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

+# sview : tiny PHP web framework.
+
+It is inspired by [a similar framework](http://shortphp.com) written by Arnór Heiðar Sigurðsson. 
+In the same spirit but more advanced and more complete, see also [nanoc](http://nanoc.ws/) - in Ruby.
+
+sview is designed to organize essentially static websites. 
+It does not offer the features you would expect from a complete MVC framework - 
+actually, it has only the "V" part. 
+If you want a more demanding dynamic website, consider using an appropriate tool, 
+[Symfony](http://symfony.com/) for example.
+
+## How to use it ?
+
+The documentation is [right 
+here](http://git.redua.net/?p=sview.git;a=blob;f=HOWTO.md;hb=HEAD), 
+and a full website example is [located 
+here](http://git.redua.net/?p=sview.git;a=blob;f=sample-website.tar.xz;hb=HEAD).
