## Configuration
The Fish configuration is stored in `~/.config/fish/`. The main configuration file is `~/.config/fish/config.fish`. You can also have a `~/.config/fish/functions/` directory to store your functions, and a `~/.config/fish/completions/` directory to store your completions. There's also a `~/.config/fish/conf.d/` directory to store your drop-in configuration files.

There's also a `~/.config/fish/conf.d/` directory to store your drop-in configuration files which gets sourced when Fish starts.

### Aliases
Aliases use a slightly different syntax in Fish. Here's an example of a few aliases that I use:
{% raw %}
```sh
# Use `eza` instead of `ls`
alias ls "eza"
# Upload Gists
alias gist "gh gist create"
# Some ls aliases
alias ll 'eza -l'
alias la 'eza -la'
alias l 'eza -hF'
```
{% endraw %}
So, just migrate your aliases and put the resulting file(s) in `~/.config/fish/conf.d/`.
### Completions
Fish automatically searches through any directories in the list variable `$fish_complete_path`, and any completions defined are automatically loaded when needed. Most software already have Fish completions, but if you need to create your own, see the [official documentation](https://fishshell.com/docs/current/completions.html).
### Plugins
Fish has a nice plugin system, you can use [Fisher](https://github.com/jorgebucaran/fisher) to manage your plugins. It's very easy to use, and you can install plugins with a single command. Here's a list of some plugins that I use:
