+# Docker volume extension api.
+
+Go handler to create external volume extensions for Docker.
+
+## Usage
+
+This library is designed to be integrated in your program.
+
+1. Implement the `volume.Driver` interface.
+2. Initialize a `volume.Handler` with your implementation.
+3. Call either `ServeTCP` or `ServeUnix` from the `volume.Handler`.
+
+### Example using TCP sockets:
+
+```go
+ d := MyVolumeDriver{}
+ h := volume.NewHandler(d)
+ h.ServeTCP("test_volume", ":8080")
+```
+
+### Example using Unix sockets:
+
+```go
+ d := MyVolumeDriver{}
+ h := volume.NewHandler(d)
+ u, _ := user.Lookup("root")
+ gid, _ := strconv.Atoi(u.Gid)
+ h.ServeUnix("test_volume", gid)
+```
