+## Adding support for a new platform
+
+**IMPORTANT**: Before attempting to add support for a new platform please open
+an issue about it for discussion.
+
+### Unix
+
+I/O handling is abstracted by an internal `uv__io_t` handle. The new platform
+will need to implement some of the functions, the prototypes are in
+``src/unix/internal.h``.
+
+If the new platform requires extra fields for any handle structure, create a
+new include file in ``include/`` with the name ``uv-theplatform.h`` and add
+the appropriate defines there.
+
+All functionality related to the new platform must be implemented in its own
+file inside ``src/unix/`` unless it's already done in a common file, in which
+case adding an `ifdef` is fine.
+
+Two build systems are supported: autotools and GYP. Ideally both need to be
+supported, but if GYP does not support the new platform it can be left out.
+
+### Windows
+
+Windows is treated as a single platform, so adding support for a new platform
+would mean adding support for a new version.
+
+Compilation and runtime must succeed for the minimum supported version. If a
+new API is to be used, it must be done optionally, only in supported versions.
+
+### Common
+
+Some common notes when adding support for new platforms:
+
+* Generally libuv tries to avoid compile time checks. Do not add any to the
+  autotools based build system or use version checking macros.
+  Dynamically load functions and symbols if they are not supported by the
+  minimum supported version.

