 It is best to modify your shell startup files to set the `VISUAL` or `EDITOR` environment variables. Git requires no configuration to use them, and they can be used by other programs too.
+{{{
+#!sh
+# Bourne shell (sh) and relatives
+export VISUAL
+VISUAL=nano
+}}}
+{{{
+#!csh
+# C shell (csh) and relatives
+setenv VISUAL nano
+}}}
 
 If for some reason you want to override `VISUAL`/`EDITOR` and use a different editor with Git, you can specify it in `$HOME/.gitconfig`:
 {{{
+#!sh
 $ git config --global core.editor ed
 }}}
