 ## Troubleshooting
 
+- **The distro/theme greeting still shows** (CachyOS, Oh My Fish, …): those
+  configs define `fish_greeting` while the shell starts, which beats
+  autoloading. Check what fish resolved:
+  `functions --details fish_greeting` — it must point at
+  `~/.config/fish/functions/fish_greeting.fish`. If it points at a distro
+  file, run `fish install.fish` again (it adds the source block to
+  `config.fish`) or add it yourself:
+  ```fish
+  if test -f ~/.config/fish/functions/fish_greeting.fish
+      source ~/.config/fish/functions/fish_greeting.fish