-Design overview
-===============
-
-libuv is cross-platform support library which was originally written for NodeJS. It's designed
-around the event-driven asynchronous I/O model.
-
-The library provides much more than simply abstraction over different I/O polling mechanisms:
-'handles' and 'streams' provide a high level abstraction for sockets and other entities;
-cross-platform file I/O and threading functionality is also provided, amongst other things.
-
-Here is a diagram illustrating the different parts that compose libuv and what subsystem they
-relate to:
-
-.. image:: static/architecture.png
-    :scale: 75%
-    :align: center
-
-
-Handles and requests
-^^^^^^^^^^^^^^^^^^^^
-
-libuv provides users with 2 abstractions to work with, in combination with the event loop:
-handles and requests.
-
-Handles represent long-lived objects capable of performing certain operations while active. Some
-examples: a prepare handle gets its callback called once every loop iteration when active, and
-a TCP server handle get its connection callback called every time there is a new connection.
-
-Requests represent (typically) short-lived operations. These operations can be performed over a
-handle: write requests are used to write data on a handle; or standalone: getaddrinfo requests
-don't need a handle they run directly on the loop.
-
-
-The I/O loop
-^^^^^^^^^^^^
-
-The I/O (or event) loop is the central part of libuv. It establishes the content for all I/O
-operations, and it's meant to be tied to a single thread. One can run multiple event loops
-as long as each runs in a different thread. The libuv event loop (or any other API involving
-the loop or handles, for that matter) **is not thread-safe** except where stated otherwise.
-
-The event loop follows the rather usual single threaded asynchronous I/O approach: all (network)
-I/O is performed on non-blocking sockets which are polled using the best mechanism available
-on the given platform: epoll on Linux, kqueue on OSX and other BSDs, event ports on SunOS and IOCP
-on Windows. As part of a loop iteration the loop will block waiting for I/O activity on sockets
-which have been added to the poller and callbacks will be fired indicating socket conditions
-(readable, writable hangup) so handles can read, write or perform the desired I/O operation.
-
-In order to better understand how the event loop operates, the following diagram illustrates all
-stages of a loop iteration:
-
-.. image:: static/loop_iteration.png
-    :scale: 75%
-    :align: center
-
-
-#. The loop concept of 'now' is updated. The event loop caches the current time at the start of
-   the event loop tick in order to reduce the number of time-related system calls.
-
-#. If the loop is *alive*  an iteration is started, otherwise the loop will exit immediately. So,
-   when is a loop considered to be *alive*? If a loop has active and ref'd handles, active
-   requests or closing handles it's considered to be *alive*.
-
-#. Due timers are run. All active timers scheduled for a time before the loop's concept of *now*
-   get their callbacks called.
-
-#. Pending callbacks are called. All I/O callbacks are called right after polling for I/O, for the
-   most part. There are cases, however, in which calling such a callback is deferred for the next
-   loop iteration. If the previous iteration deferred any I/O callback it will be run at this point.
-
-#. Idle handle callbacks are called. Despite the unfortunate name, idle handles are run on every
-   loop iteration, if they are active.
-
-#. Prepare handle callbacks are called. Prepare handles get their callbacks called right before
-   the loop will block for I/O.
-
-#. Poll timeout is calculated. Before blocking for I/O the loop calculates for how long it should
-   block. These are the rules when calculating the timeout:
-
-        * If the loop was run with the ``UV_RUN_NOWAIT`` flag, the timeout is 0.
-        * If the loop is going to be stopped (:c:func:`uv_stop` was called), the timeout is 0.
-        * If there are no active handles or requests, the timeout is 0.
-        * If there are any idle handles active, the timeout is 0.
-        * If there are any handles pending to be closed, the timeout is 0.
-        * If none of the above cases was matched, the timeout of the closest timer is taken, or
-          if there are no active timers, infinity.
-
-#. The loop blocks for I/O. At this point the loop will block for I/O for the timeout calculated
-   on the previous step. All I/O related handles that were monitoring a given file descriptor
-   for a read or write operation get their callbacks called at this point.
-
-#. Check handle callbacks are called. Check handles get their callbacks called right after the
-   loop has blocked for I/O. Check handles are essentially the counterpart of prepare handles.
-
-#. Close callbacks are called. If a handle was closed by calling :c:func:`uv_close` it will
-   get the close callback called.
-
-#. Special case in case the loop was run with ``UV_RUN_ONCE``, as it implies forward progress.
-   It's possible that no I/O callbacks were fired after blocking for I/O, but some time has passed
-   so there might be timers which are due, those timers get their callbacks called.
-
-#. Iteration ends. If the loop was run with ``UV_RUN_NOWAIT`` or ``UV_RUN_ONCE`` modes the
-   iteration is ended and :c:func:`uv_run` will return. If the loop was run with ``UV_RUN_DEFAULT``
-   it will continue from the start if it's still *alive*, otherwise it will also end.
-
-
-.. important::
-    libuv uses a thread pool to make asynchronous file I/O operations possible, but
-    network I/O is **always** performed in a single thread, each loop's thread.
-
-.. note::
-    While the polling mechanism is different, libuv makes the execution model consistent
-    across Unix systems and Windows.
-
-
-File I/O
-^^^^^^^^
-
-Unlike network I/O, there are no platform-specific file I/O primitives libuv could rely on,
-so the current approach is to run blocking file I/O operations in a thread pool.
-
-For a thorough explanation of the cross-platform file I/O landscape, checkout
-`this post <http://blog.libtorrent.org/2012/10/asynchronous-disk-io/>`_.
-
-libuv currently uses a global thread pool on which all loops can queue work on. 3 types of
-operations are currently run on this pool:
-
-    * Filesystem operations
-    * DNS functions (getaddrinfo and getnameinfo)
-    * User specified code via :c:func:`uv_queue_work`
-
-.. warning::
-    See the :c:ref:`threadpool` section for more details, but keep in mind the thread pool size
-    is quite limited.

-=========================================
-
-FS Poll handles allow the user to monitor a given path for changes. Unlike

-
-    Callback passed to :c:func:`uv_fs_poll_start` which will be called repeatedly
-    after the handle is started, when any change happens to the monitored path.
-
-    The callback is invoked with `status < 0` if `path` does not exist
-    or is inaccessible. The watcher is *not* stopped but your callback is
-    not called again until something changes (e.g. when the file is created
-    or the error reason changes).
-
-    When `status == 0`, the callback receives pointers to the old and new
