+# Hyprshot
+
+Hyprshot is an utility to easily take screenshot in Hyprland using your mouse.
+
+It allows taking screenshots of windows, regions and monitors which are saved to a folder of your choosing and copied to your clipboard.
+
+## Installation
+
+### Manual
+
+To install manually, simply clone this repo and copy/symlink the `hyprshot` script to a folder in your `PATH`:
+
+```bash
+$ git clone https://github.com/Gustash/hyprshot.git Hyprshot
+$ ln -s $(pwd)/Hyprshot/hyprshot $HOME/.local/bin
+$ chmod +x Hyprshot/hyprshot
+```
+
+## Usage
+
+The simplest usage of Hyprshot is executing it with one of the available modes.
+
+For example, to screenshot an open window:
+
+```bash
+$ hyprshot -m window
+```
+
+You can also skip saving the screenshot to a file, copying it only to the clipboard:
+
+```bash
+$ hyprshot -m output --clipboard-only
+```
+
+## Configuration
+
+You can choose which directory Hyprshot will save screenshots in by setting an `HYPRSHOT_DIR` environment variable to your preferred location.
+
+If `HYPRSHOT_DIR` is not set, Hyprshot will attempt to save to `XDG_PICTURES_DIR` and will further fallback to your home directory if this is also not available.
