+Tips and tricks for powerline developers
+****************************************
+
+Profiling powerline in Vim
+==========================
+
+Given that current directory is the root of the powerline repository the
+following command may be used:
+
+.. code-block:: sh
+
+ vim --cmd 'let g:powerline_pyeval="powerline#debug#profile_pyeval"' \
+ --cmd 'set rtp=powerline/bindings/vim' \
+ -c 'runtime! plugin/powerline.vim' \
+ {other arguments if needed}
+
+After some time run ``:WriteProfiling {filename}`` Vim command. Currently this
+only works with recent Vim and python-2*. It should be easy to modify
+:file:`powerline/bindings/vim/autoload/powerline/debug.vim` to suit other
+needs.
