 ## Installation
 * Clone or download this repository
+* With SQLite
 	* Create the sqlite3 database from the files in the _sql directory. The default name for the database file is "hpr.db" and should be located in the root of the project directory. The name and location can be set in the site.cfg file.
 	* Two sql helper scripts are available to generate an empty database or a database filled with test data.
 		- For an empty database: `cat Create_Database_Empty.sql | sqlite3 hpr.db`
 		- For a database with test data: `cat Create_Database_Test.sql | sqlite3 hpr.db`
 	* SQLite v3.8.3 or greater is recommended. CTE WITH clauses are used in some template queries. Must convert WITH 
 	  clauses to sub-queries when using earlier versions of SQLite.
+* With MySQL
+	* Create database hpr_hpr in the MySQL server from HPR dump file.
+		- ``sudo mysql --host=localhost < hpr.sql``
+	* Create a user that will be used by the site-generator.
+		- Suggested username: hpr-generator
+		- ``CREATE USER 'hpr-generator'@'localhost' IDENTIFIED BY '<password>';``
+	* Limit the user's privileges to EXECUTE and SELECT
+		- ``GRANT SELECT ON hpr_hpr.* TO 'hpr-generator'@'localhost';``
