+# News
+We are putting together plans for future changes. We obviously depend on all of you to take part in the planning for the future of goamz and execution of the plans. Other than the regulare 'issues' and 'pull requests' please also have a look at TODO.md.     
+
+It is inevitable that there will be backward-*in*compatible changes. Please subscribe to the google group to get all the news (it will only be used for announcements, all the technical discussions will happen on github).

+# GoAMZ
+
+[![Build Status](https://travis-ci.org/docker/goamz.png?branch=master)](https://travis-ci.org/docker/goamz)
+
+The _goamz_ package enables Go programs to interact with Amazon Web Services.
+
+This is a fork of the version [developed within Canonical](https://wiki.ubuntu.com/goamz) with additional functionality and services from [a number of contributors](https://github.com/docker/goamz/contributors)!
+
+The API of AWS is very comprehensive, though, and goamz doesn't even scratch the surface of it. That said, it's fairly well tested, and is the foundation in which further calls can easily be integrated. We'll continue extending the API as necessary - Pull Requests are _very_ welcome!
+
+The following packages are available at the moment:
+
+```
+github.com/docker/goamz/aws
+github.com/docker/goamz/cloudwatch
+github.com/docker/goamz/dynamodb
+github.com/docker/goamz/ec2
+github.com/docker/goamz/elb
+github.com/docker/goamz/iam
+github.com/docker/goamz/kinesis
+github.com/docker/goamz/s3
+github.com/docker/goamz/sqs
+github.com/docker/goamz/sns
+
+github.com/docker/goamz/exp/mturk
+github.com/docker/goamz/exp/sdb
+github.com/docker/goamz/exp/ses
+```
+
+Packages under `exp/` are still in an experimental or unfinished/unpolished state.
+
+## API documentation
+
+The API documentation is currently available at:
+
+[http://godoc.org/github.com/docker/goamz](http://godoc.org/github.com/docker/goamz)
+
+## How to build and install goamz
+
+Just use `go get` with any of the available packages. For example:
+
+* `$ go get github.com/docker/goamz/ec2`
+* `$ go get github.com/docker/goamz/s3`
+
+## Running tests
+
+To run tests, first install gocheck with:
+
+`$ go get launchpad.net/gocheck`
+
+Then run go test as usual:
+
+`$ go test github.com/docker/goamz/...`
+
+_Note:_ running all tests with the command `go test ./...` will currently fail as tests do not tear down their HTTP listeners.
+
+If you want to run integration tests (costs money), set up the EC2 environment variables as usual, and run:
+
+`$ gotest -i`

+# libtrust
+
+Libtrust is library for managing authentication and authorization using public key cryptography.
+
+Authentication is handled using the identity attached to the public key.
+Libtrust provides multiple methods to prove possession of the private key associated with an identity.
+ - TLS x509 certificates
+ - Signature verification
+ - Key Challenge
+
+Authorization and access control is managed through a distributed trust graph.
+Trust servers are used as the authorities of the trust graph and allow caching portions of the graph for faster access.
