+# winston-transport
+
+The base `TransportStream` implementation for `winston >= 3`. Use these to
+write ecosystem Transports for `winston`.
+
+## Usage
+
+``` js
+const Transport = require('winston-transport');
+const util = require('util');
+
+//
+// Inherit from `winston-transport` so you can take advantage
+// of the base functionality and `.exceptions.handle()`.
+//
+module.exports = class CustomTransport extends Transport {
+  constructor(opts) {
+    super(opts);
+
+    //
+    // Consume any custom options here. e.g.:
+    // - Connection information for databases
+    // - Authentication information for APIs (e.g. loggly, papertrail,
+    //   logentries, etc.).
+    //
+  }
+
+  log(info, callback) {
+    setImmediate(() => {
+      this.emit('logged', info);
+    });
+
+    // Perform the writing to the remote service
+
+    callback();
+  }
+};
+```
+
+## Tests
+
+Tests are written with `mocha`, `nyc`, `assume`, and 
+`abstract-winston-transport`. They can be run with `npm`:
+
+``` bash
+npm test
+```
