 The MicroPython project
 =======================

 "make" is used to build the components, or "gmake" on BSD-based systems.
 You will also need bash and Python (at least 2.7 or 3.3).
 
-The Unix version
-----------------
-
-The "unix" port requires a standard Unix environment with gcc and GNU make.
-x86 and x64 architectures are supported (i.e. x86 32- and 64-bit), as well
-as ARM and MIPS. Making full-featured port to another architecture requires
-writing some assembly code for the exception handling and garbage collection.
-Alternatively, fallback implementation based on setjmp/longjmp can be used.
-
-To build (see section below for required dependencies):
-
-    $ cd unix
-    $ make axtls
-    $ make
-
-Then to give it a try:
-
-    $ ./micropython
-    >>> list(5 * x + y for x in range(10) for y in [4, 2, 1])
-
-Use `CTRL-D` (i.e. EOF) to exit the shell.
-Learn about command-line options (in particular, how to increase heap size
-which may be needed for larger applications):
-
-    $ ./micropython --help
-
-Run complete testsuite:
-
-    $ make test
-
-Unix version comes with a builtin package manager called upip, e.g.:
-
-    $ ./micropython -m upip install micropython-pystone
-    $ ./micropython -m pystone
-
-Browse available modules on
-[PyPI](https://pypi.python.org/pypi?%3Aaction=search&term=micropython).
-Standard library modules come from
-[micropython-lib](https://github.com/micropython/micropython-lib) project.
-
-External dependencies
----------------------
-
-Building Unix version requires some dependencies installed. For
-Debian/Ubuntu/Mint derivative Linux distros, install `build-essential`
-(includes toolchain and make), `libffi-dev`, and `pkg-config` packages.
-
-Other dependencies can be built together with MicroPython. Oftentimes,
-you need to do this to enable extra features or capabilities. To build
-these additional dependencies, first fetch git submodules for them:
-
-    $ git submodule update --init
-
-Use this same command to get the latest versions of dependencies, as
-they are updated from time to time. After that, in `unix/` dir, execute:
-
-    $ make deplibs
-
-This will build all available dependencies (regardless whether they
-are used or not). If you intend to build MicroPython with additional
-options (like cross-compiling), the same set of options should be passed
-to `make deplibs`. To actually enabled use of dependencies, edit
-`unix/mpconfigport.mk` file, which has inline descriptions of the options.
-For example, to build SSL module (required for `upip` tool described above),
-set `MICROPY_PY_USSL` to 1.
-
-In `unix/mpconfigport.mk`, you can also disable some dependencies enabled
-by default, like FFI support, which requires libffi development files to
-be installed.
