+# go-bindata-assetfs
+
+Serve embedded files from [jteeuwen/go-bindata](https://github.com/jteeuwen/go-bindata) with `net/http`.
+
+[GoDoc](http://godoc.org/github.com/elazarl/go-bindata-assetfs)
+
+### Installation
+
+Install with
+
+    $ go get github.com/jteeuwen/go-bindata/...
+    $ go get github.com/elazarl/go-bindata-assetfs/...
+
+### Creating embedded data
+
+Usage is identical to [jteeuwen/go-bindata](https://github.com/jteeuwen/go-bindata) usage,
+instead of running `go-bindata` run `go-bindata-assetfs`.
+
+The tool will create a `bindata_assetfs.go` file, which contains the embedded data.
+
+A typical use case is
+
+    $ go-bindata-assetfs data/...
+
+### Using assetFS in your code
+
+The generated file provides an `assetFS()` function that returns a `http.Filesystem`
+wrapping the embedded files. What you usually want to do is:
+
+    http.Handle("/", http.FileServer(assetFS()))
+
+This would run an HTTP server serving the embedded files.
+
+## Without running binary tool
+
+You can always just run the `go-bindata` tool, and then
+
+use
+
+     import "github.com/elazarl/go-bindata-assetfs"
+     ...
+     http.Handle("/",
+        http.FileServer(
+        &assetfs.AssetFS{Asset: Asset, AssetDir: AssetDir, Prefix: "data"}))
+
+to serve files embedded from the `data` directory.
