+# Google APIs Client Library for Go
+
+## Status
+[![Build Status](https://travis-ci.org/google/google-api-go-client.png)](https://travis-ci.org/google/google-api-go-client)
+
+These are auto-generated Go libraries from the Google Discovery Service's JSON description files of the available "new style" Google APIs.
+
+Due to the auto-generated nature of this collection of libraries, complete APIs or specific versions can appear or go away without notice.
+As a result, you should always locally vendor any API(s) that your code relies upon.

+Getting started documentation:

+* https://github.com/google/google-api-go-client/blob/master/GettingStarted.md
+
+In summary:
+
+```
+$ go get google.golang.org/api/storage/v1
+$ go get google.golang.org/api/tasks/v1
+$ go get google.golang.org/api/moderator/v1
+... etc ...
+```
+
+For docs, see e.g.:
+
+* https://godoc.org/google.golang.org/api/storage/v1
+
+The package of a given import is the second-to-last component, before the version number.

+## Application Default Credentials Example
+
+Application Default Credentials provide a simplified way to obtain credentials
+for authenticating with Google APIs.
+
+The Application Default Credentials authenticate as the application itself,
+which make them great for working with Google Cloud APIs like Storage or
+Datastore. They are the recommended form of authentication when building
+applications that run on Google Compute Engine or Google App Engine.
+
+Default credentials are provided by the `golang.org/x/oauth2/google` package. To use them, add the following import:
+
+```
+import "golang.org/x/oauth2/google"
+```
+
+Some credentials types require you to specify scopes, and service entry points may not inject them. If you encounter this situation you may need to specify scopes as follows:
+
+```
+import (
+        "golang.org/x/net/context"
+        "golang.org/x/oauth2/google"
+        "google.golang.org/api/compute/v1"
+)
+
+func main() {
+        // Use oauth2.NoContext if there isn't a good context to pass in.
+        ctx := context.Background()
+
+        client, err := google.DefaultClient(ctx, compute.ComputeScope)
+        if err != nil {
+                //...
+        }
+        computeService, err := compute.New(client)
+        if err != nil {
+                //...
+        }
+}
+```
+
+If you need a `oauth2.TokenSource`, use the `DefaultTokenSource` function:
+
+```
+ts, err := google.DefaultTokenSource(ctx, scope1, scope2, ...)
+if err != nil {
+        //...
+}
+client := oauth2.NewClient(ctx, ts)
+```
