# Running
First, install the package:
Installation:
```bash
git clone https://github.com/sezanzeb/key-mapper.git
cd key-mapper
sudo python3 setup.py install
usermod -a -G input $USER
```
To keep injecting the mapping after closing the window, the daemon needs to
be running:
be running. If it doesn't already after logging in, you can use:
```bash
sudo key-mapper-service -d
sudo key-mapper-service
```
To open the UI to modify the mappings, use:
```bash
sudo key-mapper-gtk -d
sudo key-mapper-gtk
```
You can also start it via your applications menu.
