+=====================
+Setting everything up
+=====================
+
+| In this tutorial, we'll teach you how to scrape http://www.dmoz.org, a websites directory.
+| We'll assume that you've checked and fulfilled the requirements specified in the Download page, and that Scrapy is already installed in your system.
+
+For starting a new project, enter the directory where you'd like your project to be located, and run::
+
+    scrapy-admin.py startproject dmoz
+
+As long as Scrapy is well installed and the path is set, this should create a directory called "dmoz"
+containing the following files:
+
+* *scrapy-ctl.py* - the project's control script. It's used for running the different tasks (like "crawl" and "parse"). We'll talk more about this later.
+* *scrapy_settings.py* - the project's settings file.
+* *items.py* - were you define the different kinds of items you're going to scrape.
+* *spiders* - directory where you'll later place your spiders.
+* *templates* - directory containing some templates for newly created spiders, and where you can put your own.
+
+| Ok, now that you have your project's structure defined, the last thing to do is to set your PYTHONPATH to your project's directory.
+| You can do this by adding this to your .bashrc file:
+
+::
+
+    export PYTHONPATH=/path/to/your/project
+
+
+Now you can continue with the next part of the tutorial.

+================
+Our first spider
+================
+
+| Ok, the time to write our first spider has come.
+| Make sure you're standing on your project's directory and run:
+
+::
+
+    ./scrapy-ctl genspider dmoz dmoz.org
+
+This should create a file called dmoz.py under the *spiders* directory looking similar to this::
+
+    # -*- coding: utf8 -*-<
+    import re
+    from scrapy.xpath import HtmlXPathSelector
+    from scrapy.item import ScrapedItem
+    from scrapy.link.extractors import RegexLinkExtractor
+    from scrapy.contrib.spiders import CrawlSpider, Rule
+
+    class DmozSpider(CrawlSpider):
+        domain_name = "dmoz.org"
+        start_urls = ['http://www.dmoz.org/']
+
+        rules = (
+            Rule(RegexLinkExtractor(allow=(r'Items/', ), 'parse_item', follow=True)
+        )
+
+        def parse_item(self, response):
+            #xs = HtmlXPathSelector(response)
+            #i = ScrapedItem()
+            #i.attribute('site_id', xs.x("//input[@id="sid"]/@value"))
+            #i.attribute('name', xs.x("//div[@id='name']"))
+            #i.attribute('description', xs.x("//div[@id='description']"))
+            #return [i]
+
+    SPIDER = DmozSpider()
