+# axios // adapters
+
+The modules under `adapters/` are modules that handle dispatching a request and settling a returned `Promise` once a response is received.
+
+## Example
+
+```js
+var settle = require('./../core/settle');
+
+module.exports = function myAdapter(config) {
+  // At this point:
+  //  - config has been merged with defaults
+  //  - request transformers have already run
+  //  - request interceptors have already run
+  
+  // Make the request using config provided
+  // Upon response settle the Promise
+
+  return new Promise(function(resolve, reject) {
+  
+    var response = {
+      data: responseData,
+      status: request.status,
+      statusText: request.statusText,
+      headers: responseHeaders,
+      config: config,
+      request: request
+    };
+
+    settle(resolve, reject, response);
+
+    // From here:
+    //  - response transformers will run
+    //  - response interceptors will run
+  });
+}
+```
