+==== Vault Backend
+
+Spring Cloud Config Server also supports https://www.vaultproject.io[Vault] as a backend.
+****
+Vault is a tool for securely accessing secrets. A secret is anything
+that you want to tightly control access to, such as API keys, passwords,
+certificates, and more. Vault provides a unified interface to any secret,
+while providing tight access control and recording a detailed audit log.
+****
+
+For more information on Vault see the https://www.vaultproject.io/intro/index.html[Vault quickstart guide].
+
+To enable the config server to use a Vault backend you must run your config server
+with the `vault` profile.  For example in your config server's `application.properties`
+you can add `spring.profiles.active=vault`.
+
+By default the config server will assume your Vault server is running at
+`http://127.0.0.1:8200`.  It also will assume that the name of backend
+is `secret` and the key is `application`.  All of these defaults can be
+configured in your config server's `application.properties`.  Below is a
+table of configurable Vault properties.  All properties are prefixed with
+`spring.cloud.config.server.vault`.
+
+
+|===
+|Name |Default Value
+
+|host
+|127.0.0.1
+
+|port
+|8200
+
+|scheme
+|http
+
+|backend
+|secret
+
+|defaultKey
+|application
+
+|profileSeparator
+|,
+
+|===
+
+With you config server running you can make HTTP requests to the server to retrieve
+values from the Vault backend.  To do this you will need a token for your Vault server.
+
+First place some data in you Vault.  For example
+
+[source,sh]
+----
+$ vault write secret/application foo=bar baz=bam
+$ vault write secret/myapp foo=myappsbar
+----
+
+Now make the HTTP request to your config server to retrieve the values.
+
+`$ curl -X "GET" "http://localhost:8888/myapp/default" -H "X-Config-Token: yourtoken"`
+
+You should see a response similar to this after making the above request.
+
+[source,json]
+----
+{
+   "name":"myapp",
+   "profiles":[
+      "default"
+   ],
+   "label":null,
+   "version":null,
+   "state":null,
+   "propertySources":[
+      {
+         "name":"vault:myapp",
+         "source":{
+            "foo":"myappsbar"

+==== Vault
+
+When using Vault as a backend to your config server the client will need to
+supply a token for the server to retrieve values from Vault.  This token
+can be provided within the client by setting `spring.cloud.config.token`

+
+==== Nested Keys In Vault
+
+Vault supports the ability to nest keys in a value stored in Vault.  For example
+
+`echo -n '{"appA": {"secret": "appAsecret"}, "bar": "baz"}' | vault write secret/myapp -`
+
+This command will write a JSON object to your Vault.  To access these values in Spring
+you would use the traditional dot(.) annotation.  For example
+
+[source,java]
+----
+@Value("${appA.secret}")
+String name = "World";
+----
+
+The above code would set the `name` variable to `appAsecret`.
