 #### Changing the database, table, column Collation
 
 I personally have used [How to easily convert utf8 tables to utf8mb4 in MySQL 5.5 - Database Administrators Stack Exchange](https://dba.stackexchange.com/a/104866), **but**, as pointed out by the comments, with `SET foreign_key_checks = 0;` before you would run the generated queries and `SET foreign_key_checks = 1;` after you ran the generated queries.
+
+#### Creating Database User
+
+These are sample queries to create a database user named `fivenet` with "full" access to the database (`database_name`).
+You are expected to change the password in the first query and specify the right database name in the `GRANT` query second line.
+
+```sql
+CREATE USER 'fivenet'@'%' IDENTIFIED BY 'password';
+GRANT ALL PRIVILEGES ON 'database_name'.* TO 'fivenet'@'%';
+```
