+REQUIREMENTS AND NOTES
+----------------------
+
+Drupal requires:
+
+- A web server. Apache (version 2.0 or greater) is recommended.
+- PHP 5.2.4 (or greater) (http://www.php.net/).
+- One of the following databases:
+  - MySQL 5.0.15 (or greater) (http://www.mysql.com/).
+  - MariaDB 5.1.44 (or greater) (http://mariadb.org/). MariaDB is a fully
+    compatible drop-in replacement for MySQL.
+  - Percona Server 5.1.70 (or greater) (http://www.percona.com/). Percona
+    Server is a backwards-compatible replacement for MySQL.
+  - PostgreSQL 8.3 (or greater) (http://www.postgresql.org/).
+  - SQLite 3.3.7 (or greater) (http://www.sqlite.org/).
+
+For more detailed information about Drupal requirements, including a list of
+PHP extensions and configurations that are required, see "System requirements"
+(http://drupal.org/requirements) in the Drupal.org online documentation.
+
+For detailed information on how to configure a test server environment using a
+variety of operating systems and web servers, see "Local server setup"
+(http://drupal.org/node/157602) in the Drupal.org online documentation.
+
+Note that all directories mentioned in this document are always relative to the
+directory of your Drupal installation, and commands are meant to be run from
+this directory (except for the initial commands that create that directory).
+
+OPTIONAL SERVER REQUIREMENTS
+----------------------------
+
+- If you want to use Drupal's "Clean URLs" feature on an Apache web server, you
+  will need the mod_rewrite module and the ability to use local .htaccess
+  files. For Clean URLs support on IIS, see "Clean URLs with IIS"
+  (http://drupal.org/node/3854) in the Drupal.org online documentation.
+
+- If you plan to use XML-based services such as RSS aggregation, you will need
+  PHP's XML extension. This extension is enabled by default on most PHP
+  installations.
+
+- To serve gzip compressed CSS and JS files on an Apache web server, you will
+  need the mod_headers module and the ability to use local .htaccess files.
+
+- Some Drupal functionality (e.g., checking whether Drupal and contributed
+  modules need updates, RSS aggregation, etc.) require that the web server be
+  able to go out to the web and download information. If you want to use this
+  functionality, you need to verify that your hosting provider or server
+  configuration allows the web server to initiate outbound connections. Most web
+  hosting setups allow this.
+
+INSTALLATION
+------------
+
+1. Download and extract Drupal.
+
+   You can obtain the latest Drupal release from http://drupal.org -- the files
+   are available in .tar.gz and .zip formats and can be extracted using most
+   compression tools.
+
+   To download and extract the files, on a typical Unix/Linux command line, use
+   the following commands (assuming you want version x.y of Drupal in .tar.gz
+   format):
+
+     wget http://drupal.org/files/projects/drupal-x.y.tar.gz
+     tar -zxvf drupal-x.y.tar.gz
+
+   This will create a new directory drupal-x.y/ containing all Drupal files and
+   directories. Then, to move the contents of that directory into a directory
+   within your web server's document root or your public HTML directory,
+   continue with this command:
+
+     mv drupal-x.y/* drupal-x.y/.htaccess /path/to/your/installation
+
+2. Optionally, download a translation.
+
+   By default, Drupal is installed in English, and further languages may be
+   installed later. If you prefer to install Drupal in another language
+   initially:
+
+   - Download a translation file for the correct Drupal version and language
+     from the translation server: http://localize.drupal.org/translate/downloads
+
+   - Place the file into your installation profile's translations directory.
+     For instance, if you are using the Standard installation profile,
+     move the .po file into the directory:
+
+       profiles/standard/translations/
+
+   For detailed instructions, visit http://drupal.org/localize
+
+3. Create the Drupal database.
+
+   Because Drupal stores all site information in a database, you must create
+   this database in order to install Drupal, and grant Drupal certain database
+   privileges (such as the ability to create tables). For details, consult
+   INSTALL.mysql.txt, INSTALL.pgsql.txt, or INSTALL.sqlite.txt. You may also
+   need to consult your web hosting provider for instructions specific to your
+   web host.
+
+   Take note of the username, password, database name, and hostname as you
+   create the database. You will enter this information during the install.
+
+4. Run the install script.
+
+   To run the install script, point your browser to the base URL of your
+   website (e.g., http://www.example.com).
+
+   You will be guided through several screens to set up the database, add the
+   site maintenance account (the first user, also known as user/1), and provide
+   basic web site settings.
+
+   During installation, several files and directories need to be created, which
+   the install script will try to do automatically. However, on some hosting
+   environments, manual steps are required, and the install script will tell
+   you that it cannot proceed until you fix certain issues. This is normal and
+   does not indicate a problem with your server.
+
+   The most common steps you may need to perform are:
+
+   a. Missing files directory.
+
+      The install script will attempt to create a file storage directory in
+      the default location at sites/default/files (the location of the files
+      directory may be changed after Drupal is installed).
