Had anybody installed bbPress? How to fill out config file.

I do not understand, what to fill into a Config file.
That is why it does not sign me in and does not show graphics.

<?php

// ** MySQL settings ** //
define(‘BBDB_NAME’, ‘wordpress’); // The name of the database
define(‘BBDB_USER’, ‘admin’); // Your MySQL username
define(‘BBDB_PASSWORD’, ‘******’); // …and password
define(‘BBDB_HOST’, ‘localhost’); // 99% chance you won’t need to change this value

// Change the prefix if you want to have multiple forums in a single database.
$bb_table_prefix = ‘bb_’; // Only letters, numbers and underscores please!

// If your bbPress URL is http://bbpress.example.com/forums/ , the examples would be correct.
// Adjust the domain and path to suit your actual URL.
// Just the domain name; no directories or path. There should be no trailing slash here.
$bb->domain = ‘http://my-cool-forums.example.com&#8217;; // Example: ‘http://bbpress.example.com&#8217;
// There should be both a leading and trailing slash here. ‘/’ is fine if the site is in root.
$bb->path = ‘/’; // Example: ‘/forums/’

// What are you going to call me?
$bb->name = ‘New bbPress Site’;

// This must be set before running the install script.
$bb->admin_email = ‘you@example.com’;

// Set to true if you want pretty permalinks.
$bb->mod_rewrite = false;

// The number of topics that show on each page.
$bb->page_topics = 30;

// A user can edit a post for this many minutes after submitting.
$bb->edit_lock = 60;

// Your timezone offset. Example: -7 for Pacific Daylight Time.
$bb->gmt_offset = 0;

// Change this to localize bbPress. A corresponding MO file for the
// chosen language must be installed to bb-includes/languages.
// For example, install de.mo to bb-includes/languages and set BBLANG to ‘de’
// to enable German language support.
define(‘BBLANG’, ”);

// Your Akismet Key. You do not need a key to run bbPress, but if you want to take advantage
// of Akismet’s powerful spam blocking, you’ll need one. You can get an Akismet key at
// http://wordpress.com/api-keys/
$bb->akismet_key = ”; // Example: ‘0123456789ab’

// The rest is only useful if you are integrating bbPress with WordPress.
// If you’re not, just leave the rest as it is.

$bb->wp_table_prefix = ”; // WordPress table prefix. Example: ‘wp_’;
$bb->wp_home = ”; // WordPress – Options->General: Blog address (URL) // No trailing slash. Example: ‘http://example.com&#8217;
$bb->wp_siteurl = ”; // WordPress – Options->General: WordPress address (URL) // No trailing slash. Example: ‘http://example.com&#8217;

/* Stop editing */

if ( !defined(‘BBPATH’) )
define(‘BBPATH’, dirname(__FILE__) . ‘/’ );

//if ( !defined(‘BBPATH’) )
// define(‘BBPATH’, dirname(bbpress) . ‘/’ );
