+** Fish shell and ansi-term
+Making =fish= shell to work with =ansi-term= may be a challenge, here are
+some pointers to save you time to setup your environment correctly.
+
+First be sure =~/.terminfo= is setup correctly by running:
+
+#+BEGIN_SRC fish
+tic -o ~/.terminfo $TERMINFO/e/eterm-color.ti
+#+END_SRC
+
+You can locate the =eterm-colors.ti= file with:
+
+#+BEGIN_SRC fish
+locate eterm-color.ti
+#+END_SRC
+
+Then setup your fish configuration file (usually at =~/.config/fish/config.fish=)
+
+#+BEGIN_SRC fish
+# emacs ansi-term support
+if test -n "$EMACS"
+  set -x TERM eterm-color
+end
+
+# this function may be required
+function fish_title
+  true
+end
+#+END_SRC
+
+Finally you may need to toggle truncated lines for some prompts to work
+correctly, in the function =dotspacemacs/user-config= of your dotfile add:
+
+#+BEGIN_SRC emacs-lisp
+(add-hook 'term-mode-hook 'toggle-truncate-lines)
+#+END_SRC
+
 * Eshell
 Some advanced configuration is setup for =eshell= in this layer:
