 INSTALLATION
 ============
 
 1. Decompress and put this folder somewhere inside your document root
-2. Make sure that the following directories (and the files within)
+2. Install dependencies using composer:
+   - get composer from https://getcomposer.org/download/
+   - rename the composer.json-dist file into composer.json
+   - if you want to use LDAP address books, enable the LDAP libraries in your
+     composer.json file by moving the items from "suggest" to the "require"
+     section (remove the explanation texts after the version!).
+   - run `php composer.phar install --no-dev`
+3. Make sure that the following directories (and the files within)
    are writable by the webserver
    - /temp
    - /logs
-3. Create a new database and a database user for RoundCube (see DATABASE SETUP)
-4. Create database tables using the queries in file 'SQL/*.initial.sql'
-   (* stands for your database type)
-5. Rename the files config/*.inc.php.dist to config/*.inc.php
-6. Modify the files in config/* to suit your local environment
-7. Done!
+4. Create a new database and a database user for Roundcube (see DATABASE SETUP)
+5. Point your browser to http://url-to-roundcube/installer/
+6. Follow the instructions of the install script (or see MANUAL CONFIGURATION)
+7. After creating and testing the configuration, remove the installer directory
+8. Check Known Issues section of this file
+
+
+CONFIGURATION HINTS
+===================
+
+IMPORTANT! Read all comments in defaults.inc.php, understand them
+and configure your installation to be not surprised by default behaviour.
+
+Roundcube writes internal errors to the 'errors' log file located in the logs
+directory which can be configured in config/config.inc.php. If you want ordinary
+PHP errors to be logged there as well, enable the 'php_value error_log' line
+in the .htaccess file and set the path to the log file accordingly.
+
+By default the session_path settings of PHP are not modified by Roundcube.
+However if you want to limit the session cookies to the directory where
+Roundcube resides you can uncomment and configure the according line
+in the .htaccess file.
 
 
 DATABASE SETUP
 ==============
+
+Note: Database for Roundcube must use UTF-8 character set.
+Note: See defaults.inc.php file for examples of DSN configuration.
 
 * MySQL
 -------

 roundcube user. Here is an example of that procedure:
 
 # mysql
-> CREATE DATABASE 'roundcubemail';
+> CREATE DATABASE roundcubemail /*!40101 CHARACTER SET utf8 COLLATE utf8_general_ci */;
 > GRANT ALL PRIVILEGES ON roundcubemail.* TO roundcube@localhost
-        IDENTIFIED BY 'password';
+    IDENTIFIED BY 'password';
 > quit
+
 # mysql roundcubemail < SQL/mysql.initial.sql
 
-For MySQL version 4.1 and up, it's recommended to create the database for
-RoundCube with the following command:
-> CREATE DATABASE 'roundcubemail' DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
+Note 1: 'password' is the master password for the roundcube user. It is strongly
+recommended you replace this with a more secure password. Please keep in
+mind: You need to specify this password later in 'config/db.inc.php'.
 
 
 * SQLite
 --------
-Sqlite requires specifically php5 (sqlite in php4 currently doesn't
-work with roundcube), and you need sqlite 2 (preferably 2.8) to setup
-the sqlite db (sqlite 3.x also doesn't work at the moment). Here is
-an example how you can setup the sqlite.db for roundcube:
-
-# sqlite -init SQL/sqlite.initial.sql sqlite.db
-
-Make sure your configuration points to the sqlite.db file and that the
-webserver can write to the file.
+Versions of sqlite database engine older than 3 aren't supported.
+Database file and structure is created automatically by Roundcube.
+Make sure your configuration points to some file location and that the
+webserver can write to the file and the directory containing the file.
 
 
 * PostgreSQL
 ------------
-To use RoundCube with PostgreSQL support you have to follow the next
-simple steps, which have to be done with the postgres system user (or
+To use Roundcube with PostgreSQL support you have to follow these
+simple steps, which have to be done as the postgres system user (or
 which ever is the database superuser):
 
-$ createuser roundcubemail
-$ createdb -O roundcubemail roundcubemail
-$ psql roundcubemail
+$ createuser -P roundcube
+$ createdb -O roundcube -E UNICODE roundcubemail
+$ psql -U roundcube -f SQL/postgres.initial.sql roundcubemail
 
-roundcubemail =# ALTER USER roundcube WITH PASSWORD 'the_new_password';
-roundcubemail =# \c - roundcubemail
-roundcubemail => \i SQL/postgres.initial.sql
-
-All this has been tested with PostgreSQL 8.0.x and 7.4.x. Older
-versions don't have a -O option for the createdb, so if you are
-using that version you'll have to change ownership of the DB later.
+Note: in some system configurations you might need to add '-U postgres' to
+createuser and createdb commands.
 
 
-CONFIGURATION
-=============
+* Microsoft SQL Server
+----------------------
+Language/locale of the database must be set to us_english (1033). More info
+on this at http://trac.roundcube.net/ticket/1488918.
 
