+# How to contribute
+
+GoTTY is MIT licensed and accepts contributions via GitHub pull requests. We also accepts feature requests on GitHub issues.
+
+## Reporting a bug
+
+Reporting a bug is always welcome and one of the best ways to contribute. A good bug report helps the developers to improve the product much easier. We therefore would like to ask you to fill out the quesions on the issue template as much as possible. That helps us to figure out what's happening and discover the root cause.
+
+
+## Requesting a new feature
+
+When you find that GoTTY cannot fullfill your requirements because of lack of ability, you may want to open a new feature request. In that case, please file a new issue with your usecase and requirements.
+
+
+## Opening a pull request
+
+### Code Style
+
+Please run `go fmt` on your Go code and make sure that your commits are organized for each logical change and your commit messages are in proper format (see below).
+
+[Go's official code style guide](https://github.com/golang/go/wiki/CodeReviewComments) is also helpful.
+
+### Format of the commit message
+
+When you write a commit message, we recommend include following information to make review easier and keep the history cleaerer.
+
+* What is the change
+* The reason for the change
+
+The following is an example:
+
+```
+Add something new to existing package
+
+Since the existing function lacks that mechanism for some purpose,
+this commit adds a new structure to provide it.
+```
+
+When your pull request is to add a new feature, we recommend add an actual usecase so that we can discuss the best way to achive your requirement. Opening a proposal issue in advance is another good way to start discussion of new features.
+
+
+## Contact
+
+If you have a trivial question about GoTTY for a bug or new feature, you can contact @i_yudai on Twitter (unfortunately, I cannot provide support on GoTTY though).

-# 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
-
-`go get github.com/braintree/manners`

-Package manners provides a wrapper for a standard net/http server that
-ensures all active HTTP client have completed their current request
-before the server shuts down.
-
-It can be used a drop-in replacement for the standard http package,
-or can wrap a pre-configured Server.
-
-eg.
-
-	http.Handle("/hello", func(w http.ResponseWriter, r *http.Request) {
-	  w.Write([]byte("Hello\n"))
-	})
-
-	log.Fatal(manners.ListenAndServe(":8080", nil))
-
-or for a customized server:
-
-	s := manners.NewWithServer(&http.Server{
-		Addr:           ":8080",
-		Handler:        myHandler,
-		ReadTimeout:    10 * time.Second,
-		WriteTimeout:   10 * time.Second,
-		MaxHeaderBytes: 1 << 20,
-	})
-	log.Fatal(s.ListenAndServe())
-
-The server will shut down cleanly when the Close() method is called:
-
-	go func() {
-		sigchan := make(chan os.Signal, 1)
-		signal.Notify(sigchan, os.Interrupt, os.Kill)
-		<-sigchan
-		log.Info("Shutting down...")
-		manners.Close()

