 # Storage
 
-This package is used by the discovery service to register machines inside the cluster. It is also used to store cluster's metadata.
+The goal of `pkg/store` is to abstract common store operations for multiple Key/Value backends.
+
+For example, you can use it to store your metadata or for service discovery to register machines and endpoints inside your cluster.
+
+As of now, `pkg/store` offers support for `Consul`, `Etcd` and `Zookeeper`.

-To be elligible as a **discovery backend** only, a K/V store implementation should at least offer `Get`, `Put`, `WatchRange`, `GetRange`.
+In the case of Swarm and to be eligible as a **discovery backend** only, a K/V store implementation should at least offer `Get`, `Put`, `WatchTree` and `List`.
+
+`Put` should support usage of `ttl` to be able to remove entries in case of a node failure.
 
 You can get inspiration from existing backends to create a new one. This interface could be subject to changes to improve the experience of using the library and contributing to a new backend.

+// objx - Go package for dealing with maps, slices, JSON and other data.
+//
+// Overview
+//
+// Objx provides the `objx.Map` type, which is a `map[string]interface{}` that exposes
+// a powerful `Get` method (among others) that allows you to easily and quickly get
+// access to data within the map, without having to worry too much about type assertions,
+// missing data, default values etc.
+//
+// Pattern
+//
+// Objx uses a preditable pattern to make access data from within `map[string]interface{}'s
+// easy.
+//
+// Call one of the `objx.` functions to create your `objx.Map` to get going:
+//
+//     m, err := objx.FromJSON(json)
+//
+// NOTE: Any methods or functions with the `Must` prefix will panic if something goes wrong,
+// the rest will be optimistic and try to figure things out without panicking.
+//
+// Use `Get` to access the value you're interested in.  You can use dot and array
+// notation too:
+//
+//     m.Get("places[0].latlng")
+//
+// Once you have saught the `Value` you're interested in, you can use the `Is*` methods
+// to determine its type.
+//
+//     if m.Get("code").IsStr() { /* ... */ }
+//
+// Or you can just assume the type, and use one of the strong type methods to
+// extract the real value:
+//
+//     m.Get("code").Int()
+//
+// If there's no value there (or if it's the wrong type) then a default value
+// will be returned, or you can be explicit about the default value.
+//
+//     Get("code").Int(-1)
+//
+// If you're dealing with a slice of data as a value, Objx provides many useful
+// methods for iterating, manipulating and selecting that data.  You can find out more
+// by exploring the index below.
+//
+// Reading data
+//
+// A simple example of how to use Objx:
+//
+//     // use MustFromJSON to make an objx.Map from some JSON
+//     m := objx.MustFromJSON(`{"name": "Mat", "age": 30}`)
+//
+//     // get the details
+//     name := m.Get("name").Str()
+//     age := m.Get("age").Int()
+//
+//     // get their nickname (or use their name if they
+//     // don't have one)
+//     nickname := m.Get("nickname").Str(name)
+//
+// Ranging
+//
+// Since `objx.Map` is a `map[string]interface{}` you can treat it as such.  For
+// example, to `range` the data, do what you would expect:
+//
+//     m := objx.MustFromJSON(json)
+//     for key, value := range m {
+//
+//       /* ... do your magic ... */
+//
+//     }

+// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
+//
+// Example Usage
+//
+// The following is a complete example using assert in a standard test function:
+//    import (
+//      "testing"
+//      "github.com/stretchr/testify/assert"
+//    )
+//
+//    func TestSomething(t *testing.T) {
+//
+//      var a string = "Hello"
+//      var b string = "Hello"
+//
+//      assert.Equal(t, a, b, "The two words should be the same.")
+//
+//    }
+//
+// if you assert many times, use the below:
+//
+//    import (
+//      "testing"
+//      "github.com/stretchr/testify/assert"
+//    )
+//
+//    func TestSomething(t *testing.T) {
+//      assert := assert.New(t)
+//
+//      var a string = "Hello"
+//      var b string = "Hello"
+//
+//      assert.Equal(a, b, "The two words should be the same.")
+//    }
+//
+// Assertions
+//
+// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
+// All assertion functions take, as the first argument, the `*testing.T` object provided by the
+// testing framework. This allows the assertion funcs to write the failings and other details to
+// the correct place.
+//
+// Every assertion function also takes an optional string message as the final argument,
+// allowing custom error messages to be appended to the message the assertion method outputs.
+//
+// Here is an overview of the assert functions:
+//
+//    assert.Equal(t, expected, actual [, message [, format-args]])
+//
+//    assert.EqualValues(t, expected, actual [, message [, format-args]])
+//
+//    assert.NotEqual(t, notExpected, actual [, message [, format-args]])
+//
+//    assert.True(t, actualBool [, message [, format-args]])

+//
+//    assert.Empty(t, actualObject [, message [, format-args]])
+//
+//    assert.NotEmpty(t, actualObject [, message [, format-args]])
+//
+//    assert.Len(t, actualObject, expectedLength, [, message [, format-args]])
+//
+//    assert.Error(t, errorObject [, message [, format-args]])
+//
+//    assert.NoError(t, errorObject [, message [, format-args]])
+//
+//    assert.EqualError(t, theError, errString [, message [, format-args]])
+//
+//    assert.Implements(t, (*MyInterface)(nil), new(MyObject) [,message [, format-args]])
+//
+//    assert.IsType(t, expectedObject, actualObject [, message [, format-args]])
+//
+//    assert.Contains(t, stringOrSlice, substringOrElement [, message [, format-args]])
+//
+//    assert.NotContains(t, stringOrSlice, substringOrElement [, message [, format-args]])
+//
+//    assert.Panics(t, func(){
+//
+//	    // call code that should panic
+//
+//    } [, message [, format-args]])
+//

+// Provides a system by which it is possible to mock your objects and verify calls are happening as expected.
+//
+// Example Usage
+//
+// The mock package provides an object, Mock, that tracks activity on another object.  It is usually
+// embedded into a test object as shown below:
+//
+//   type MyTestObject struct {
+//     // add a Mock object instance
+//     mock.Mock
+//
+//     // other fields go here as normal
+//   }
+//
+// When implementing the methods of an interface, you wire your functions up
+// to call the Mock.Called(args...) method, and return the appropriate values.
+//
+// For example, to mock a method that saves the name and age of a person and returns
+// the year of their birth or an error, you might write this:
+//
+//     func (o *MyTestObject) SavePersonDetails(firstname, lastname string, age int) (int, error) {
+//       args := o.Called(firstname, lastname, age)
+//       return args.Int(0), args.Error(1)
+//     }
+//
+// The Int, Error and Bool methods are examples of strongly typed getters that take the argument
+// index position. Given this argument list:
+//
+//     (12, true, "Something")
+//
+// You could read them out strongly typed like this:
+//
+//     args.Int(0)
+//     args.Bool(1)
+//     args.String(2)
+//
+// For objects of your own type, use the generic Arguments.Get(index) method and make a type assertion:
+//
+//     return args.Get(0).(*MyObject), args.Get(1).(*AnotherObjectOfMine)
+//
+// This may cause a panic if the object you are getting is nil (the type assertion will fail), in those
+// cases you should check for nil first.
