+*** How can I change or define an alias for an =evil-leader= prefix ?
+It is possible to change an =evil-leader= prefix by binding its keymap to
+another sequence. For instance, if you want to switch ~SPC l~
+(=evil-avy-goto-line=) with ~SPC L~ (=perspectives= layer) to make the later
+easier to reach, you can use:
+
+#+begin_src emacs-lisp
+(evil-leader/set-key
+  "l" (lookup-key evil-leader--default-map "L")
+  "L" 'evil-avy-goto-line)
+#+end_src
+
+*** Should I place my settings in =user-init= or =user-config=?
+
+Any variable that layer configuration code will *read* and *act on* must be set
+in =user-init=, and any variable that Spacemacs explicitly sets but you wish to
+*override* must be set in =user-config=.
+
+Anything that isn't just setting a variable should 99% be in =user-config=.