-# cli.go
-cli.go is simple, fast, and fun package for building command line apps in Go. The goal is to enable developers to write fast and distributable command line applications in an expressive way.
-
-You can view the API docs here:
-http://godoc.org/github.com/codegangsta/cli
-
-## Overview
-Command line apps are usually so tiny that there is absolutely no reason why your code should *not* be self-documenting. Things like generating help text and parsing command flags/options should not hinder productivity when writing a command line app.
-
-**This is where cli.go comes into play.** cli.go makes command line programming fun, organized, and expressive!
-
-## Installation
-Make sure you have a working Go environment (go 1.1+ is *required*). [See the install instructions](http://golang.org/doc/install.html).
-
-To install `cli.go`, simply run:
-```
-$ go get github.com/codegangsta/cli
-```
-
-Make sure your `PATH` includes to the `$GOPATH/bin` directory so your commands can be easily used:
-```
-export PATH=$PATH:$GOPATH/bin
-```
-
-## Getting Started
-One of the philosophies behind cli.go is that an API should be playful and full of discovery. So a cli.go app can be as little as one line of code in `main()`. 
-
-``` go
-package main
-
-import (
-  "os"
-  "github.com/codegangsta/cli"
-)
-
-func main() {
-  cli.NewApp().Run(os.Args)
-}
-```
-
-This app will run and show help text, but is not very useful. Let's give an action to execute and some help documentation:
-
-``` go
-package main
-
-import (
-  "os"
-  "github.com/codegangsta/cli"
-)
-
-func main() {
-  app := cli.NewApp()
-  app.Name = "boom"
-  app.Usage = "make an explosive entrance"
-  app.Action = func(c *cli.Context) {
-    println("boom! I say!")
-  }
-  
-  app.Run(os.Args)
-}
-```
-
-Running this already gives you a ton of functionality, plus support for things like subcommands and flags, which are covered below.
-
-## Example
-
-Being a programmer can be a lonely job. Thankfully by the power of automation that is not the case! Let's create a greeter app to fend off our demons of loneliness!
-
-Start by creating a directory named `greet`, and within it, add a file, `greet.go` with the following code in it:
-
-``` go
-package main
-
-import (
-  "os"
-  "github.com/codegangsta/cli"
-)
-
-func main() {
-  app := cli.NewApp()
-  app.Name = "greet"
-  app.Usage = "fight the loneliness!"
-  app.Action = func(c *cli.Context) {
-    println("Hello friend!")
-  }
-
-  app.Run(os.Args)
-}
-```
-
-Install our command to the `$GOPATH/bin` directory:
-
-```
-$ go install
-```
-
-Finally run our new command:
-
-```
-$ greet
-Hello friend!
-```
-
-cli.go also generates some bitchass help text:
-```
-$ greet help
-NAME:
-    greet - fight the loneliness!
-
-USAGE:
-    greet [global options] command [command options] [arguments...]
-
-VERSION:
-    0.0.0
-
-COMMANDS:
-    help, h  Shows a list of commands or help for one command
-
-GLOBAL OPTIONS
-    --version	Shows version information
-```
-
-### Arguments
-You can lookup arguments by calling the `Args` function on `cli.Context`.
-
-``` go
-...
-app.Action = func(c *cli.Context) {
-  println("Hello", c.Args()[0])
-}
-...
-```
-
-### Flags
-Setting and querying flags is simple.
-``` go
-...
-app.Flags = []cli.Flag {
-  cli.StringFlag{
-    Name: "lang",
-    Value: "english",
-    Usage: "language for the greeting",
-  },
-}
-app.Action = func(c *cli.Context) {
-  name := "someone"
-  if len(c.Args()) > 0 {
-    name = c.Args()[0]
-  }
-  if c.String("lang") == "spanish" {
-    println("Hola", name)
-  } else {
-    println("Hello", name)
-  }
-}
-...
-```
-
-See full list of flags at http://godoc.org/github.com/codegangsta/cli
-
-#### Alternate Names
-
-You can set alternate (or short) names for flags by providing a comma-delimited list for the `Name`. e.g.
-
-``` go
-app.Flags = []cli.Flag {
-  cli.StringFlag{
-    Name: "lang, l",
-    Value: "english",
-    Usage: "language for the greeting",
-  },
-}
-```
-
-That flag can then be set with `--lang spanish` or `-l spanish`. Note that giving two different forms of the same flag in the same command invocation is an error.
-
-#### Values from the Environment
-
-You can also have the default value set from the environment via `EnvVar`.  e.g.
-
-``` go
-app.Flags = []cli.Flag {
-  cli.StringFlag{
-    Name: "lang, l",
-    Value: "english",
-    Usage: "language for the greeting",
-    EnvVar: "APP_LANG",
-  },
-}
-```
-
-The `EnvVar` may also be given as a comma-delimited "cascade", where the first environment variable that resolves is used as the default.
-
-``` go
-app.Flags = []cli.Flag {
-  cli.StringFlag{
-    Name: "lang, l",
-    Value: "english",
-    Usage: "language for the greeting",
-    EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG",
-  },
-}
-```
-
-### Subcommands
-
-Subcommands can be defined for a more git-like command line app.
-```go
-...
-app.Commands = []cli.Command{
-  {
-    Name:      "add",
-    Aliases:     []string{"a"},
-    Usage:     "add a task to the list",
-    Action: func(c *cli.Context) {
-      println("added task: ", c.Args().First())
-    },
-  },
-  {
-    Name:      "complete",
-    Aliases:     []string{"c"},
-    Usage:     "complete a task on the list",
-    Action: func(c *cli.Context) {
-      println("completed task: ", c.Args().First())
-    },
-  },
-  {
-    Name:      "template",
-    Aliases:     []string{"r"},
-    Usage:     "options for task templates",
-    Subcommands: []cli.Command{
-      {
-        Name:  "add",
-        Usage: "add a new template",
-        Action: func(c *cli.Context) {
-            println("new task template: ", c.Args().First())
-        },
-      },
-      {
-        Name:  "remove",
-        Usage: "remove an existing template",
-        Action: func(c *cli.Context) {
-          println("removed task template: ", c.Args().First())
-        },
-      },
-    },
-  },
-}
-...
-```
-
-### Bash Completion
-
-You can enable completion commands by setting the `EnableBashCompletion`
-flag on the `App` object.  By default, this setting will only auto-complete to
-show an app's subcommands, but you can write your own completion methods for
-the App or its subcommands.
-```go
-...
-var tasks = []string{"cook", "clean", "laundry", "eat", "sleep", "code"}
-app := cli.NewApp()
-app.EnableBashCompletion = true
-app.Commands = []cli.Command{
-  {
-    Name:  "complete",
-    Aliases: []string{"c"},
-    Usage: "complete a task on the list",
-    Action: func(c *cli.Context) {
-       println("completed task: ", c.Args().First())
-    },
-    BashComplete: func(c *cli.Context) {
-      // This will complete if no args are passed
-      if len(c.Args()) > 0 {
-        return
-      }
-      for _, t := range tasks {
-        fmt.Println(t)
-      }
-    },
-  }
-}
-...
-```
-
-#### To Enable
-
-Source the `autocomplete/bash_autocomplete` file in your `.bashrc` file while
-setting the `PROG` variable to the name of your program:
-
-`PROG=myprogram source /.../cli/autocomplete/bash_autocomplete`
-
-#### To Distribute
-
-Copy and modify `autocomplete/bash_autocomplete` to use your program name
-rather than `$PROG` and have the user copy the file into
-`/etc/bash_completion.d/` (or automatically install it there if you are
-distributing a package). Alternatively you can just document that users should
-source the generic `autocomplete/bash_autocomplete` with `$PROG` set to your
-program name in their bash configuration.
-
-## Contribution Guidelines
-Feel free to put up a pull request to fix a bug or maybe add a feature. I will give it a code review and make sure that it does not break backwards compatibility. If I or any other collaborators agree that it is in line with the vision of the project, we will work with you to get the code into a mergeable state and merge it into the master branch.
-
-If you have contributed something significant to the project, I will most likely add you as a collaborator. As a collaborator you are given the ability to merge others pull requests. It is very important that new code does not break existing code, so be careful about what code you do choose to merge. If you have any questions feel free to link @codegangsta to the issue in question and we can review it together.
-
-If you feel like you have contributed to the project but have not yet been added as a collaborator, I probably forgot to add you. Hit @codegangsta up over email and we will get it figured out.

