  * Sources for Tahoe-LAFS and its side-projects are browsable via the "Browse Source" button at the top of each [project site](http://allmydata.org/trac)
  * To fetch the source code using [darcs v2](http://darcs.net): `darcs get --lazy <http://allmydata.org/source/tahoe-lafs/trunk> tahoe-lafs`
   * `darcs v2` is highly recommended over `darcs v1`.  If you really don't want to install `darcs v2`, then you can use `darcs v1` instead, but you'll have to run a slightly different command-line and be prepared to wait for tens of minutes for the initial `get` to finish.  The command-line for `darcs v1` is: `darcs get <http://allmydata.org/source/tahoe/trunk-darcs1format> tahoe`.
+ * there is an experimental git mirror of the darcs repository (not necessarily up-to-date) [on github](http://github.com/warner/tahoe-lafs).
  * <http://allmydata.org/source/tahoe/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](BuildbotPolicy) page and [HowtoContributeABuildbot](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).
