+
+# Config HTTP Endpoint
+
+The `/config` endpoints create, update, delete and query central configuration
+entries registered with Consul.
+
+## Apply Configuration
+
+This endpoint creates or updates the given config entry.
+
+| Method | Path                         | Produces                   |
+| ------ | ---------------------------- | -------------------------- |
+| `PUT`  | `/config`                    | `application/json`         |
+
+The table below shows this endpoint's support for
+[blocking queries](/api/index.html#blocking-queries),
+[consistency modes](/api/index.html#consistency-modes),
+[agent caching](/api/index.html#agent-caching), and
+[required ACLs](/api/index.html#acls).
+
+| Blocking Queries | Consistency Modes | Agent Caching | ACL Required  |
+| ---------------- | ----------------- | ------------- | ------------- |
+| `NO`             | `none`            | `none`        | `service:write`<br>`operator:write`<sup>1</sup> |
+
+<sup>1</sup> The ACL required depends on the Kind of the config entry being updated:
+
+| Config Entry Kind | Required ACL     |
+| ----------------- | ---------------- |
+| service-defaults  | `service:write`  |
+| proxy-defaults    | `operator:write` |
+
+### Parameters
+
+- `dc` `(string: "")` - Specifies the datacenter to query. This will default to
+  the datacenter of the agent being queried. This is specified as part of the
+  URL as a query parameter.
+
+- `cas` `(int: 0)` - Specifies to use a Check-And-Set operation. If the index is 
+  0, Consul will only put the entry if it does not already exist. If the index is 
+  non-zero, the entry is only set if the current index matches the `ModifyIndex` 
+  of that entry.
+
+### Sample Payload
+
+
+```javascript
+{
+    "Kind": "service-defaults",
+    "Name": "web",
+    "Protocol": "http",