-# Chat Example
-
-This application shows how to use use the
-[websocket](https://github.com/gorilla/websocket) package and
-[jQuery](http://jquery.com) to implement a simple web chat application.
-
-## Running the example
-
-The example requires a working Go development environment. The [Getting
-Started](http://golang.org/doc/install) page describes how to install the
-development environment.
-
-Once you have Go up and running, you can download, build and run the example
-using the following commands.
-
-    $ go get github.com/gorilla/websocket
-    $ cd `go list -f '{{.Dir}}' github.com/gorilla/websocket/examples/chat`
-    $ go run *.go
-
-To use the chat example, open http://localhost:8080/ in your browser.

-# UTF8Reader for Go
-
-UTF8Reader is a simple wrapper Reader that fills the given buffer with a "tail-safe" UTF8 byte sequence.
-
-## Tail-Safe?
-
-Let's say you have a buffer of 7 bytes and your Reader is going to fill your buffer with a UTF8 byte sequence.
-
-```go
-buf := make([]byte, 7)
-reader := strings.NewReader("いろは")
-
-reader.Read(buf)
-```
-
-The byte length of UTF8 characters is not fixed and some characters like the examples above have 3 byte length. There are others which have a single byte, 2 byte and 4 byte length as well. This means your buffer will be sometimes filled with incomplete bytes as an Unicode character at the tail.
-
-By `reader.Read(buf)`, your `buf` will be like below:
-
-```go
-[]byte{
-	// い
-	byte(0xe3), // 1
-	byte(0x81), // 2
-	byte(0x84), // 3
-	// ろ
-	byte(0xe3), // 4
-	byte(0x82), // 5
-	byte(0x8d), // 6
-	// は (incomplete)
-	byte(0xe3), // 7
-}
-```
-
-The last character `は` is incomplete and the buffer is now invalid as a UTF8 string.
-
-UTF8Reader detects incomplete bytes like above and aborts filling up the buffer in such cases.
-
-```go
-buf := make([]byte, 7)
-reader := strings.NewReader("いろは")
-utfReader := utf8reader.New(reader)
-
-utfReader.Read(buf)
-```
-
-Then you will get:
-
-```go
-[]byte{
-	// い
-	byte(0xe3), // 1
-	byte(0x81), // 2
-	byte(0x84), // 3
-	// ろ
-	byte(0xe3), // 4
-	byte(0x82), // 5
-	byte(0x8d), // 6
-}
-```
-Of course, bytes left behind will be used to fill up the buffer on next `Read()`.
-
-## Note
-
-UTF8Reader just checks incomplete bytes at the tail of the buffer. Even if the original byte sequence given to UTF8Reader is broken, UTF8Reader reports no errors and just fills up the buffer.

