+# phosphor-rest-server
+
+Phosphor REST server was the original OpenBMC webserver.  All of it's features
+have long since been implemented in
+[bmcweb](https://github.com/openbmc/bmcweb), and if you are looking for a
+webserver for your BMC, you should certainly use that before using this.
+Phosphor REST server is not maintained and very likely has security bugs.
