+# Gratipay Finances
+
+This is [Gratipay](https://gratipay.com/)'s financial accounting system, which
+is based on [Ledger](http://ledger-cli.org/). We have a directory for each
+year, and an `NN.dat` file for each month. Our wrapper scripts are in the
+`bin/` directory; add it to your `PATH` for best results. Each month gets [a
+PR](https://github.com/gratipay/finances/pulls).
+
+[![status](https://api.travis-ci.org/gratipay/finances.svg)](https://travis-ci.org/gratipay/finances)
+
+
+## How Our Books are Organized
+
+The biggest reality in our finances is that we have **operations**—*our*
+money—and then we have **escrow**—*other people's* money. Never the
+twain shall meet (more or less). Beyond the basic accounting principle that
+assets must equal liabilities plus equity, nearly as important for Gratipay is
+that escrow assets must always equal escrow liability: when people think we're
+holding their money, we better be holding their money!
+
+Actually, though, our income from processing fees comes to us from our upstream
+processors commingled with escrow, *and* we want to keep our fee *income* as
+close to our fee *expenses* as possible (our *operating* income, of course,
+comes [through Gratipay](https://gratipay.com/Gratipay/) just like any other
+Gratipay Team).  To deal with this dual reality, we use a **fee buffer**.
+Ideally the balance in the fee buffer is zero, though of course it varies in
+practice.
+
+You'll see, then, that the assets on our balance sheet, as well as our income
+and expenses on our income statement, are broken down according to these three
+second-level categories: escrow, fee buffer, and operations. The fee buffer and
+operations on the income statement hit retained earnings on the balance sheet.
+Escrow on the income statement hits escrow liability on the balance sheet.
+
+Whereas the second-level categories are *logical*, our actual *physical* bank
+and processor accounts end up as third-level categories. So, for example, our
+actual balance at New Alliance Federal Credit Union is equal to the sum of
+these three balance sheet accounts:
+
+ - Assets:Escrow:New Alliance
+ - Assets:Fee Buffer:New Alliance
+ - Assets:Operations:New Alliance
+
+
+## Working on the Finances
+
+First, you'll need [Ledger](http://ledger-cli.org/) (v3),
+[Python](https://www.python.org/) (v2.7), a [text
+editor](https://en.wikipedia.org/wiki/Text_editor), and a [command
+line](https://en.wikipedia.org/wiki/Command-line_interface). Then basically
+what you're gonna do is edit the dat file for the month you're working on, and
+then, from the root of your clone of this repo, run:
+
+```
+clear && test.py && balance-sheet.py && income-statement.py
+```
+
+That'll check for errors (we also have CI set up [at
+Travis](https://travis-ci.org/gratipay/finances)) and then show you a balance
+sheet and income statement.
+
+
+### Style
+
+Here are some style notes for the dat files:
+
+ 1. Group transactions together conceptually.
+
+ 1. Transactions should be generally date-sorted, but it's okay to fudge that a
+    little for the sake of (1).
+
+ 1. Record debits first.
+
+ 1. Symmetry is nice. 
+
+ 1. Use comments! Especially for weird stuff.
+
+
+### Access
+
+Many accounting tasks require access to Gratipay's bank and payment processor
+statements. If you're interested in helping out with such tasks, read [Inside
+Gratipay](http://inside.gratipay.com/) and then introduce yourself on [the
+Radar](http://inside.gratipay.com/howto/sweep-the-radar).