 ### Security Options
 
-By default, gotty doesn't allow clients to send any keystrokes or commands except terminal window resizing. When you want to permit clients to write input to the PTY, add the `-w` option. However, accepting input from remote clients is dangerous for most commands. When you need interaction with the PTY for some reasons, consider starting gotty with tmux or GNU Screen and run your main command on it (see "Sharing with Multiple Clients" section for detail).

-To restrict client access, you can use the `-c` option to enable the basic authentication. With option, clients need to input the specified username and passwords to connect to the gotty server. The `-r` option is a little bit casualer way to restrict access. With this option, gotty generates a random URL so that only people who know the URL can get access to the server.

Note that the credentical will be transmitted between the server and clients in plain text. For more strict authentication, consider the SSL/TLS client certificate authentication described below.
 
-All traffic between servers and clients are NOT encrypted by default. When you send secret information through gotty, we strongly recommend you use the `-t` option which enables TLS/SSL on the session. By default, gotty loads the crt and key files placed at `~/.gotty.crt` and `~/.gotty.key`. You can overwrite these file paths with the `--tls-cert` and `--tls-key` options. When you need to generate a self-signed certification file, you can use the `openssl` command.

+
+For additional security, you can use the SSL/TLS client certificate authentication by providing a CA certificate file to the `--tls-ca-crt` option (this option requires the `-t` or `--tls` to be set). This option requires all clients to send valid client certificates that are signed by the specified certification authority.

 ## Sharing with Multiple Clients
 
-Gotty starts a new process when a new client connects to the server. This means users cannot share a single terminal with others by default. However, you can use terminal multiplexers for sharing a single process with multiple clients.

 ## Architecture
 
-Gotty uses [hterm](https://groups.google.com/a/chromium.org/forum/#!forum/chromium-hterm) to run a JavaScript based terminal on web browsers. Gotty itself provides a websocket server that simply relays output from the PTY to clients and receives input from clients and forwards to the PTY. This hterm + websocket idea is highly inspired by [Wetty](https://github.com/krishnasrinivas/wetty).
+GoTTY uses [xterm.js](https://xtermjs.org/) and [hterm](https://groups.google.com/a/chromium.org/forum/#!forum/chromium-hterm) to run a JavaScript based terminal on web browsers. GoTTY itself provides a websocket server that simply relays output from the TTY to clients and receives input from clients and forwards it to the TTY. This hterm + websocket idea is inspired by [Wetty](https://github.com/krishnasrinivas/wetty).
+
+## Alternatives
+
+### Command line client
+
+* [gotty-client](https://github.com/moul/gotty-client): If you want to connect to GoTTY server from your terminal
+
+### Terminal/SSH on Web Browsers
+
+* [Secure Shell (Chrome App)](https://chrome.google.com/webstore/detail/secure-shell/pnhechapfaindjhompbnflcldabbghjo): If you are a chrome user and need a "real" SSH client on your web browser, perhaps the Secure Shell app is what you want
+* [Wetty](https://github.com/krishnasrinivas/wetty): Node based web terminal (SSH/login)
+* [ttyd](https://tsl0922.github.io/ttyd): C port of GoTTY with CJK and IME support
+
+### Terminal Sharing
+
+* [tmate](http://tmate.io/): Forked-Tmux based Terminal-Terminal sharing
+* [termshare](https://termsha.re): Terminal-Terminal sharing through a HTTP server
+* [tmux](https://tmux.github.io/): Tmux itself also supports TTY sharing through SSH)
