+_Server and client system requirements for TWiki 01-Sep-2001_
+
+## <a name="Overview"> Overview </a>
+
+Maintaining minimum client and server requirements is necessary to keep TWiki deployment as broad as possible.

+
+TWiki is written in Perl 5, uses a number of shell commands, and requires [RCS (Revision Control System)](http://www.gnu.org/software/rcs/rcs.html), a GNU Free Software package. TWiki is developed in a basic Linux/Apache environment. It also works with Microsoft Windows, and should have no problem on any other platform that meets the requirements:

+Current documentation covers Linux only. A [TWikiOnWindows](http://twiki.org/cgi-bin/view/Codev/TWikiOnWindows) installation guide is next.
+
+## <a name="Client_Requirements"> Client Requirements </a>
+
+The TWiki [[TWikiInstallationGuide]] has extremely low browser requirements:
+
+* HTML 3.2 compliant
+* generates XHTML 1.0 pages that are compatible with HTML 3.2
+* minimal use of JavaScript in the user interface (degrades gracefully)
+* no cookies
+* no CSS
+
+You can easily add capabilities, through customizing the templates, for one, while tailoring the browser requirements to your situation.
+
+## <a name="Known_Issues"> Known Issues </a>
+
+* The new [[TWikiPlugins]] feature currently does not have compatibility guidelines for developers. Plugins can require just about anything: browser-specific functions, stylesheets (CSS), DHTML, Java applets, cookies.
