+import "filippo.io/edwards25519"
+```
+
+This library implements the edwards25519 elliptic curve, exposing the necessary APIs to build a wide array of higher-level primitives.
+Read the docs at [pkg.go.dev/filippo.io/edwards25519](https://pkg.go.dev/filippo.io/edwards25519).
+
+The code is originally derived from Adam Langley's internal implementation in the Go standard library, and includes George Tankersley's [performance improvements](https://golang.org/cl/71950). It was then further developed by Henry de Valence for use in ristretto255, and was finally [merged back into the Go standard library](https://golang.org/cl/276272) as of Go 1.17. It now tracks the upstream codebase and extends it with additional functionality.
+
+Most users don't need this package, and should instead use `crypto/ed25519` for signatures, `golang.org/x/crypto/curve25519` for Diffie-Hellman, or `github.com/gtank/ristretto255` for prime order group logic. However, for anyone currently using a fork of `crypto/internal/edwards25519`/`crypto/ed25519/internal/edwards25519` or `github.com/agl/edwards25519`, this package should be a safer, faster, and more powerful alternative.
+
+Since this package is meant to curb proliferation of edwards25519 implementations in the Go ecosystem, it welcomes requests for new APIs or reviewable performance improvements.

-# gitter
-Gitter API in Go
-https://developer.gitter.im
-
-#### Install
-
-`go get github.com/sromku/go-gitter`
-
-- [Initialize](#initialize)
-- [Users](#users)
-- [Rooms](#rooms)
-- [Messages](#messages)
-- [Stream](#stream)
-- [Faye (Experimental)](#faye-experimental)
-- [Debug](#debug)
-- [App Engine](#app-engine)
-
-##### Initialize
-``` Go
-api := gitter.New("YOUR_ACCESS_TOKEN")
-```
-
-##### Users
-
-- Get current user
-
-	``` Go
-	user, err := api.GetUser()
-	```
-
-##### Rooms
-
-- Get all rooms
-	``` Go
-	rooms, err := api.GetRooms()
-	```
-
-- Get room by id
-	``` Go
-	room, err := api.GetRoom("roomID")
-	```
-
-- Get rooms of some user
-	``` Go
-	rooms, err := api.GetRooms("userID")
-	```
-
-- Join room
-	``` Go
-	room, err := api.JoinRoom("roomID", "userID")
-	```
-	
-- Leave room
-	``` Go
-	room, err := api.LeaveRoom("roomID", "userID")
-	```
-
-- Get room id
-	``` Go
-	id, err := api.GetRoomId("room/uri")
-	```
-
-- Search gitter rooms
-	``` Go
-	rooms, err := api.SearchRooms("search/string")
-	```
-##### Messages
-
-- Get messages of room
-	``` Go
-	messages, err := api.GetMessages("roomID", nil)
-	```
-
-- Get one message
-	``` Go
-	message, err := api.GetMessage("roomID", "messageID")
-	```
-
-- Send message
-	``` Go
-	err := api.SendMessage("roomID", "free chat text")
-	```
-
-##### Stream
-
-Create stream to the room and start listening to incoming messages
-
-``` Go
-stream := api.Stream(room.Id)
-go api.Listen(stream)
-
-for {
-    event := <-stream.Event
-    switch ev := event.Data.(type) {
-    case *gitter.MessageReceived:
-        fmt.Println(ev.Message.From.Username + ": " + ev.Message.Text)
-    case *gitter.GitterConnectionClosed:
-        // connection was closed
-    }
-}
-```
-
-Close stream connection
-
-``` Go
-stream.Close()
-```
-
-##### Faye (Experimental)
-
-``` Go
-faye := api.Faye(room.ID)
-go faye.Listen()
-
-for {
-    event := <-faye.Event
-    switch ev := event.Data.(type) {
-    case *gitter.MessageReceived:
-        fmt.Println(ev.Message.From.Username + ": " + ev.Message.Text)
-    case *gitter.GitterConnectionClosed: //this one is never called in Faye
-        // connection was closed
-    }
-}
-```
-
-##### Debug
-
-You can print the internal errors by enabling debug to true
-
-``` Go
-api.SetDebug(true, nil)
-```
-
-You can also define your own `io.Writer` in case you want to persist the logs somewhere.
-For example keeping the errors on file
-
-``` Go
-logFile, err := os.Create("gitter.log")
-api.SetDebug(true, logFile)
-```
-
-##### App Engine
-
-Initialize app engine client and continue as usual
-
-``` Go
-c := appengine.NewContext(r)
-client := urlfetch.Client(c)
-
-api := gitter.New("YOUR_ACCESS_TOKEN")
-api.SetClient(client)
-```
