Tahoe-LAFS
==========

Tahoe-LAFS is a Free and Open decentralized cloud storage system. It
distributes your data across multiple servers. Even if some of the servers
fail or are taken over by an attacker, the entire file store continues to
function correctly, preserving your privacy and security.

INSTALLING
==========

There are three ways to install Tahoe-LAFS.

using OS packages
^^^^^^^^^^^^^^^^^

Pre-packaged versions are available for several operating systems:

* Debian and Ubuntu users can ``apt-get install tahoe-lafs``
* NixOS, NetBSD (pkgsrc), ArchLinux, Slackware, and Gentoo have packages
  available, see `OSPackages`_ for details
* `Mac`_ and Windows installers are in development.

via pip
^^^^^^^

If you don't use an OS package, you'll need Python 2.7 and `pip`_. You may
also need a C compiler, and the development headers for python, libffi, and
OpenSSL. On a Debian-like system, use ``apt-get install build-essential
python-dev libffi-dev libssl-dev python-virtualenv``. On Windows, see
`<docs/windows.rst>`_.

Then, to install the most recent release, just run:

* ``pip install tahoe-lafs``

from source
^^^^^^^^^^^
To install from source (either so you can hack on it, or just to run
pre-release code), you should create a virtualenv and install into that:

* ``git clone https://github.com/tahoe-lafs/tahoe-lafs.git``
* ``cd tahoe-lafs``
* ``virtualenv --python=python2.7 venv``
* ``venv/bin/pip install --upgrade setuptools``
* ``venv/bin/pip install --editable .``
* ``venv/bin/tahoe --version``

To run the unit test suite:

* ``tox``

You can pass arguments to ``trial`` with an environment variable.  For
example, you can run the test suite on multiple cores to speed it up:

* ``TAHOE_LAFS_TRIAL_ARGS="-j4" tox``

For more detailed instructions, read `<docs/INSTALL.rst>`_ .

Once ``tahoe --version`` works, see `<docs/running.rst>`_ to learn how to set
up your first Tahoe-LAFS node.
