+<h1>sview : tiny PHP web framework</h1>
+
+<h2>0. Installation</h2>
+
+<p>
+ In the following, I assume your website is located under http\[s\]://domain/topic/
+ and is named "website" (adapt to your case). For example, in https://github.com/blog/
+ domain = github.com and topic = blog.
+</p>
+
+<p>
+Get the source code either with <code>git clone</code> command or using a zip archive.
+ Copy all folder contents in the website/ folder :
+</p>
+<pre>website/
+ a/
+ f/
+ site/
+ .htaccess
+ common.php
+ defaults.php
+ index.php
+ s.php</pre>
+<ul>
+ <li><b>a/</b> (for "assets") is the folder for CSS files, images and javascript codes.
+ I like to put them respectively in css/, img/ and js/ folders, but the choice is yours.</li>
+ <li><b>f/</b> (for "files") is the folder for any downloadable (or browsable) file you may upload.</li>
+ <li><b>site/</b> is the main folder containing all your website pages. Three are already there :
+ <ul>
+ <li><i>404.php</i> : the 404 error page;</li>
+ <li><i>dl.php</i> : a script to download binary files;</li>
+ <li><i>home.php</i> : the specifications for the welcome page.</li>
+ </ul></li>
+ <li><b>.htaccess</b> : its main job consists in routing everything that is not a resource
+ to the index.php file.</li>
+ <li><b>common.php</b> contains shared variables and functions to be used by at least two different pages.</li>
+ <li><b>defaults.php</b> defines default variables for any web page, like the title or javascripts block.</li>
+ <li><b>index.php</b> contains your website template, which is rendered for any web page
+ (and filled with specific values defined in pages under site/ folder; anything can be customized).</li>
+ <li><b>s.php</b> consists in the framework code, loaded at the beginning of index.php.</li>
+</ul>
+
+<p>
+ Now (online), in the .htaccess file, change the line <code>RewriteBase /</code> to <code>RewriteBase /topic</code>.
+</p>
+
+<h2>1. Set default contents</h2>
+
+<span>Edit the file defaults.php with</span>
+<ul>
+ <li>A global title to your website; this title can later be mixed with a more specific
+ page-based title, or be replaced.</li>
+ <li>A list of references to CSS style sheets and pre-rendering javascript, like
+ <code><link rel="stylesheet" href="http://cran.r-project.org/R.css"/></code>.
+ We will see later how to refer to local style sheets (under a/css).</li>
+ <li>Some javascript code which will be loaded by default after every page loads
+ (e.g. <a href="http://jquery.com/">jquery</a>).</li>
+</ul>
+
+<p>
+ Each variable name is prepended with "b_" to avoid potential conflicts with your own variables.
+</p>
+
+<h2>2. Complete main pages</h2>
+
+<h3>index.php</h3>
+
+<span>Complete</span>
+<ul>
+ <li>The menu (at commented location)</li>
+ <li>The banner (near the menu, if you want one)</li>
+ <li>The footer (if you don't want one, just drop it).</li>
+</ul>
+
+<p>
+ You can also change the <meta> tags if needed.
+</p>
+
+<h3>site/home.php</h3>
+
+<p>
+ The welcome page. You can choose a title ($s_title) or use the default one
+ (by not specifying anything). Style sheets and javascripts can be customized, ...etc.
+ Any default variable can be used to define a specific variable (prepended with "s_").
+</p>
+
+<h3>site/404.php</h3>
+
+<p>
+ Customize it; it is probably viewed more often than you think ;-)
+</p>
+
+<h2>3. Write all other pages</h2>
+
+<p>
+ All pages are under site/ folder, and you can nest them in any directory tree.
+</p>
+
+<p>
+ <b>Hint</b> : if you don't want to load the main template, just end any site file
+ with a PHP <code>exit</code> directive.
+</p>
+
+<p>
+ Now we will see how to access pages and resources (images, CSS, files, javascript).
+</p>
+
+<hr/>
+
+<h2>How to view a web page ?</h2>
+
+<p>
+ The page at physical location site/some_folder/mypage.php is viewed in the web browser at the URL
+ http\[s\]://domain/topic/website/some_folder/mypage (thanks to URL rewriting defined in
+ the .htaccess file).
+</p>
+
+<p>
+ Any page can be linked internally using the <code>r()</code> PHP function ('r' for "resource"), like in
+ the following : <code><a href="<?php echo r('some_folder/mypage'); ?>"></code>. This function determines
+ the nesting level and output the appropriate path.
+</p>
+
+<h2>How to access...</h2>
+
+<p>
+ <i>A CSS style sheet</i> : its path is given by the following PHP function call
+ <code>r('a/css/name_of_the_file.css')</code> from within any site file (assuming you place all CSS files
+ under a/css/. They may be inside a nested folder structure).
+</p>
+
+<p>
+ <i>An image</i> : same as above, with <code>r('a/img/name_of_the_image.xxx')</code>.
+</p>
+
+<p>
+ <i>A javascript file</i> : same as above, with <code>r('a/js/name_of_the_file.js')</code>.
+</p>
+
+<h2>How to give a download link ?</h2>
+
+<p>
+ Just use a regular link pointing to <code>r('dl/?f=name_of_the_file.xxx')</code>, anywhere you want.
+</p>
+
+<hr/>
+
+<h2>Usual workflow</h2>
+
+<p>
+ Just add pages under site/ folder, and potential resources and files under a/ and f/.
+ All other files will not change a lot.
