Subject: [PATCH] Updated README

With MySQL 5.6 default configuration is more strict and adds STRICT_TRANS_TABLES.

Added some info to configure MySQL properly. Better solution would be to make the schema correctly, defining optional columns as nullable.

+As of MySQL 5.6, default configuration sets the sql_mode value to
+
+```
+STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION
+```
+
+This 'STRICT_TRANS_TABLES' configuration results in SQL errors when no default value is defined on NOT NULL columns and the value is empty or invalid.
+
+You can edit this default config in ` /etc/my.cnf ` and change the sql_mode to remove the STRICT_TRANS_TABLES part
+
+```
+[mysqld]
+sql_mode=NO_ENGINE_SUBSTITUTION
+```
+
+Assuming your sql_mode is the default one, you can change the value directly on the run by running the following SQL Command
+
+```sql
+SET @@GLOBAL.sql_mode='NO_ENGINE_SUBSTITUTION', @@SESSION.sql_mode='NO_ENGINE_SUBSTITUTION'
+```
+
