+### 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)`.
