-### Why Use Mercurial

 * Distributed Architecture - Traditionally version control systems such as CVS
 and Subversion are a client server architecture with a central server to
 store the revsion history of a project. Mercurial however is a truly
 distributed architecture, giving each devloper a full local copy of the
 entire development history. It works independently of a central server.

 independently of a central server.
-
 * Platform Independent - Mercurial was written to be highly platform
 independent. Much of Mercurial is written in Python, with small performance
 critical parts written in portable C. Binary releases are available for all
 major platforms.
-
 * Extensible - The functionality of Mercurial can be increased with extensions,
 either by activating the official ones which are shipped with Mercurial or
-downloading some [from the
-wiki](https://www.mercurial-scm.org/wiki/UsingExtensions) or by [writing your
-own](https://www.mercurial-scm.org/wiki/WritingExtensions). Extensions are
-written in Python and can change the workings of the basic commands, add new
-commands and access all the core functions of Mercurial.

 * Easy to use - The Mercurial command set is consistent with what subversion
 users would expect, so they are likely to feel right at home. Most dangerous
 actions are part of extensions that need to be enabled to be used.
-
 * Open Source - Mercurial is free software licensed under the terms of the [GNU
 General Public License Version 2](http://www.gnu.org/licenses/gpl-2.0.txt) or
 any later version.
