*Note*: Instant prompt requires Zsh >= 5.4. It's OK to enable it even when using an older version of
Zsh but it won't do anything.

### How do I initialize direnv when using instant prompt?
If you've enabled [instant prompt](#instant-prompt), you should have these lines at the top of
`~/.zshrc`:
```zsh
if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
fi
```
To initialize direnv you need to add one line above that block and one line below it.
```zsh
(( ${+commands[direnv]} )) && emulate zsh -c "$(direnv export zsh)"
if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
fi
(( ${+commands[direnv]} )) && emulate zsh -c "$(direnv hook zsh)"
```

### How do I export GPG_TTY when using instant prompt?
You can set `GPG_TTY` like this anywhere in `~/.zshrc`:
```zsh
export GPG_TTY=$TTY
```
This works whether you are using [instant prompt](#instant-prompt) or not. It works even if you
aren't using powerlevel10k. As an extra bonus, it's much faster than the commonly used
`export GPG_TTY=$(tty)`.
