 - use `aregister` for reviewing and reconciling real-world asset/liability accounts
 - use `register` for reviewing detailed revenues/expenses.
 
-`aregister` requires one argument: the account to report on.
-You can write either the full account name, or a case-insensitive regular expression 
-which will select the alphabetically first matched account.
-
-When there are multiple matches, the alphabetically-first choice can be surprising; 
-eg if you have `assets:per:checking 1` and `assets:biz:checking 2` accounts,
-`hledger areg checking` would select `assets:biz:checking 2`.
-It's just a convenience to save typing, so if in doubt, write the full account name,
-or a distinctive substring that matches uniquely.
+Note this command's non-standard, and required, first argument; it specifies the account whose register will be shown.
+You can write the account's name, or (to save typing) a case-insensitive infix regular expression matching the name,
+which selects the alphabetically first matched account.
+(For example, if you have `assets:personal checking` and `assets:business checking`,
+`hledger areg checking` would select `assets:business checking`.)
 
 Transactions involving subaccounts of this account will also be shown.
 `aregister` ignores depth limits, so its final total will always match 
 a historical balance report with similar arguments.
 
-Any additional arguments form a [query](#queries) which will filter the
-transactions shown. Note some queries will disturb the running balance,
-causing it to be different from the account's real-world running balance.
