+[Podman](https://podman.io/) lets you run containerized applications in a rootless fashion. Containers are loosely isolated environments that are lightweight and contain everything needed to run the application, so there's no need to rely on what's installed on the host.

+> [!IMPORTANT]
+> These instructions assume that you are on a systemd based distro with [podman](https://podman.io/). If not, follow these [instructions on podman's website](https://podman.io/docs/installation) for how to do so. 
+> It also assumes you have used `loginctl enable-linger <username>` to enable the service to start for your user without logging in. 
+
+Copy the `redlib.container` and `.env.example` files to `.config/containers/systemd/` and modify any relevant values (for example, the ports Redlib should listen on, renaming the .env file and editing its values, etc.).
+
+To start Redlib either reboot or follow the instructions below:
+
+Notify systemd of the new files
+```bash
+systemctl --user daemon-reload
+```
+
+Start the newly generated service file
+
+```bash
+systemctl --user start redlib.service
+```
+
+You can check the status of your container by using the following command:
+```bash 
+systemctl --user status redlib.service
+```
