 The YAML front matter has three important parameters:
 
 * `title:` - This is the title of the page enclosed in quotation marks. Each page must have a *unique* title
+* `slug:` - Set this to the same value as `title`, it will be slugified automatically by Jekyll.
 * `date:` - This field is needed for Jekyll to write a last-modified date. Initially, leave this field blank.

 Best practices:
 
 * Prefix the filenames with `010-foo.md`, `020-bar.md`, `030-baz.md`, etc. This allows room to add files in-between (eg, `005-qux.md`).  
-* Use the slug of the title as the filename. For example, if the title is "Getting Started with Drill", name the file `...-getting-started-with-drill.md`. If you're not sure what the slug is, you should be able to see it in the URL and then adjust (the URLs are auto-generated based on the title attribute).

   <article class="post-content">
-    <p>I’m excited to announce that the community has just released Drill 0.7, which includes <a href="https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12313820&amp;version=12327473">228 resolved JIRAs</a> and numerous enhancements such as:</p>
+    <p>The following summary of the book is (provided by the authors)[https://github.com/cgivre/drillbook].</p>
+
+<p><img src="images/cover.jpg" height="350" align="right" />In this practical book, Drill committers Charles Givre and Paul Rogers show analysts and data scientists how to query and analyze raw data using this powerful tool. Data scientists today spend about 80% of their time just gathering and cleaning data. With this book, you’ll learn how Drill helps you analyze data more effectively to drive down time to insight.</p>
 
 <ul>
-  <li>No dependency on UDP multicast. Drill can now work on EC2, as well as clusters with multiple subnets or multihomed configurations</li>
-  <li><a href="https://cwiki.apache.org/confluence/display/DRILL/Partition+Pruning">Automatic partition pruning</a> based on directory structures</li>
-  <li>New nested data functions: <a href="https://cwiki.apache.org/confluence/display/DRILL/KVGEN+Function">KVGEN</a> and <a href="https://cwiki.apache.org/confluence/display/DRILL/FLATTEN+Function">FLATTEN</a></li>
-  <li>Fast “schema” return. This provides a better experience when using BI tools</li>
-  <li>Hive 0.13 Metastore support</li>
-  <li>Improved performance for queries on JSON data</li>
+  <li>Use Drill to clean, prepare, and summarize delimited data for further analysis</li>
+  <li>Query file types including logfiles, Parquet, JSON, and other complex formats</li>
+  <li>Query Hadoop, relational databases, MongoDB, and Kafka with standard SQL</li>
+  <li>Connect to Drill programmatically using a variety of languages</li>
+  <li>Use Drill even with challenging or ambiguous file formats</li>
+  <li>Perform sophisticated analysis by extending Drill’s functionality with user-defined functions</li>
+  <li>Facilitate data analysis for network security, image metadata, and machine learning</li>
 </ul>

-<p>Druid supports multiple native queries to address sundry use-cases.  To fetch raw Druid rows, Druid’s API support two forms of query, <a href="https://Druid.apache.org/docs/latest/querying/select-query.html">Select</a> (no relation to SQL) and <a href="https://Druid.apache.org/docs/latest/querying/scan-query.html">Scan</a>.  Currently, this plugin uses the Select query API to fetch raw rows from Druid as json.</p>
-
-<h3 id="filter-push-down">Filter Push-Down</h3>
-
-<p>Filters are pushed down to native Druid filter structure, converting SQL where clauses to the respective Druid <a href="https://Druid.apache.org/docs/latest/querying/filters.html">Filters</a>.</p>