-Change the files in config/* according your to environment and your needs.
-Details about the config paramaters can be found in the config files.
+
+Database cleaning
+-----------------
+To keep your database slick and clean we recommend to periodically execute
+bin/cleandb.sh which finally removes all records that are marked as deleted.
+Best solution is to install a cronjob running this script daily.
+
+
+MANUAL CONFIGURATION
+====================
+
+First of all, copy the sample configuration file config/config.inc.php.sample
+to config/config.inc.php and make the necessary adjustments according to your
+environment and your needs. More configuration options can be copied from the
+config/defaults.inc.php file into your local config.inc.php file as needed.
+Read the comments above the individual configuration options to find out what
+they do or read http://trac.roundcube.net/wiki/Howto_Install for even more
+guidance.
+
+You can also modify the default .htaccess file. This is necessary to
+increase the allowed size of file attachments, for example:
+	php_value       upload_max_filesize     2M
+
+
+SECURE YOUR INSTALLATION
+========================
+
+Access through the webserver to the following directories should be denied:
+
+  /config
+  /temp
+  /logs
+
+Roundcube uses .htaccess files to protect these directories, so be sure to
+allow override of the Limit directives to get them taken into account. The
+package also ships a .htaccess file in the root directory which defines some
+rewrite rules. In order to properly secure your installation, please enable
+mod_rewrite for Apache webserver and double check access to the above listed
+directories and their contents is denied.
+
+NOTE: In Apache 2.4, support for .htaccess files has been disabled by
+default. Therefore you first need to enable this in your Apache main or
+virtual host config by with:
+
+ AllowOverride all
 
 
 UPGRADING
 =========
-If you already have a previous version of RoundCube installed,
+
+If you already have a previous version of Roundcube installed,
 please refer to the instructions in UPGRADING guide.
 
 
+OPTIMISING
+==========
+
+There are two forms of optimisation here, compression and caching, both aimed
+at increasing an end user's experience using Roundcube Webmail. Compression
+allows the static web pages to be delivered with less bandwidth. The index.php
+of Roundcube Webmail already enables compression on its output. The settings
+below allow compression to occur for all static files. Caching sets HTTP 
+response headers that enable a user's web client to understand what is static
+and how to cache it.
+
+The caching directives used are:
+ * Etags - sets at tag so the client can request is the page has changed
+ * Cache-control - defines the age of the page and that the page is 'public'
+   This enables clients to cache javascript files that don't have private 
+   information between sessions even if using HTTPS. It also allows proxies
+   to share the same cached page between users.
+ * Expires - provides another hint to increase the lifetime of static pages.
+
+For more information refer to RFC 2616.
+
+Side effects:
+-------------
+These directives are designed for production use. If you are using this in
+a development environment you may get horribly confused if your webclient
+is caching stuff that you changed on the server. Disabling the expires 
+parts below should save you some grief.
+
+If you are changing the skins, it is recommended that you copy content to 
+a different directory apart from 'default'.
+
+Apache:
+-------
+To enable these features in apache the following modules need to be enabled:
+ * mod_deflate
+ * mod_expires
+ * mod_headers
+
+The optimisation is already included in the .htaccess file in the top 
+directory of your installation.
+
+If you are using Apache version 2.2.9 and later, in the .htaccess file
+change the 'append' word to 'merge' for a more correct response. Keeping
+as 'append' shouldn't cause any problems though changing to merge will 
+eliminate the possibility of duplicate 'public' headers in Cache-control.
+
+Lighttpd:
+---------
+With Lightty the addition of Expire: tags by mod_expire is incompatible with
+the addition of "Cache-control: public". Using Cache-control 'public' is 
+used below as it is assumed to give a better caching result.
+
+Enable modules in server.modules:
+    "mod_setenv"
+    "mod_compress"
+
+Mod_compress is a server side cache of compressed files to improve its performance.
+
+$HTTP["host"] == "www.example.com" {
+
+    static-file.etags = "enable"
+    # http://redmine.lighttpd.net/projects/lighttpd/wiki/Etag.use-mtimeDetails
+    etag.use-mtime = "enable"
+
+    # http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ModSetEnv
+    $HTTP["url"] =~ "^/roundcubemail/(plugins|skins|program)" {
+        setenv.add-response-header  = ( "Cache-Control" => "public, max-age=2592000")
+    }
+
+    # http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:ModCompress
+    # set compress.cache-dir to somewhere outside the docroot.
+    compress.cache-dir   = var.statedir + "/cache/compress"
+
+    compress.filetype = ("text/plain", "text/html", "text/javascript", "text/css", "text/xml", "image/gif", "image/png")
+}
+
+
+KNOWN ISSUES
+============
+
+Installations with uw-imap server should set imap_disabled_caps = array('ESEARCH')
+in main configuration file. ESEARCH implementation in this server is broken (#1489184).
