 #E_PDOStatement
 
-Drop in replacement for default PHP PDOStatement class allowing devs to view an interpolated version of a parameterized query. The result is generally suitable for logging activities, debugging and performance analysis.
+Extension to the default PHP PDOStatement class providing the ability to generate a version of a parameterized query with the parameters injected into the query string.
 
-#####Update (2015-10-24)
-Full PHPUnit Test Suite in place plus re-organization of code
+The result is generally suitable for logging activities, debugging and performance analysis.
 
-#####Update (2015-07-19)
-Now takes into account bound arguments' datatypes when compiling interpolated string (previously, all values were quoted when it's likely inappropriate to quote INT datatypes). This allows for viewing/using bound values in e.g. LIMIT clauses where the quotes would interfere with processing the resultant query.

 The result of this will be (on a MySQL database):
 
 ```
-INSERT INTO users SET username = 'admin', password = '45ab6941fed66456afe6239ab875e4fa'
+INSERT INTO posts SET content = 'There are several reasons you shouldn\'t do that, including [...]', title = 'Why You Shouldn\'t Do That', date = '2016-05-13'
 ```
 
 When correctly configured, the interpolated values are escaped appropriately for the database driver, allowing the generated string to be suitable for e.g. log files, backups, etc.
 
 E_PDOStatement supports pre-execution binding to both named and ? style parameter markers:
 ```php
-$query      = "INSERT INTO users SET username = ?, password = ?";
