+Create http server listening on unix sockets and systemd socket activated fds
+
+## Quick Usage
+
+ go get go.balki.me/anyhttp
+
+Just replace `http.ListenAndServe` with `anyhttp.ListenAndServe`.
+
+```diff
+- http.ListenAndServe(addr, h)
++ anyhttp.ListenAndServe(addr, h)
+```
+
+## Address Syntax
+
+### Unix socket
+
+Syntax
+
+ unix/<path to socket>
+
+Examples
+
+ unix/relative/path.sock
+ unix//var/run/app/absolutepath.sock
+
+### Systemd Socket activated fd:
+
+Syntax
+
+ sysd/fdidx/<fd index starting at 0>
+ sysd/fdname/<fd name set using FileDescriptorName socket setting >
+
+Examples:
+
+ # First (or only) socket fd passed to app
+ sysd/fdidx/0
+
+ # Socket with FileDescriptorName
+ sysd/fdname/myapp
+
+ # Using default name
+ sysd/fdname/myapp.socket
+
+### TCP port
+
+If the address is a number less than 65536, it is assumed as a port and passed
+as `http.ListenAndServe(":<port>",...)` Anything else is directly passed to
+`http.ListenAndServe` as well. Below examples should work
+
+ :http
+ :8888
+ 127.0.0.1:8080
+
+## Idle server auto shutdown
+
+When using systemd socket activation, idle servers can be shut down to save on
+resources. They will be restarted with socket activation when new request
+arrives. Quick example for the case. (Error checking skipped for brevity)
+
+```go
+addrType, httpServer, done, _ := anyhttp.Serve(addr, idle.WrapHandler(nil))
+if addrType == anyhttp.SystemdFD {
+ idle.Wait(30 * time.Minute)
+ httpServer.Shutdown(context.TODO())
+}
+<-done
+```

-## Idle server auto shutdown
-
-When using systemd socket activation, idle servers can be shut down to save on
-resources. They will be restarted with socket activation when new request
-arrives. Quick example for the case. (Error checking skipped for brevity)

-```go

-if addrType == anyhttp.SystemdFD {
- idle.Wait(30 * time.Minute)
