# podman
# Podman
Podman is a lightweight container manager that allows users to manage and run containers without requiring a daemon, providing flexibility and security for containerized applications.
## Using Podman in VLang
To get started
The following example demonstrates how to use the Podman installer in a VLang script. It checks if Podman is installed, removes it if found, or installs it if not.
### Example Code (VLang)
```vlang
import freeflowuniverse.herolib.installers.virt.podman as podman_installer
mut podman_installer0:= podman_installer.get()!
podman_installer0.destroy()! //will remove all
podman_installer0.install()!
mut podman := podman_installer.get()!
if podman.installed() {
podman.destroy()!
} else {
podman.install()!
}
```
