
+cd saveyoureyes
+chmod +x install.sh
+./install.sh
+```
+
+### 1. Time
+Delay is set to the safe time according to the table below.
+|  Age  |Safe|Warning|
+|:-----:|:--:|:-----:|
+| 5 - 7 | 10 |  30   |
+| 8 - 11| 15 |  45   |
+|12 - 13| 20 |  60   |
+|14 - 15| 25 |  80   |
+|16 - 17| 30 |  90   |
+|  18+  | 60 |  90   |
+
+### 2. Exclusions
+You can add some applications to whitelist/exclusions.  
+When they are in processes list, notifications won't appear.
+
+For exmaple, add vlc to disable script while you're watching a film.
+
+### 3. Text and type
+Enter notification text, title, and choose how script should send it.  
+Here are some exmaples:
+|Description|Screenshot|
+|:----------|:--------:|
+|**GtkDialog:** opens dialog using python module [https://codeberg.org/DarkCat09/showdialog](showdialog).|![Picture 1](https://i.ibb.co/qDPX20K/gtkdialog.png)|
+|**libnotify:** executes notify-send command.|![Picture 2](https://i.ibb.co/5syChrV/notifysend.png)|
+|**Open browser:** opens [a simple web page](https://codeberg.org/DarkCat09/pages/src/branch/main/text/index.html) using xdg-open.|![Picture 3](https://i.ibb.co/vhRsrFq/browser.png)|
+
+### 4. Build and add to crontab
+Then, the script will be generated from `.template.sh` and written to `~/.sye.sh`.  
+If you want, it can automatically update crontab to run sye.sh after system boot.
+
+But I recommend to use "Autorun" from KDE Settings if you are using Plasma. It works much better.
