If you use version 2.0.0 or above you will need redis!
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pacman -S redis && systemctl start redis
|
||||||
|
```
|
||||||
|
|
||||||
|
With this redis will be downloaded and started.
|
||||||
|
Don't forget to enable the service if you don't want to start it every time you run the program.
