+# tally
+
+Fast, buffered, hierarchical stats collection in Java. [Go here](https://github.com/uber-go/tally) for the Go client.
+
+## Abstract
+
+Tally provides a common interface for emitting metrics, while letting you not worry about the velocity of metrics emission.
+
+By default it buffers counters, gauges and histograms at a specified interval but does not buffer timer values.  This is primarily so timer values can have all their values sampled if desired and if not they can be sampled as summaries or histograms independently by a reporter.
+
+## Structure
+
+- **Scope**: Keeps track of metrics, and their common metadata.
+- **Metrics**: Counters, Gauges, Timers and Histograms.
+- **Reporter**: Implemented by you. Accepts aggregated values from the scope. Forwards the aggregated values to your metrics ingestion pipeline.
+
+### Acquire a Scope
+
+```java
+// Implement as you will
+StatsReporter reporter = new MyStatsReporter();
+
+Map<String, String> tags = new HashMap<>(2, 1);
+tags.put("dc", "east-1");
+tags.put("type", "master");
+
+Scope scope = new RootScopeBuilder()
+    .reporter(reporter)
+    .tags(tags)
+    .reportEvery(Duration.ofSeconds(1))
+```
+
+### Get/Create a metric; use it
+```java
+Counter reqCounter = scope.counter("requests");
+reqCounter.inc(1);
+
+Gauge queueGauge = scope.gauge("queue_length");
+queueGauge.update(42);
+```
+
+### Report your metrics
+
+Use one of the inbuilt reporters or implement your own using the `StatsReporter` interface.
+
+## Example Usage
+
+Run the example by running:
+```
+$ ./gradlew run
+```
+This runs the `PrintStatsReporterExample` class in the `tally-example` project.
+
+## Artifacts Published
+
+All artifacts are published under the group `com.uber.m3`.
+
+1. `tally-statsd-fat`: Fat jar version of the tally StatsD reporter
+1. `tally-example`: Example usages with different reporters
+1. `tally-statsd`: The tally StatsD reporter
+1. `tally-core`: tally core functionality that includes interfaces and utilities to report metrics to M3
+
+## Versioning
+We follow semantic versioning outlined [here](http://semver.org/spec/v2.0.0.html). In summary,
+given a version of MAJOR.MINOR.PATCH (e.g. 1.2.0):
+
+- MAJOR version changes are breaking changes to the public API
+- MINOR version changes are backwards-compatible changes that include new functionality
+- PATCH version changes are backwards-compatible bug fixes
