The Fundamentals tab is where you build intuition before touching anything Lerian-specific. It holds two short, plain-language series that approach the same subject — keeping a trustworthy record of money — from two angles.

Accounting

Explains the language underneath it: assets, liabilities, debits, credits, and how the books stay balanced.

Core Banking

Explains how a ledger system works: accounts, balances, movements, and the jobs a banking platform has to do.
They sit side by side because they answer different questions. One shows you the machine; the other shows you the grammar that machine is built on.

​
Which one first

If you’re unsure, start with Accounting. The vocabulary it teaches makes everything in Core Banking — and the rest of the docs — easier to follow.
