 # Daily operations
 
+## Edit your dotfiles
+
+Edit a dotfile with:
+
+```console
+$ chezmoi edit $FILENAME
+```
+
+This will edit `$FILENAME`'s source file in your source directory. chezmoi will
+not make any changes to the actual dotfile until you run `chezmoi apply`.
+
+To automatically run `chezmoi apply` when you quit your editor, run:
+
+```console
+$ chezmoi edit --apply $FILENAME
+```
+
+To automatically run `chezmoi apply` whenever you save the file in your editor, run:
+
+```console
+$ chezmoi edit --watch $FILENAME
+```
+
+You don't have to use `chezmoi edit` to edit your dotfiles. For more
+information, see [Do I have to use `chezmoi edit` to edit my
+dotfiles?](frequently-asked-questions/usage.md#how-do-i-edit-my-dotfiles-with-chezmoi)
