+
+Generic requirements
+====================
+
+* Python 2.6 or later, 3.2 or later, PyPy 2.0 or later, PyPy3 2.3 or later. It 
+  is the only non-optional requirement.
+
+  .. warning:
+     It is highly advised to use UCS-4 version of Python because UCS-2 version 
+     uses significantly slower text processing (length determination and 
+     non-printable character replacement) functions due to the need of 
+     supporting unicode characters above U+FFFF which are represented as 
+     surrogate pairs. This price will be paid even if configuration has no such 
+     characters.
+
+* C compiler. Required to build powerline client on linux. If it is not present 
+  then powerline will fall back to shell script or python client.
+* ``socat`` program. Required for shell variant of client which runs a bit 
+  faster than python version of the client, but still slower than C version.
+* ``psutil`` python package. Required for some segments like cpu_percent. Some 
+  segments have linux-only fallbacks for ``psutil`` functionality.
+* ``hglib`` python package *and* mercurial executable. Required to work with
+  mercurial repositories.
+* ``pygit2`` python package or ``git`` executable. Required to work with ``git`` 
+  repositories.
+* ``bzr`` python package (note: *not* standalone executable). Required to work 
+  with bazaar repositories.
+* ``pyuv`` python package. Required for :ref:`libuv-based watcher 
+  <config-common-watcher>` to work.
+* ``i3ipc`` python package. Required for i3wm bindings and segments.
+* ``xrandr`` program. Required for the multi-monitor lemonbar binding and the 
+  :py:func:`powerline.listers.i3wm.output_lister`.
+
+.. note::
+    Until bazaar supports Python-3 or PyPy powerline will not support
+    repository information when running in these interpreters.
+
+.. _repository-root:
+
+.. note::
+   When using ``pip``, the ``{repository_root}`` directory referenced in 
+   documentation may be found using ``pip show powerline-status``. In the output 
+   of ``pip show`` there is a line like ``Location: {path}``, that ``{path}`` is 
+   ``{repository_root}``. Unless it is ``--editable`` installation this is only 
+   applicable for ``{repository_root}/powerline/…`` paths: something like 
+   ``{repository_root}/scripts/powerline-render`` is not present.
+
+   When using other packages referenced paths may not exist, in this case refer 
+   to package documentation.
+
+Pip installation
+================
+
+Due to a naming conflict with an unrelated project powerline is available on 
+PyPI under the ``powerline-status`` name:
+
+.. code-block:: sh
+
+    pip install powerline-status
+
+is the preferred method because this will get the latest release. To get current 
+development version
+
+.. code-block:: sh
+
+    pip install --user git+git://github.com/powerline/powerline
+
+may be used. If powerline was already checked out into some directory
+
+.. code-block:: sh
+
+    pip install --user --editable={path_to_powerline}
+
+is useful, but note that in this case ``pip`` will not install ``powerline`` 
+executable and something like
+
+.. code-block:: sh
+
+    ln -s {path_to_powerline}/scripts/powerline ~/.local/bin
+
+will have to be done (:file:`~/.local/bin` should be replaced with some path 
+present in ``$PATH``).
+
+.. note::
+    If ISP blocks git protocol for some reason github also provides ``ssh`` 
+    (``git+ssh://git@github.com/powerline/powerline``) and ``https`` 
+    (``git+https://github.com/powerline/powerline``) protocols. ``git`` protocol 
+    should be the fastest, but least secure one though.
+
+Fonts installation
+==================
+
+Powerline uses several special glyphs to get the arrow effect and some custom 
+symbols for developers. This requires having either a symbol font or a patched 
+font installed in the system. The used application (e.g. terminal emulator) must 
+also either be configured to use patched fonts (in some cases even support it 
+because custom glyphs live in private use area which some applications reserve 
+for themselves) or support fontconfig for powerline to work properly with 
+powerline-specific glyphs.
+
+:ref:`24-bit color support <config-common-term_truecolor>` may be enabled if 
+used terminal emulator supports it (see :ref:`the terminal emulator support 
+matrix <usage-terminal-emulators>`).
+
+There are basically two ways to get powerline glyphs displayed: use 
+:file:`PowerlineSymbols.otf` font as a fallback for one of the existing fonts or 
+install a patched font.
+
+.. _installation-patched-fonts:
+
+Patched fonts
+-------------
+
+This method is the fallback method and works for every terminal.
+
+Download the font from `powerline-fonts`_. If preferred font can’t be found in 
+the `powerline-fonts`_ repo, then patching the preferred font is needed instead.
+
+.. _powerline-fonts: https://github.com/powerline/fonts
+
+After downloading this font refer to platform-specific instructions.
