Chart of accounts question

Hello.I am new to ERPNext.I have a question about the chart of accounts.When I created my account it automatically created a chart that I want to change to a standard chart from charts.erpnext.Can anyone help me please by telling me how exactly I can do this?Thanks.

Chart of accounts defaults based on your country. Which country have you selected during installation?

I have selected Romania,but it gave me a chart with very few critteria.The chart for Romania on charts.erpnext is much more complete.
