 dwm \- dynamic window manager
 .SH SYNOPSIS
 .B dwm
 .RB [ \-v ]
 .SH DESCRIPTION
-dwm is a dynamic window manager for X. It manages windows in tiled, monocle
+.SS Overview
-and floating layouts. Either layout can be applied dynamically, optimising the
+.B dwm
-environment for the application in use and the task performed.
+is a dynamic window manager for X11.
-.P
+.SS Options
-In tiled layouts windows are managed in a master and stacking area. The master
-area on the left contains one window by default, and the stacking area on the
-right contains all other windows. The number of master area windows can be
-adjusted from zero to an arbitrary number. In monocle layout all windows are
-maximised to the screen size. In floating layout windows can be resized and
-moved freely. Dialog windows are always managed floating, regardless of the
-layout applied.
-.P
-Windows are grouped by tags. Each window can be tagged with one or multiple
-tags. Selecting certain tags displays all windows with these tags.
-.P
-Each screen contains a small status bar which displays all available tags, the
-layout, the title of the focused window, and the text read from the root window
-name property, if the screen is focused. A floating window is indicated with an
-empty square and a maximised floating window is indicated with a filled square
-before the windows title.  The selected tags are indicated with a different
-color. The tags of the focused window are indicated with a filled square in the
-top left corner.  The tags which are applied to one or more windows are
-indicated with an empty square in the top left corner.
-.P
-dwm draws a small border around windows to indicate the focus state.

-.SH CUSTOMIZATION
-dwm is customized by creating a custom config.h and (re)compiling the source
-code. This keeps it fast, secure and simple.
-.SH SEE ALSO
-.BR dmenu (1),
-.BR st (1)
-.SH ISSUES
-Java applications which use the XToolkit/XAWT backend may draw grey windows
-only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early
-JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds
-are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the
-environment variable
-.BR AWT_TOOLKIT=MToolkit
-(to use the older Motif backend instead) or running
-.B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D
-or
-.B wmname LG3D
-(to pretend that a non-reparenting window manager is running that the
-XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable
-.BR _JAVA_AWT_WM_NONREPARENTING=1 .
-.SH BUGS
-Send all bug reports with a patch to hackers@suckless.org.

+			<h3>dynamic window manager</h3>
+		</center>
+		<h3>Description</h3>
+		<p>
+		dwm is a dynamic window manager for X11.
+		</p>
+		<h3>Philosophy</h3>
+		<p>
+		As founder and main developer of wmii I came to the conclusion that
+		wmii is too clunky for my needs. I don't need so many funky features
+		and all this hype about remote control through a 9P service, I only
+		want to manage my windows in a simple, but dynamic way. wmii never got
+		finished because I listened to users, who proposed arbitrary ideas I
+		considered useful. This resulted in an extreme <a href="http://www.jwz.org/doc/cadt.html">CADT</a>
+		development model, which was a mistake. Thus the philosophy of
+		dwm is simply <i>to fit my needs</i> (maybe yours as well). That's it.
+		</p>
+		<h3>Differences to wmii</h3	
+		<p>
+		In contrast to wmii, dwm is only a window manager, and nothing else.
+		Hence, it is much smaller, faster and simpler.
+		</p>
+		<ul>
+			<li>
+			dwm has no 9P support, no menu, no editable tagbars,
+			no shell-based configuration and remote control and comes without
+			any additional tools like printing the selection or warping the
+			mouse.
+			</li>
+			<li>
+			dwm is only a single binary, it's source code is intended to never
+			exceed 2000 SLOC.
+			</li>
+			<li>
+			dwm is customized through editing its source code, that makes it
+			extremely fast and secure - it does not process any input data which
+			hasn't been known at compile time, except window title names.
+			</li>
+			<li>
+			dwm is based on tagging and dynamic window management (however simpler
+			than wmii or larswm).
+			</li>
+			<li>
+			dwm don't distinguishes between layers, there is no floating or
+			managed layer. Wether the clients of currently selected tag are
+			managed or not, you can re-arrange all clients on the fly. Popup-
+			and fixed-size windows are treated unmanaged. 
+			</li>
+			<li>
+			dwm uses 1-pixel borders to provide the maximum of screen real
+			estate to clients. Small titlebars are only drawn in front of unfocused
+			clients.
+			</li>
+			<li>
+			dwm reads from <b>stdin</b> to print arbitrary status text (like the
+			date, load, battery charge). That's much simpler than larsremote,
+			wmiir and what not...
+			</li>
+			<li>
+			garbeam <b>does not</b> want any feedback to dwm. If you ask for support,
+			feature requests, or if you report bugs, they will be <b>ignored</b>
+			with a high chance. dwm is only intended to fit garbeams needs.
+			However you are free to download and distribute/relicense it, with the
+			conditions of the <a href="http://wmii.de/cgi-bin/hgwebdir.cgi/dwm?f=f10eb1139362;file=LICENSE;style=raw">MIT/X Consortium license</a>.
+			</li>

+		</p>
+		<h3>Development</h3>
+		<p>
+		dwm is actively developed in parallel to wmii. You can <a href="http://wmii.de/cgi-bin/hgwebdir.cgi/dwm">browse</a> its source code repository or get a copy using <a href="http://www.selenic.com/mercurial/">Mercurial</a> with following command:
+		</p>
+		<p>
+		<code>hg clone http://wmii.de/cgi-bin/hgwebdir.cgi/dwm</code>
+		</p>
+		<h3>Download</h3>
+		<ul>
+			<li><a href="http://wmii.de/download/dwm-0.1.tar.gz">dwm 0.1</a> (12kb) (20060714)</li>
+		</ul>
+		<h3>Miscellaneous</h3>
+		<p>
+		You can purchase this <a href="https://www.spreadshirt.net/shop.php?op=article&article_id=3298632&view=403">tricot</a>
+		if you like dwm and the dwm logo, which has been designed by garbeam.
