+Hi, figured we could actually use a changelog now:
+
+## 1.1.4 2017-04-21
+
+* Fix typo in package.json
+
+## 1.1.3 2017-04-21
+
+* Improve documentation and limit files included in the distribution.
+
+## 1.1.2 2016-03-15
+
+* Add tracker group cycle detection and tests for it
+
+## 1.1.1 2016-01-29
+
+* Fix a typo in stream completion tracker
+
+## 1.1.0 2016-01-29
+
+* Rewrote completion percent computation to be low impact– no more walking a
+  tree of completion groups every time we need this info.  Previously, with
+  medium sized tree of completion groups, even a relatively modest number of
+  calls to the top level `completed()` method would result in absurd numbers
+  of calls overall as it walked down the tree. We now, instead, keep track as
+  we bubble up changes, so the computation is limited to when data changes and
+  to the depth of that one branch, instead of _every_ node. (Plus, we were already
+  incurring _this_ cost, since we already bubbled out changes.)
+* Moved different tracker types out to their own files.
+* Made tests test for TOO MANY events too.
+* Standarized the source code formatting

+are-we-there-yet
+----------------
+
+Track complex hiearchies of asynchronous task completion statuses.  This is
+intended to give you a way of recording and reporting the progress of the big
+recursive fan-out and gather type workflows that are so common in async.
+
+What you do with this completion data is up to you, but the most common use case is to
+feed it to one of the many progress bar modules.
+
+Most progress bar modules include a rudamentary version of this, but my
+needs were more complex.
+
+Usage
+=====
+
+```javascript
+var TrackerGroup = require("are-we-there-yet").TrackerGroup
+
+var top = new TrackerGroup("program")
+
+var single = top.newItem("one thing", 100)
+single.completeWork(20)
+
+console.log(top.completed()) // 0.2
+
+fs.stat("file", function(er, stat) {
+  if (er) throw er
+  var stream = top.newStream("file", stat.size)
+  console.log(top.completed()) // now 0.1 as single is 50% of the job and is 20% complete
+                              // and 50% * 20% == 10%
+  fs.createReadStream("file").pipe(stream).on("data", function (chunk) {
+    // do stuff with chunk
+  })
+  top.on("change", function (name) {
+    // called each time a chunk is read from "file"
+    // top.completed() will start at 0.1 and fill up to 0.6 as the file is read
+  })
+})
+```
+
+Shared Methods
+==============
+
+* var completed = tracker.completed()
+
+Implemented in: `Tracker`, `TrackerGroup`, `TrackerStream`
+
+Returns the ratio of completed work to work to be done. Range of 0 to 1.
+
+* tracker.finish()
+
+Implemented in: `Tracker`, `TrackerGroup`
+
+Marks the tracker as completed. With a TrackerGroup this marks all of its
+components as completed.
+
+Marks all of the components of this tracker as finished, which in turn means
+that `tracker.completed()` for this will now be 1.
+
+This will result in one or more `change` events being emitted.
+
+Events
+======
+
+All tracker objects emit `change` events with the following arguments:
+
+```
+function (name, completed, tracker)
+```
+
+`name` is the name of the tracker that originally emitted the event,
+or if it didn't have one, the first containing tracker group that had one.
+
+`completed` is the percent complete (as returned by `tracker.completed()` method).
+
+`tracker` is the tracker object that you are listening for events on.
+
+TrackerGroup
+============
+
+* var tracker = new TrackerGroup(**name**)
+
+  * **name** *(optional)* - The name of this tracker group, used in change
+    notifications if the component updating didn't have a name. Defaults to undefined.
+
+Creates a new empty tracker aggregation group. These are trackers whose
+completion status is determined by the completion status of other trackers.
+
+* tracker.addUnit(**otherTracker**, **weight**)
+
+  * **otherTracker** - Any of the other are-we-there-yet tracker objects
+  * **weight** *(optional)* - The weight to give the tracker, defaults to 1.
+
+Adds the **otherTracker** to this aggregation group. The weight determines
+how long you expect this tracker to take to complete in proportion to other
+units.  So for instance, if you add one tracker with a weight of 1 and
+another with a weight of 2, you're saying the second will take twice as long
+to complete as the first.  As such, the first will account for 33% of the
+completion of this tracker and the second will account for the other 67%.
+
+Returns **otherTracker**.
+
+* var subGroup = tracker.newGroup(**name**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subGroup = tracker.addUnit(new TrackerGroup(name), weight)
+```
+
+* var subItem = tracker.newItem(**name**, **todo**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subItem = tracker.addUnit(new Tracker(name, todo), weight)
+```
+
+* var subStream = tracker.newStream(**name**, **todo**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subStream = tracker.addUnit(new TrackerStream(name, todo), weight)
+```
+
+* console.log( tracker.debug() )
+
+Returns a tree showing the completion of this tracker group and all of its
+children, including recursively entering all of the children.
+
+Tracker
+=======
+
+* var tracker = new Tracker(**name**, **todo**)
+
+  * **name** *(optional)* The name of this counter to report in change
+    events.  Defaults to undefined.
+  * **todo** *(optional)* The amount of work todo (a number). Defaults to 0.
+
+Ordinarily these are constructed as a part of a tracker group (via
+`newItem`).
+
+* var completed = tracker.completed()
+
+Returns the ratio of completed work to work to be done. Range of 0 to 1. If
+total work to be done is 0 then it will return 0.
+
+* tracker.addWork(**todo**)
+
+  * **todo** A number to add to the amount of work to be done.
+
+Increases the amount of work to be done, thus decreasing the completion
+percentage.  Triggers a `change` event.
+
+* tracker.completeWork(**completed**)
+
+  * **completed** A number to add to the work complete
+
+Increase the amount of work complete, thus increasing the completion percentage.
+Will never increase the work completed past the amount of work todo. That is,
+percentages > 100% are not allowed. Triggers a `change` event.
+
+* tracker.finish()
+
+Marks this tracker as finished, tracker.completed() will now be 1. Triggers
+a `change` event.
+
+TrackerStream
+=============
+
+* var tracker = new TrackerStream(**name**, **size**, **options**)
+
+  * **name** *(optional)* The name of this counter to report in change
+    events.  Defaults to undefined.
+  * **size** *(optional)* The number of bytes being sent through this stream.
+  * **options** *(optional)* A hash of stream options
+
+The tracker stream object is a pass through stream that updates an internal
+tracker object each time a block passes through.  It's intended to track
+downloads, file extraction and other related activities. You use it by piping
+your data source into it and then using it as your data source.
+
+If your data has a length attribute then that's used as the amount of work
+completed when the chunk is passed through.  If it does not (eg, object
+streams) then each chunk counts as completing 1 unit of work, so your size
+should be the total number of objects being streamed.
+
+* tracker.addWork(**todo**)
+
+  * **todo** Increase the expected overall size by **todo** bytes.
+
+Increases the amount of work to be done, thus decreasing the completion
+percentage.  Triggers a `change` event.
