+
+`distro` provides information about the
+OS distribution it runs on, such as a reliable machine-readable ID, or
+version information.
+
+It is the recommended replacement for Python's original
+[`platform.linux_distribution`](https://docs.python.org/3.7/library/platform.html#platform.linux_distribution)
+function (which will be removed in Python 3.8).
+It also provides much more functionality which isn't necessarily Python bound,
+like a command-line interface.
+
+Distro currently supports Linux and BSD based systems but [Windows and OS X support](https://github.com/nir0s/distro/issues/177) is also planned.
+
+For Python 2.6 support, see https://github.com/nir0s/distro/tree/python2.6-support
+
+## Installation
+
+Installation of the latest released version from PyPI:
+
+```shell
+pip install distro
+```
+
+Installation of the latest development version:
+
+```shell
+pip install https://github.com/nir0s/distro/archive/master.tar.gz
+```
+
+
+## Usage
+
+```bash
+$ distro
+Name: Antergos Linux
+Version: 2015.10 (ISO-Rolling)
+Codename: ISO-Rolling
+
+$ distro -j
+{
+ "codename": "ISO-Rolling",
+ "id": "antergos",
+ "like": "arch",
+ "version": "16.9",
+ "version_parts": {
+ "build_number": "",
+ "major": "16",
+ "minor": "9"
+ }
+}
+
+
+$ python
+>>> import distro
+>>> distro.linux_distribution(full_distribution_name=False)
+('centos', '7.1.1503', 'Core')
+```
+
+
+## Documentation
+
+On top of the aforementioned API, several more functions are available. For a complete description of the
+API, see the [latest API documentation](http://distro.readthedocs.org/en/latest/).
+
+## Background
+
+An alternative implementation became necessary because Python 3.5 deprecated
+this function, and Python 3.8 will remove it altogether.
+Its predecessor function `platform.dist` was already deprecated since
+Python 2.6 and will also be removed in Python 3.8.
+Still, there are many cases in which access to that information is needed.
+See [Python issue 1322](https://bugs.python.org/issue1322) for more
+information.
+
+The `distro` package implements a robust and inclusive way of retrieving the
+information about a distribution based on new standards and old methods,
+namely from these data sources (from high to low precedence):
+
+* The os-release file `/etc/os-release`, if present.
+* The output of the `lsb_release` command, if available.
+* The distro release file (`/etc/*(-|_)(release|version)`), if present.
+* The `uname` command for BSD based distrubtions.
+
+
+## Python and Distribution Support
+
+`distro` is supported and tested on Python 2.7, 3.4+ and PyPy and on
+any distribution that provides one or more of the data sources
+covered.
+
+This package is tested with test data that mimics the exact behavior of the data sources of [a number of Linux distributions](https://github.com/nir0s/distro/tree/master/tests/resources/distros).
+
+
+## Testing
+
+```shell
+git clone git@github.com:nir0s/distro.git
+cd distro
+pip install tox
+tox
+```
+
+
+## Contributions
+
+Pull requests are always welcome to deal with specific distributions or just
+for general merriment.
+
+See [CONTRIBUTIONS](https://github.com/nir0s/distro/blob/master/CONTRIBUTING.md) for contribution info.
+
+Reference implementations for supporting additional distributions and file
+formats can be found here:

+
+ * the value of the "Distributor ID" attribute returned by the lsb_release

+ * the first part of the file name of the distro release file,
+
+ The so determined ID value then passes the following transformations,
+ before it is returned by this method:
+
+ * it is translated to lower case,
+
+ * blanks (which should not be there anyway) are translated to underscores,
+
+ * a normalization of the ID is performed, based upon
+ `normalization tables`_. The purpose of this normalization is to ensure
+ that the ID is as reliable as possible, even across incompatible changes
+ in the OS distributions. A common reason for an incompatible change is
+ the addition of an os-release file, or the addition of the lsb_release
+ command, with ID values that differ from what was previously determined
