title: Day 0 - Planning

---

In order to set yourself up to success it's useful to plan out your Bluefin installation into three distinct phases, mirroring the systems operations lifecycle. 

# Day 0 - Planning
Most pain points can be addressed directly by planning ahead of time.

### All Users
  - [ ] Is your hardware Linux friendly?
  - [ ] Does the hardware require an out of tree kernel module? 
  - [ ] Wireless card supported? 
  - [ ] Dedicated disk ready to go?
  - [ ] Do you understand the limitations of having an Nvidia GPU? 
  - [ ] Are the applications you use well supported on Flathub?
  - [ ] Read this documentation in its entirety
  - [ ] [Homebrew](https://docs.brew.sh/) documentation
  - [ ] [Flathub](https://docs.flathub.org/) documentation
  - [ ] [rpm-ostree](https://coreos.github.io/rpm-ostree/) documentation
  - [ ] [bootc](https://containers.github.io/bootc/) documentation - this is a future tool that is currently included but not being used for important tasks, it will replace rpm-ostree in the Fall of 2024

### Developers
 - [ ] Do you know [how to use containers](https://docker-curriculum.com/#introduction) for development? 
 - [ ] Do you know how to manage [systemd service units](https://systemd.io/) for both the system and user accounts?

# Day 1 - Deployment and Configuration

- Download the right ISO from the website
- Install the operating system
    * Use the entire disk with automatic partitioning
    * (Optional): Set up Secure Boot
    * (Optional): `ujust switch-channel` to move to `:stable` or `:latest` 
- Software Installation
    * Use GNOME Software to install Flatpaks
        + (Optional): Use Flatseal to manage Flatpak permissions if appropriate
    * (Optional): Install Command line applications via `brew`
- Post-installation Configuration
    * Select/Change default applications as you see fit
- Developers:
    * `ujust devmode` and follow the directions
    * `git clone` your project and ensure that Docker/Podman can build your application
    * Start VSCode and configure your settings and extensions

# Day 2 - Operations and Maintenance

Bluefin strives to make maintenance as easy as possible, however many of the automated tasks can be run manually. 

- Run a System Upgrade via the menu option or `ujust update` to observe an update and reboot
  - `ujust changelogs` will show incoming changes and updates coming from Fedora
- Subscribe to the announcements tag on the Universal Blue forums
- Use the Warehouse application to manage Flatpak lifecycle:
    * Pin to an old version or rollback
    * Easily remove applications at once
- `ujust clean-system` to clean up old containers and unused flatpak runtimes
