+# Hystrix: Latency and Fault Tolerance for Distributed Systems
-Hystrix is a fault and latency tolerance library designed to isolate points of access to remote systems, services and 3rd party libraries, stop cascading failure and enable resilience in complex environments where failure is inevitable.
+Hystrix is a latency and fault tolerance library designed to isolate points of access to remote systems, services and 3rd party libraries, stop cascading failure and enable resilience in complex distributed systems where failure is inevitable.
+
+## Full Documentation
+
+See the [Wiki](Hystrix/wiki) for full documentation, examples, operational details and other information.
+
+See the [Javadoc](http://netflix.github.com/Hystrix/javadoc) for the API.
+
+## What does it do?
+
+#### 1) Latency and Fault Tolerance
+
+Stop cascading failures. Fallbacks and graceful degradation. Fail fast and rapid recovery.
+
+Thread and semaphore isolation with circuit breakers.
+
+#### 2) Realtime Operations
+
+Realtime monitoring and configuration changes. Watch service and property changes take effect immediately as they spread across a fleet.
+
+Be alerted, make decisions, affect change and see results in seconds.
+
+#### 3) Concurrency
+
+Parallel execution. Concurrency aware request caching. Automated batching through request collapsing.
+
+## Download or Build
+
+You need Java 6 or later.
+
+Binaries and dependency information for Maven, Ivy, Gradle and others can be found at [http://search.maven.org](http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22com.netflix.hystrix%22%20AND%20a%3A%22hystrix-core%22).
+
+Details on building can be found on the [Getting Started](Hystrix/wiki/Getting-Started) page of the wiki.
+
+To build:
+
+```java
+$ git clone git@github.com:Netflix/Hystrix.git
+$ cd Hystrix/
+$ ./gradlew build
+```
+
+
+## Hello World!
+
+Code to be isolated is wrapped inside the run() method of a HystrixCommand similar to the following:
+
+```java
+public class CommandHelloWorld extends HystrixCommand<String> {
+
+ private final String name;
+
+ public CommandHelloWorld(String name) {
+ super(HystrixCommandGroupKey.Factory.asKey("ExampleGroup"));
+ this.name = name;
+ }
+
+ @Override
+ protected String run() {
+ return "Hello " + name + "!";
+ }
+}
+```
+
+This command could be used like this:
+
+```java
+String s = new CommandHelloWorld("Bob").execute();
+Future<String> s = new CommandHelloWorld("Bob").queue();
+```
+
+More examples and information can be found in the [How To Use](Hystrix/wiki/How-To-Use) section.
+
+Example source code can be found in the [hystrix-examples](Hystrix/tree/master/hystrix-examples/src/main/java/com/netflix/hystrix/examples) module.
