+## Usage
+
+
+
+### Read bindata with NewWithSourceInstance
+
+```shell
+go get -u github.com/jteeuwen/go-bindata/...
+cd examples/migrations && go-bindata -pkg migrations .
+```
+
+```go
+import (
+  "github.com/golang-migrate/migrate/v4"
+  "github.com/golang-migrate/migrate/v4/source/go_bindata"
+  "github.com/golang-migrate/migrate/v4/source/go_bindata/examples/migrations"
+)
+
+func main() {
+  // wrap assets into Resource
+  s := bindata.Resource(migrations.AssetNames(),
+    func(name string) ([]byte, error) {
+      return migrations.Asset(name)
+    })
+    
+  d, err := bindata.WithInstance(s)
+  m, err := migrate.NewWithSourceInstance("go-bindata", d, "database://foobar")
+  m.Up() // run your migrations and handle the errors above of course
+}
+```
+
+### Read bindata with URL (todo)
+
+This will restore the assets in a tmp directory and then
+proxy to source/file. go-bindata must be in your `$PATH`.
+
+```
+migrate -source go-bindata://examples/migrations/bindata.go
+```
