+
+* Description
+An interface to a Transmission session for GNU Emacs.
+
+* Install
+To use this configuration layer, add it to your =~/.spacemacs=. You will need to
+install and configure =transmission-daemon=. Debian example:
+#+BEGIN_SRC sh
+sudo apt-get -y install transmission-daemon
+sudo service transmission-daemon stop
+#+END_SRC
+Set =rpc-authentication-required= to false (or 0 if it is numeric)
+in /etc/transmission-daemon/settings.json or
+configure authorization.
+See transmission.el [[https://github.com/holomorph/transmission][README.org]] for details.
+Start the daemon:
+#+BEGIN_SRC sh
+sudo service transmission-daemon start
+#+END_SRC
+
+* FAQ
+** How to enable status auto refresh?
+Add  =(transmission :variables transmission-auto-refresh-all t)= to
+=dotspacemacs-configuration-layers= or pick modes manually:
+#+BEGIN_SRC emacs-lisp
+(setq transmission-refresh-modes '(transmission-mode
+                                   transmission-files-mode
