+## Introduction
+
+This is just a hacky import script that reads YNAB exports (budget and
+register) and produces ledger output to stdout.
+
+## What it does
+
+It transforms the budget into a set of virtual transactions at the
+first of the month (or the day of the opening balance, for the first
+month) balanced against the Assets account.  Categorised transactions
+are exported with a non-balanced virtual posting to reduce the
+category amount.  It guesses whether an account should be an asset or
+a liability by its starting balance (anything positive denotes an
+asset), or by the presence of “credit” in the account name.  Memos are
+transformed into comments, either on the transaction or, for split
+transactions, on each posting.
+
+## Status
+
+It mostly works and has served its purpose for me.  It doesn’t work so
+well with off-budget accounts, although transferring into them seems
+fine, if they have any income it will not be categorised correctly.
+
+I don’t expect to develop this further, unless there is specific need.
+I haven’t tested it with currencies other than the British Pound.  Let
+me know if something doesn’t work (ideally with some test data) and
+I’ll try to fix it.
+
+If you want to fix it yourself, go ahead.  I’ll merge any pull request
+that looks reasonable and works with my own data.
