     Add the following lines to your bash or zsh config (e.g. ~/.bash_profile):
-      if [ -f $(brew --prefix)/bin/liquidprompt ]; then
-        . $(brew --prefix)/bin/liquidprompt
+      if [ -f #{HOMEBREW_PREFIX}/share/liquidprompt ]; then
+        . #{HOMEBREW_PREFIX}/share/liquidprompt
       fi
 
     If you'd like to reconfigure options, you may do so in ~/.liquidpromptrc.
     A sample file you may copy and modify has been installed to
-      #{HOMEBREW_PREFIX}/share/liquidprompt/liquidpromptrc-dist
+      #{HOMEBREW_PREFIX}/share/liquidpromptrc-dist
 
     Don't modify the PROMPT_COMMAND variable elsewhere in your shell config;
     that will break things.