+
+      If auto-creation fails, you can make it work by changing permissions on
+      the sites/default directory so that the web server can create the files
+      directory within it for you. (If you are creating a multisite
+      installation, substitute the correct sites directory for sites/default;
+      see the Multisite Configuration section of this file, below.)
+
+      For example, on a Unix/Linux command line, you can grant everyone
+      (including the web server) permission to write to the sites/default
+      directory with this command:
+
+        chmod a+w sites/default
+
+      Be sure to set the permissions back after the installation is finished!
+      Sample command:
+
+        chmod go-w sites/default
+
+      Alternatively, instead of allowing the web server to create the files
+      directory for you as described above, you can create it yourself. Sample
+      commands from a Unix/Linux command line:
+
+        mkdir sites/default/files
+        chmod a+w sites/default/files
+
+   b. Missing settings file.
+
+      Drupal will try to automatically create a settings.php configuration file,
+      which is normally in the directory sites/default (to avoid problems when
+      upgrading, Drupal is not packaged with this file). If auto-creation fails,
+      you will need to create this file yourself, using the file
+      sites/default/default.settings.php as a template.
+
+      For example, on a Unix/Linux command line, you can make a copy of the
+      default.settings.php file with the command:
+
+        cp sites/default/default.settings.php sites/default/settings.php
+
+      Next, grant write privileges to the file to everyone (including the web
+      server) with the command:
+
+        chmod a+w sites/default/settings.php
+
+      Be sure to set the permissions back after the installation is finished!
+      Sample command:
+
+        chmod go-w sites/default/settings.php
+
+   c. Write permissions after install.
+
+      The install script will attempt to write-protect the settings.php file and
+      the sites/default directory after saving your configuration. If this
+      fails, you will be notified, and you can do it manually. Sample commands
+      from a Unix/Linux command line:
+
+        chmod go-w sites/default/settings.php
+        chmod go-w sites/default
+
+5. Verify that the site is working.
+
+   When the install script finishes, you will be logged in with the site
+   maintenance account on a "Welcome" page. If the default Drupal theme is not
+   displaying properly and links on the page result in "Page Not Found" errors,
+   you may be experiencing problems with clean URLs. Visit
+   http://drupal.org/getting-started/clean-urls to troubleshoot.
+
+6. Change file system storage settings (optional).
+
+   The files directory created in step 4 is the default file system path used to
+   store all uploaded files, as well as some temporary files created by
+   Drupal. After installation, you can modify the file system path to store
+   uploaded files in a different location.
+
+   It is not necessary to modify this path, but you may wish to change it if:
+
+   - Your site runs multiple Drupal installations from a single codebase (modify
+     the file system path of each installation to a different directory so that
+     uploads do not overlap between installations).
+
+   - Your site runs on a number of web servers behind a load balancer or reverse
+     proxy (modify the file system path on each server to point to a shared file
+     repository).
+
+   - You want to restrict access to uploaded files.
+
+   To modify the file system path:
+
+   a. Ensure that the new location for the path exists and is writable by the
+      web server. For example, to create a new directory named uploads and grant
+      write permissions, use the following commands on a Unix/Linux command
+      line:
+
+        mkdir uploads
+        chmod a+w uploads
+
+   b. Navigate to Administration > Configuration > Media > File system, and
+      enter the desired path. Note that if you want to use private file storage,
+      you need to first enter the path for private files and save the
+      configuration, and then change the "Default download method" setting and
+      save again.
+
+   Changing the file system path after files have been uploaded may cause
+   unexpected problems on an existing site. If you modify the file system path
+   on an existing site, remember to copy all files from the original location
+   to the new location.
+
+7. Revoke documentation file permissions (optional).
+
+   Some administrators suggest making the documentation files, especially
+   CHANGELOG.txt, non-readable so that the exact version of Drupal you are
+   running is slightly more difficult to determine. If you wish to implement
+   this optional security measure, from a Unix/Linux command line you can use
+   the following command:
+
+     chmod a-r CHANGELOG.txt
+
+   Note that the example only affects CHANGELOG.txt. To completely hide all
+   documentation files from public view, repeat this command for each of the
+   Drupal documentation files in the installation directory, substituting the
+   name of each file for CHANGELOG.txt in the example.
+
+   For more information on setting file permissions, see "Modifying Linux,
+   Unix, and Mac file permissions" (http://drupal.org/node/202483) or
+   "Modifying Windows file permissions" (http://drupal.org/node/202491) in the
+   Drupal.org online documentation.
+
+8. Set up independent "cron" maintenance jobs.
+
+   Many Drupal modules have tasks that must be run periodically, including the
+   Search module (building and updating the index used for keyword searching),
+   the Aggregator module (retrieving feeds from other sites), and the System
+   module (performing routine maintenance and pruning of database tables). These
+   tasks are known as "cron maintenance tasks", named after the Unix/Linux
+   "cron" utility.
