-## "net" Package
-
-TinyGo's "net" package is ported from Go.  The port offers a subset of Go's
-"net" package.  The subset maintains Go 1 compatiblity guarantee.  A Go
-application that uses "net" will most-likey just work on TinyGo if the usage is
-within the subset offered.  (There may be external constraints such as limited
-SRAM on some targets that may limit full "net" functionality).
-
-Continue below for details on using "net" and "net/http" packages.
-
-See src/net/READMD.md in the TinyGo repo for more details on maintaining
-TinyGo's "net" package.
-
-## Using "net" Package
-
-Ideally, TinyGo's "net" package would be Go's "net" package and applications
-using "net" would just work, as-is.  TinyGo's net package is a partial port of
-Go's net package, so some things may not work because they have not been
-ported.
-
-There are a few features excluded during the porting process, in particular:
-
-- No IPv6 support
-- No DualStack support
-
-Run ```go doc -all ./src/net``` in TinyGo repo to see full listing of what has
-been ported.  Here is a list of things known to work.  You can find examples
-of these at [examples/net](examples/net/).
-
-### What is Known to Work
-
-(These are all IPv4 only).
-
-- TCP client and server
-- UDP client
-- TLS client
-- HTTP client and server
-- HTTPS client
-- NTP client (UDP)
-- MQTT client (paho & natiu)
-- WebSocket client and server
-
-Multiple sockets can be opened in a single app.  For example, the app could run
-as an http server listen on port :80 and also use NTP to get the current time
-or send something over MQTT.  There is a practical limit to the number of
-active sockets per app, around 8 or 10, so don't go crazy.
-
-Applications using Go's net package will need a few setup steps to work with
-TinyGo's net package.  The steps are required before using "net".
-
-### Step 1: Probe to Load Network Driver
-
-Call Probe() to load the correct network driver for your target.  Probe()
-allows the app to work on multiple targets.
-
-```go
-package main
-
-import (
-	"tinygo.org/x/drivers/netlink/probe"
-)
-
-func main() {
-
-	// load network driver for target
-	link, dev := probe.Probe()
-
-	...	
-}
-```
-
-Probe() will load the driver with default configuration for the target.  For
-custom configuration, the app can open code Probe() for the target
-requirements.
-
-Probe() returns a [Netlinker](netlink/README.md) and a
-[Netdever](netdev/README.md), interfaces implemented by the network driver.
-Next, we'll use the Netlinker interface to connect the target to an IP network.
-
-### Step 2: Connect to an IP Network
-
-Before the net package is fully functional, we need to connect the target to an
-IP network.
-
-```go
-package main
-
-import (
-	"tinygo.org/x/drivers/netlink"
-	"tinygo.org/x/drivers/netlink/probe"
-)
-
-func main() {
-
-	// load network driver for target
-	link, _ := probe.Probe()
-
-	// Connect target to IP network
-	link.NetConnect(&netlink.ConnectParams{
-		Ssid:       "my SSID",
-		Passphrase: "my passphrase",
-	})
-
-	// OK to use "net" from here on
-	...	
-}
-```
-
-Optionally, get notified of IP network connects and disconnects:
-
-```go
-	link.Notify(func(e netlink.Event) {
-		switch e {
-		case netlink.EventNetUp:   println("Network UP")
-		case netlink.EventNetDown: println("Network DOWN")
-	})
-```
-
-Here is an example of an http server listening on port :8080:
-
-```go
-package main
-
-import (
-	"fmt"
-	"net/http"
-
-	"tinygo.org/x/drivers/netlink"
-	"tinygo.org/x/drivers/netlink/probe"
-)
-
-func HelloServer(w http.ResponseWriter, r *http.Request) {
-	fmt.Fprintf(w, "Hello, %s!", r.URL.Path[1:])
-}
-
-func main() {
-
-	// load network driver for target
-	link, _ := probe.Probe()
-
-	// Connect target to IP network
-	link.NetConnect(&netlink.ConnectParams{
-		Ssid:       "my SSID",
-		Passphrase: "my passphrase",
-	})
-
-	// Serve it up
-	http.HandleFunc("/", HelloServer)
-	http.ListenAndServe(":8080", nil)
-}
-```
-
-## Using "net/http" Package
-
-TinyGo's net/http package is a partial port of Go's net/http package, providing
-a subset of the full net/http package.  There are a few features excluded
-during the porting process, in particular:
-
-- No HTTP/2 support
-- No TLS support for HTTP servers (no https servers)
-- HTTP client request can't be reused
-
-HTTP client methods (http.Get, http.Head, http.Post, and http.PostForm) are
-functional.  Dial clients support both HTTP and HTTPS URLs.
-
-HTTP server methods and objects are mostly ported, but for HTTP only; HTTPS
-servers are not supported.
-
-HTTP request and response handling code is mostly ported, so most the intricacy
-of parsing and writing headers is handled as in the full net/http package.
-
-Run ```go doc -all ./src/net/http``` in TinyGo repo to see full listing.
-
-## Using "crypto/tls" Package
-
-TinyGo's TLS support (crypto/tls) relies on hardware offload of the TLS
-protocol.  This is different from Go's crypto/tls package which handles the TLS
-protocol in software.
-
-TinyGo's TLS support is only available for client applications.  You can
-http.Get() to an https:// address, but you cannot http.ListenAndServeTLS() an
-https server.
-
-The offloading hardware has pre-defined TLS certificates built-in.
-
-## Using Sockets
-
-The Netdever interface is a BSD socket-like interface so an application can make direct
-socket calls, bypassing the "net" package for the lowest overhead.
-
-Here is a simple TCP client application using direct sockets:
-
-```go
-package main
-
-import (
-	"net"  // only need to parse IP address
-
-	"tinygo.org/x/drivers/netdev"
-	"tinygo.org/x/drivers/netlink"
-	"tinygo.org/x/drivers/netlink/probe"
-)
-
-func main() {
-
-	// load network driver for target
-	link, dev := probe.Probe()
-
-	// Connect target to IP network
-	link.NetConnect(&netlink.ConnectParams{
-		Ssid:       "my SSID",
-		Passphrase: "my passphrase",
-	})
-
-	// omit error handling
-
-	sock, _ := dev.Socket(netdev.AF_INET, netdev.SOCK_STREAM, netdev.IPPROTO_TCP)
-
-        dev.Connect(sock, "", net.ParseIP("10.0.0.100"), 8080)
-	dev.Send(sock, []bytes("hello"), 0, 0)
-
-	dev.Close(sock)
-	link.NetDisconnect()
-}
-```
