+# HowTo: Create Themes
+*Note:* You should read the [Module Reference](Modules.md) and the [Template Reference](Templates.md) before.
+
+We assume you want to call your new theme _mytheme_. Make sure you replace this by your module name every time this is mentionend in this Howto.
+
+
+
+# Creating the structure
+At first create a new theme directory *themes/_mytheme_*.
+
+Create a _Makefile_ inside your theme directory with the following content:
+	
+	include ../../build/config.mk
+	include ../../build/module.mk
+	
+
+Create the following directory structure inside your theme directory.
+* ipkg
+* htdocs
+  * luci-static
+   * _mytheme_
+* luasrc
+  * view
+   * themes
+    * _mytheme_
+* root
+  * etc
+   * uci-defaults
+
+
+
+# Designing
+Create two LuCI HTML-Templates named _header.htm'' and ''footer.htm'' under *luasrc/view/themes/''mytheme_*.
+The _header.htm'' will be included at the beginning of each rendered page and the ''footer.htm_ at the end.
+So your _header.htm'' will probably contain a DOCTYPE description, headers, the menu and layout of the page and the ''footer.htm_ will close all remaining open tags and may add a footer bar but hey that's your choice you are the designer ;-).
+
+Just make sure your _header.htm_ *begins* with the following lines:
+	
+	<%
+	require("luci.http").prepare_content("text/html")
+	-%>
+	
+
+This makes sure your content will be sent to the client with the right content type. Of course you can adapt _text/html_ to your needs.
+
+
+Put any stylesheets, Javascripts, images, ... into *htdocs/luci-static/_mytheme_*.
+You should refer to this directory in your header and footer templates as: _<%=media%>''. That means for a stylesheet *htdocs/luci-static/''mytheme_/cascade.css* you would write:
+	
+	<link rel="stylesheet" type="text/css" href="<%=media%>/cascade.css" />
+	
+
+
+
+# Making the theme selectable
+If you are done with your work there are two last steps to do.
+To make your theme OpenWRT-capable and selectable on the settings page you should now create a file *root/etc/uci-defaults/luci-theme-_mytheme_* with the following contents:
+	
+	#!/bin/sh
+	uci batch <<-EOF
+	        set luci.themes.MyTheme=/luci-static/mytheme
+	        commit luci
+	EOF
+	
+
+and another file *ipkg/postinst* with the following content:
+	
+	#!/bin/sh
+	[ -n "${IPKG_INSTROOT}" ] || {
+	        ( . /etc/uci-defaults/luci-theme-mytheme ) &&        rm -f /etc/uci-defaults/luci-theme-mytheme
+	}
+	
+
+This is some OpenWRT magic to correctly register the template with LuCI when it gets installed.
+
+That's all. Now send your theme to the LuCI developers to get it into the development repository - if you like.