+
+   When you install Drupal, its built-in cron feature is enabled, which
+   automatically runs the cron tasks periodically, triggered by people visiting
+   pages of your site. You can configure the built-in cron feature by navigating
+   to Administration > Configuration > System > Cron.
+
+   It is also possible to run the cron tasks independent of site visits; this is
+   recommended for most sites. To do this, you will need to set up an automated
+   process to visit the page cron.php on your site, which executes the cron
+   tasks.
+
+   The URL of the cron.php page requires a "cron key" to protect against
+   unauthorized access. Your site's cron key is automatically generated during
+   installation and is specific to your site. The full URL of the page, with the
+   cron key, is available in the "Cron maintenance tasks" section of the Status
+   report page at Administration > Reports > Status report.
+
+   As an example for how to set up this automated process, you can use the
+   crontab utility on Unix/Linux systems. The following crontab line uses the
+   wget command to visit the cron.php page, and runs each hour, on the hour:
+
+   0 * * * * wget -O - -q -t 1 http://example.com/cron.php?cron_key=YOURKEY
+
+   Replace the text "http://example.com/cron.php?cron_key=YOURKEY" in the
+   example with the full URL displayed under "Cron maintenance tasks" on the
+   "Status report" page.
+
+   More information about cron maintenance tasks is available at
+   http://drupal.org/cron, and sample cron shell scripts can be found in the
+   scripts/ directory. (Note that these scripts must be customized like the
+   above example, to add your site-specific cron key and domain name.)
+
+BUILDING AND CUSTOMIZING YOUR SITE
+----------------------------------
+
+A new installation of Drupal defaults to a very basic configuration. To extend
+your site, you use "modules" and "themes". A module is a plugin that adds
+functionality to Drupal, while a theme changes the look of your site. The core
+of Drupal provides several optional modules and themes, and you can download
+more at http://drupal.org/project/modules and http://drupal.org/project/themes
+
+Do not mix downloaded or custom modules and themes with Drupal's core modules
+and themes. Drupal's modules and themes are located in the top-level modules and
+themes directories, while the modules and themes you add to Drupal are normally
+placed in the sites/all/modules and sites/all/themes directories. If you run a
+multisite installation, you can also place modules and themes in the
+site-specific directories -- see the Multisite Configuration section, below.
+
+Never edit Drupal's core modules and themes; instead, use the hooks available in
+the Drupal API. To modify the behavior of Drupal, develop a module as described
+at http://drupal.org/developing/modules. To modify the look of Drupal, create a
+subtheme as described at http://drupal.org/node/225125, or a completely new
+theme as described at http://drupal.org/documentation/theme
+
+MULTISITE CONFIGURATION
+-----------------------
+
+A single Drupal installation can host several Drupal-powered sites, each with
+its own individual configuration.
+
+Additional site configurations are created in subdirectories within the 'sites'
+directory. Each subdirectory must have a 'settings.php' file, which specifies
+the configuration settings. The easiest way to create additional sites is to
+copy the 'default' directory and modify the 'settings.php' file as appropriate.
+The new directory name is constructed from the site's URL. The configuration for
+www.example.com could be in 'sites/example.com/settings.php' (note that 'www.'
+should be omitted if users can access your site at http://example.com/).
+
+Sites do not have to have a different domain. You can also use subdomains and
+subdirectories for Drupal sites. For example, example.com, sub.example.com, and
+sub.example.com/site3 can all be defined as independent Drupal sites. The setup
+for a configuration such as this would look like the following:
+
+  sites/default/settings.php
+  sites/example.com/settings.php
+  sites/sub.example.com/settings.php
+  sites/sub.example.com.site3/settings.php
+
+When searching for a site configuration (for example www.sub.example.com/site3),
+Drupal will search for configuration files in the following order, using the
+first configuration it finds:
+
+  sites/www.sub.example.com.site3/settings.php
+  sites/sub.example.com.site3/settings.php
+  sites/example.com.site3/settings.php
+  sites/www.sub.example.com/settings.php
+  sites/sub.example.com/settings.php
+  sites/example.com/settings.php
+  sites/default/settings.php
+
+If you are installing on a non-standard port, the port number is treated as the
+deepest subdomain. For example: http://www.example.com:8080/ could be loaded
+from sites/8080.www.example.com/. The port number will be removed according to
+the pattern above if no port-specific configuration is found, just like a real
+subdomain.
+
+Each site configuration can have its own site-specific modules and themes in
+addition to those installed in the standard 'modules' and 'themes' directories.
+To use site-specific modules or themes, simply create a 'modules' or 'themes'
+directory within the site configuration directory. For example, if
+sub.example.com has a custom theme and a custom module that should not be
+accessible to other sites, the setup would look like this:
+
+  sites/sub.example.com/
+    settings.php
+    themes/custom_theme
+    modules/custom_module
+
+NOTE: for more information about multiple virtual hosts or the configuration
+settings, consult http://drupal.org/getting-started/6/install/multi-site
+
+For more information on configuring Drupal's file system path in a multisite
+configuration, see step 6 above.
