Views into the process of Tahoe-LAFS hackery.
 * The Roadmap page (linked at the top of each page) shows the next planned release and what improvements and bugfixes we are working on.
 * [wiki:Doc The User Doc page]

== Source Code (via revision control) ==

 * Darcs checkout:
     {{{darcs get --lazy https://tahoe-lafs.org/source/tahoe-lafs/trunk tahoe-lafs}}}
 * [https://github.com/warner/tahoe-lafs git checkout] (EXPERIMENTAL!) announced [//pipermail/tahoe-dev/2010-October/005408.html here]:
     {{{git clone git://github.com/warner/tahoe-lafs.git}}}

== Community ==

 * [/../../cgi-bin/mailman/listinfo/tahoe-dev The tahoe-dev mailing list] is the community forum for discussion of Tahoe-LAFS design, implementation, and usage.
 * Tahoe-LAFS hackers chat on [irc://irc.freenode.net/%23tahoe-lafs irc.freenode.net in channel #tahoe-lafs]. This channel is archived at [http://fred.submusic.ch/irc/tahoe-lafs/] .
 * [source:CREDITS The CREDITS file] contains names people who have contributed to the Tahoe-LAFS project.
 * [wiki:RelatedProjects The RelatedProjects page] has extensions to Tahoe-LAFS and integrations of Tahoe-LAFS with other open source software.

== Extensions ==

 * Tahoe-LAFS has a programmatic API which enables building custom applications on top of the storage infrastructure.
 * The [source:docs/frontends/webapi.rst] document shows how to control a Tahoe-LAFS node programmatically over HTTP.
 * [wiki:Extensions The Extension Page] has some additional tips on how to use the web-API.

== Developer Docs ==

=== Design of the System ===
 * [http://code.google.com/p/nilestore/wiki/TahoeLAFSBasics TahoeLAFSBasics] on the Nilestore Project's site. This document was written by someone from another project who hasn't really interacted with the Tahoe-LAFS developers much, but it is the best overall introduction to the design of Tahoe-LAFS.
 * after that, look at the "Presentations / Papers", below, or at the "architecture.rst" file in the docs/ directory.

=== Presentations / Papers ===
 * [//trac/tahoe-lafs/attachment/wiki/News/tahoe-RSA-slides.pdf] presented at RSA 2010
 * [//~zooko/lafs.pdf Tahoe – The Least-Authority Filesystem] presented at [http://storagess.org/2008 Storage Security and Survivability '08]
 * [//~warner/pycon-tahoe.html Tahoe: A Secure Distributed Filesystem] presented at
   [http://us.pycon.org/2008/about/ PyCon2008],
   providing an overview of the Tahoe-LAFS design, and the
   [//~warner/pycon-tahoe-slides.zip slides] (.zip) that
   were used for the presentation
 * [http://www.cs.utk.edu/~plank/plank/papers/FAST-2009.html  A Performance Evaluation and Examination of Open-Source Erasure Coding Libraries For Storage] to be presented at [http://www.usenix.org/events/fast09  FAST-2009: 7th USENIX Conference on File and Storage Technologies]

=== More Details To Look Up While Working On Your Contribution ===
 * [source:docs/ the docs/ directory] <-- most core doc is in the source tree here
 * [wiki:Capabilities]: what are readcaps and writecaps and verifycaps, etc
 * [wiki:Packaging The Packaging page] shows our current policy for how to re-use 3rd-party libraries and how to distribute Tahoe-LAFS to users.

== Tools ==
 * [//cgi-bin/mailman/listinfo/tahoe-lafs-trac-stream tahoe-lafs-trac-stream] mailing list is the way to receive lots of emails from trac
 * Sources for Tahoe-LAFS and its side-projects are browsable via the "Browse Source" button at the top of each [//trac project site]
 * there is an experimental git mirror of the darcs repository (not necessarily up-to-date) [http://github.com/warner/tahoe-lafs on github].
 * [//source/tahoe-lafs/tarballs/ https://source/tahoe-lafs/tarballs] contains snapshots of current source code.
 * The Buildbot page (linked at the top of each page) shows current build and test results.  See the BuildbotPolicy page and [wiki:HowtoContributeABuildbot] page.
 * The Timeline (linked at the top of each page) shows changes to the source code, the issue tickets, and the wiki (i.e. this web site).
 * [/../../tahoe-figleaf/current The code coverage statistics] show which lines of code get exercised by the unit tests.
   * [/../../tahoe-figleaf Archived data] is also available.
   * [/../../tahoe-figleaf-graph/hanford.allmydata.com-tahoe_figleaf2.html This graph] measures the number of lines that are '''not''' covered.

== Dependencies ==

 * Copies of libraries that Tahoe-LAFS is dependent on are at [//source/tahoe-lafs/deps/].
 * The [//source/tahoe-lafs/deps/tahoe-dep-eggs tahoe-dep-eggs] subdirectory has precompiled "egg" packages (scroll to the bottom for a matrix of platforms and Python versions for each package).


== Metrics ==

 * [wiki:Performance The Performance page] has notes and graphs about performance measurements.
 * [wiki:TestGrid The TestGrid page] contains usage statistics about the public test grid.
