-1. CONFIGURE YOUR WEBSERVER TO WORK WITH PHP4
----------------------------------------------
-
-  If your webserver does not already have PHP4 you must configure it
-  to work with PHP4. SquirrelMail uses the standard suffix .php for
-  all PHP4 files. This is a quick and dirty guide to installing PHP4
-  to run as CGI under Apache. How you end up doing this is up to you
-  (your mileage may vary).
-
-  You will need at least PHP v4.1.0. If you need to upgrade please go
-  ahead and install it now.
-
-a. Obtaining and compiling PHP4
-  
-  SquirrelMail has not been extensively tested for use with PHP 4.3.x.
-  See the ReleaseNotes file.
-
-  Point your favorite web browser at http://www.php.net/downloads.php/ and
-  download the source. Untar (tar xvfz filename-you-downloaded.tgz)
-  the source, cd into the directory and run configure. To make PHP4
-  work with SquirrelMail a commandline like this should do:
-
-   ./configure --enable-track-vars --enable-force-cgi-redirect --with-gettext
-
-  If you have a database like MySQL you might want to add something
-  like --with-mysql to get database functionality.
-
-  If you're going to use LDAP in the addressbook, you must compile PHP4
-  with --with-ldap (see the PHP4 docs for more information).
-
-  Run make to build the binary file. This will generate a binary file
-  called "php". Move this file into a CGI-directory.
+0. QUICK INSTALL GUIDE
+----------------------
 
-  You might also want to read the INSTALL file in the PHP-distribution
-  :-)
+Each of these steps is covered in detail below.
 
-b. Changing php.ini
-
-  PHP defaults to look for php.ini (PHP's configuration file) in
-  /usr/local/lib.  However, for security reasons, it is suggested
-  that the location of this file is changed to someplace else.  This
-  can be done at configure time with the configuration directive
-  --with-config-file-path=PATH.
-
-  Edit the php.ini file and make sure session.use_cookies is 1.  Also 
-  be sure to change the session.save_path to someplace that can only 
-  be read and written to by the webserver.  session.save_path is the
-  location that PHP's session data will be written to.
-
-  SECURITY WARNING - If a user has access to write PHP scripts on your 
-  system and knows the location where PHP stores session data, he 
-  could get a listing of the sessions being used and then read a given 
-  session's data with his own PHP script.  Caution should be used when 
-  setting up permissions and locations of php.ini and the session data.
+- Install webserver and PHP4 (at least 4.1.0).
+- Install IMAP server (see docs of that server).
+- Unpack the SquirrelMail package in a web-accessible location.
+- Select a data-dir and attachment dir, outside the webtree (e.g. in /var).
+  The data-dir (for user prefs) should be owned by the user the webserver
+  runs as (eg www-data). The attachment dir (for uploading files as
+  attachments) should be file mode 0730 and in the same group as the
+  webserver.
+- Run config/conf.pl from the command line. Use the D option to load
+  predefined options for specific IMAP servers, and edit at least the
+  Server Settings and General Options (datadir).
+- Browse to http://www.example.com/yourwebmaillocation/src/configtest.php
+  to test your configuration for common errors.
+- Browse to http://www.example.com/yourwebmaillocation/ to log in.
 
-  FILE UPLOADS - Note that sending attachments will not work if your
-  "file_uploads" setting is "Off". Squirrelmail requires that setting
-  enabled in order to be able to attach files.
 
-c. Setting up .php files to use PHP4
+1. CONFIGURE YOUR WEBSERVER TO WORK WITH PHP4
+---------------------------------------------
 
-  You need to create a .htaccess file in you SquirrelMail directory
-  that looks something like this:
+  If your webserver does not already have PHP you must configure it
+  to work with PHP. You need at least PHP v4.1.0. SquirrelMail uses
+  the standard suffix .php for all PHP4 files.
+  
+  You can find PHP at http://www.php.net. See the documentation that
+  comes with PHP for instructions how to set it up.
 
-    AddType application/php4script .php
-    Action application/php4script /cgi-bin/php
+  The PHP IMAP extension is NOT neccessary at all (but won't harm)!
+  Below is a list of optional PHP extensions:
 
-  You could also add these lines to your Apache configuration file.
+  --with-ldap     Required for LDAP addressbooks
+  --with-mhash    Will improve charset decoding if present
+  --with-mysql    For MySQL storage of preferences or addressbooks
+  --with-openssl  When you want to use encrypted IMAP connections (TLS)
+  
+  If you're going to use LDAP in the addressbook, you must compile PHP
+  with the LDAP extension. Include the MHASH extension to improve
+  performance in character set decoding.
 
-d. Running into trouble
+  If you want your users to attach files to their mails, make sure
+  File Uploads in php.ini is set to On.
 
-  Setting up Apache with PHP4 can be a non-trivial task. Read the PHP4
-  and Apache documentation carefully if you run into trouble. If you
-  have an experienced system administrator around ask her/him to help
-  you.
 
 2. SETTING UP IMAP
 ------------------
 
-  This is not covered here :-/
+  This depends a lot on the server your choose. See the documentation
+  that comes with your server.
+  
+  If you're concerned about people accessing it directly, you can
+  limit access to only the IP of the webserver.
+
 
 3. OBTAINING AND INSTALLING SQUIRRELMAIL
 ----------------------------------------
 
   SquirrelMail is constantly being improved. Therefore you should always
-  get the newest version around. Look at http://www.squirrelmail.org/
+  get the newest version around. Look at http://www.squirrelmail.org
   to see what it is. If you want to be bleeding edge you might want to
   consider using the latest CVS version (with the latest and most
