+Reloading powerline after update
+================================
+
+Once you have updated powerline you generally have the following options:
+
+#. Restart the application you are using it in. This is the safest one. Will not 
+   work if the application uses ``powerline-daemon``.
+#. For shell and tmux bindings (except for zsh with libzpython): do not do 
+   anything if you do not use ``powerline-daemon``, run ``powerline-daemon 
+   --replace`` if you do.
+#. Use powerline reloading feature.
+
+    .. warning::
+      This feature is an unsafe one. It is not guaranteed to work always, it may 
+      render your Python constantly error out in place of displaying powerline 
+      and sometimes may render your application useless, forcing you to 
+      restart.
+
+      *Do not report any bugs occurred when using this feature unless you know 
+      both what caused it and how this can be fixed.*
+
+   * When using zsh with libzpython use
+
+     .. code-block:: bash
+
+        powerline-reload
+
+     .. note:: This shell function is only defined when using libzpython.
+
+   * When using IPython use
+
+     ::
+
+        %powerline reload
+
+   * When using Vim use
+
+     .. code-block:: Vim
+
+        py powerline.reload()
+        " or (depending on Python version you are using)
+        py3 powerline.reload()
