 hledger-web is released along with hledger and supported on all the
 major platforms, while other add-ons may or may not be.
 
+#### autosync
+
+[ledger-autosync](https://bitbucket.org/egh/ledger-autosync/commits/all),
+which includes a `hledger-autosync` alias, downloads transactions
+from your bank(s) via OFX, and prints just the new ones as journal
+entries which you can add to your journal. It can also operate on .OFX
+files which you've downloaded manually. It can be a nice alternative
+to hledger's built-in CSV reader, especially if your bank supports OFX
+download.
+
+#### interest
+
+[hledger-interest](http://hackage.haskell.org/package/hledger-interest)
+computes interests for a given account. Using command line flags,
+the program can be configured to use various schemes for day-counting,
+such as act/act, 30/360, 30E/360, and 30/360isda. Furthermore, it
+supports a (small) number of interest schemes, i.e. annual interest
+with a fixed rate and the scheme mandated by the German BGB288
+(Basiszins für Verbrauchergeschäfte). See the package page for more.
+
+#### irr
+
+[hledger-irr](http://hackage.haskell.org/package/hledger-irr)
+computes the internal rate of return, also known as the effective
+interest rate, of a given investment. After specifying what account
+holds the investment, and what account stores the gains (or losses, or
+fees, or cost), it calculates the hypothetical annual rate of fixed
+rate investment that would have provided the exact same cash flow.
+See the package page for more.

 #### web
 
-The web command (provided by the [hledger-web](http://hackage.haskell.org/package/hledger-web) package)
+[hledger-web](http://hackage.haskell.org/package/hledger-web)
 provides a web-based user interface for viewing and modifying your ledger ([demo](http://demo.hledger.org)).
-It includes a more realistic account register view, and basic data entry and editing.

+Like the balance command, but with CSV output.
+
+#### equity.hs
+
+Like ledger's equity command, this prints a single journal entry with
+postings matching the current balance in each account (or the
+specified accounts) in the default journal. An entry like this is
+useful to carry over asset and liability balances when beginning a new
+journal file, eg at the start of the year.
+
+You can also use the same entry with signs reversed to close out the
+old file, resetting balances to 0. This means you'll see the correct
+asset/liability balances whether you use one file or a whole sequence
+of files as input to hledger.
+
+#### print-unique.hs
+
+Prints only journal entries which are unique (by description).
+
+#### register-csv.hs
+
+Like the register command, but with CSV output.
