# Getting Started
Oh My Fish includes a small utility `omf` to fetch and install new packages and themes.
#### `omf update` _`[omf]`_ _`[...]`_
Update the framework and installed packages.
- When called without arguments, update core and all installed packages.
- You can choose to update only the core, by running `omf update omf`.
- For selective package update, list only the names of packages you wish to
update. You may still include "omf" in the list to update the core as well.
#### `omf install` _`[|]`_
Install one _or more_ packages.
- You can install packages directly by URL via `omf install URL`
- When called without arguments, install missing packages from [bundle](#dotfiles).
#### `omf list`
List installed packages.
#### `omf theme` _``_
Apply a theme. To list available themes, type `omf theme`. You can also [preview available themes](./docs/Themes.md) before installing.
#### `omf remove` _``_
Remove a theme or package.
> Packages subscribed to `uninstall_` events are notified before the package is removed, so custom cleanup of resources can be done. See [Uninstall](/docs/en-US/Packages.md#uninstall) for more information.
#### `omf reload`
Reload Oh My Fish and all plugins by using `exec` to replace current shell process with a brand new.
> This command try to be as safe as possible, mitigating side-effects caused by `exec` and preventing the reload in case of background processes.
#### `omf new pkg | theme` _``_
Scaffold out a new package or theme.
> This creates a new directory under `$OMF_CONFIG/{pkg | themes}/` with a template.
#### `omf submit` _`pkg/`_ _`[]`_
Add a new package. To add a theme, use `omf submit` _`themes/`_ _``_.
Make sure to [send us a PR][omf-pulls-link] to update the registry.
#### `omf doctor`
Use to troubleshoot before [opening an issue][omf-issues-new].
#### `omf destroy`
Uninstall Oh My Fish.
## Advanced
Oh My Fish installer places its startup code in your fish config file (`~/.config/fish/config.fish`).
### Startup
Every time you open a new shell, the startup code initializes Oh My Fish installation path and the _config_ path (`~/.config/omf` by default), sourcing the [`init.fish`](init.fish) script afterwards, which autoloads packages, themes and your custom init files.
For more information check the [FAQ](docs/en-US/FAQ.md#what-does-oh-my-fish-do-exactly).
### Dotfiles
The `$OMF_CONFIG` directory represents the user state of Oh My Fish. It is the perfect
candidate for being added to your dotfiles and/or checked out to version control. There are four important files:
- __`theme`__ - The current theme
- __`bundle`__ - List of currently installed packages/themes
- __`init.fish`__ - Custom script sourced after shell start
- __`before.init.fish`__ - Custom script sourced before shell start
It's highly recommended that your custom startup commands go into `init.fish` file instead of `~/.config/fish/config.fish`, as this allows you to keep the whole `$OMF_CONFIG` directory under version control.
If you need startup commands to be run *before* Oh My Fish begins loading plugins, place them in `before.init.fish` instead. If you're unsure, it is usually best to put things in `init.fish`.
#### About the bundle
Every time a package/theme is installed or removed, the `bundle` file is updated. You can also edit it manually and run `omf install` afterwards to satisfy the changes. Please note that while packages/themes added to the bundle get automatically installed, a package/theme removed from bundle isn't removed from user installation.
## Creating Packages
Oh My Fish uses an advanced and well defined plugin architecture to ease plugin development, including init/uninstall events and function autoloading. [See the documentation](docs/en-US/Packages.md) for more details.
