-Kills all applications. An attempt at making a simple one file app in Python.
-
-## Running
-
-Requires [GTK+-3.0](https://www.gtk.org/), [Granite](https://github.com/elementary/granite/), [PyGObject](https://pygobject.readthedocs.io/en/latest/) and [Python3](https://www.python.org/). Right click on KillSwitch and select 'Run' or run via `python3 KillSwitch`.
-
-## Adding to Applications Menu
-
-<b>With [AppEditor](https://github.com/donadigo/appeditor) (recommended):</b>
-
-1. Install [AppEditor](https://github.com/donadigo/appeditor).
-2. Download KillSwitch (store it somewhere where it won't be accidentally deleted, i.e. in `~/Scripts` for instance).
-3. Right click on KillSwitch and select "Create a Menu Entry".
-4. Configure it however you want.
-
-<b>Manual:</b>
-
-1. Download KillSwitch (store it somewhere where it won't be accidentally deleted, i.e. in `~/Scripts` for instance).
-2. Create a `com.github.pongloongyeat.killswitch.desktop` file in `~/.local/share/applications` with the following
-
-```
-[Desktop Entry]
-Type=Application
-Name=KillSwitch
-Exec=/path/to/KillSwitch
-Icon=/path/to/icon.svg
-```
-
-## Debugging
-
-Under the `AppInfo` class, comment out `os.system("pkill {}".format(self.exec_name))` and run via Terminal. Maybe a future, more feature-rich version that's not intended to be written in a single file can have a debugging flag/mode.
+A simple app to kill all applications.
