 If you want to test `k3se` you can use [Vagrant][website-vagrant]. All examples in the `examples/` folder can be used with the provided `Vagrantfile` that provisions 3 Ubuntu VMs. To bring up the VMs you can run the following command:
 
 ```bash
-$ make vagrant-up
+make vagrant-up
 ```
 
 Once you are done testing, you can destroy the VMs with the following command:
 
 ```bash
-$ make vagrant-down
+make vagrant-down
 ```
 
 ## Prerequisites 📝
 
 The nodes have to be accessible via SSH, either directly or via a bastion host. Further, the user on the remote nodes needs to have passwordless `sudo` set up. If this is not yet the case, you may manually do so via the following command:
 
 ```bash
-$ echo "$(whoami) ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/$(whoami)
+echo "$(whoami) ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/$(whoami)
 ```
