+# Manners
+
+A *polite* webserver for Go.
+
+Manners allows you to shut your Go webserver down gracefully, without dropping any requests. It can act as a drop-in replacement for the standard library's http.ListenAndServe function:
+
+```go
+func main() {
+  handler := MyHTTPHandler()
+  manners.ListenAndServe(":7000", handler)
+}
+```
+
+Then, when you want to shut the server down:
+
+```go
+manners.Close()
+```
+
+(Note that this does not block until all the requests are finished. Rather, the call to manners.ListenAndServe will stop blocking when all the requests are finished.)
+
+Manners ensures that all requests are served by incrementing a WaitGroup when a request comes in and decrementing it when the request finishes.
+
+If your request handler spawns Goroutines that are not guaranteed to finish with the request, you can ensure they are also completed with the `StartRoutine` and `FinishRoutine` functions on the server.
+
+### Known Issues
+
+Manners does not correctly shut down long-lived keepalive connections when issued a shutdown command. Clients on an idle keepalive connection may see a connection reset error rather than a close. See https://github.com/braintree/manners/issues/13 for details.
+
+### Compatability
+
+Manners 0.3.0 and above uses standard library functionality introduced in Go 1.3.
+
+### Installation
