# Foundation elements

> Set up the Organizations, Ledgers, Assets, and Account Types that everything else in Midaz is built on.

The **Foundation** section is where you set up the structure that the rest of Midaz sits on. Create it once, at the start of a new environment, before opening accounts or running transactions.

You will work with four elements here:

* **Organization** — The top-level entity that owns one or more ledgers. Usually represents your company or business unit (for example, *Acme Bank*).
* **Ledger** — The isolated book of records where accounts, balances, and transactions live. Most teams use one ledger per product or line of business (for example, *Retail BRL Ledger*).
* **Asset** — A currency or instrument that accounts can hold and move, identified by a code (for example, `BRL`, `USD`, or `USDC`). Every account is tied to one asset.
* **Account Type** — A label that classifies accounts so they can be referenced consistently in Accounting Routes (for example, `customer`, `treasury`, `fee`, or `revenue`).
