# Do this first: Prerequisites for using the guides

The guides in this section all involve the movement of money to and from various accounts. In the real world, money should only enter your ledger from the @world account when real money moves into real accounts that you are tracking. However, to run the demonstrations in the guides, we need to seed the example accounts with funds.

This is not realistic and you should as a general rule never arbitrarily create money without a corresponding movement of money in the real world!

First, create a file called seed.num with the following contents:

Wow, that's really complex! I don't understand.

Broadly speaking, this Numscript will place 1000 coins in all the accounts we will use in these guides.

But really, right now, don't worry about understanding this complicated bit of Numscript. This script is only necessary to set up the Dunshire ledger we'll use in the following guides, and there is no need to fully understand it yet.

Then run it with

fctl ledger transactions num seed.num

You shouldn't need to, but you can always run this script as many times as necessary to ensure that all accounts are topped up with funds.

## VSCode extension​

Do you use VSCode? Would you like to have Numscript syntax highlighting? We have a Numscript VSCode extension to enable Numscript syntax highlighting.

## Resetting the Dunshire ledger​

If you find that you want a clean slate to start from, you can reset the Dunshire ledger in its entirety. If you followed the Hello World tutorial, then Formance Ledger is using the default SQLite storage method. Thus you can delete the Dunshire ledger by deleting the corresponding SQLite file, which is stored in ~/.numary/data/numary_dunshire.db.
