+# 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.

-# Unblocking Mutex
-
-This simple package provides unblocking mutexes for those who don't want to write many `select` clauses or get confused by numerous channels.
-
-## Usage Example
-
-```go
-package main
-
-import (
-	"fmt"
-	"github.com/yudai/umutex"
-)
-
-func main() {
-	// Create mutex
-	mutex := umutex.New()
-
-	// First time, try should succeed
-	if mutex.TryLock() {
-		fmt.Println("SUCCESS")
-	} else {
-		fmt.Println("FAILURE")
-	}
-
-	// Second time, try should fail as it's locked
-	if mutex.TryLock() {
-		fmt.Println("SUCCESS")
-	} else {
-		fmt.Println("FAILURE")
-	}
-
-	// Unclock mutex
-	mutex.Unlock()
-
-	// Third time, try should succeed again
-	if mutex.TryLock() {
-		fmt.Println("SUCCESS")
-	} else {
-		fmt.Println("FAILURE")
-	}
-}
-```
-
-The output is;
-
-```sh
-SUCCESS
-FAILURE
-SUCCESS
-```
-
-`ForceLock()` method is also availale for normal blocking lock.

-2. License Grants and Conditions
-
-2.1. Grants
-
-     Each Contributor hereby grants You a world-wide, royalty-free,
-     non-exclusive license:
-
-     a. under intellectual property rights (other than patent or trademark)
-        Licensable by such Contributor to use, reproduce, make available,
-        modify, display, perform, distribute, and otherwise exploit its
-        Contributions, either on an unmodified basis, with Modifications, or as
-        part of a Larger Work; and
-
-     b. under Patent Claims of such Contributor to make, use, sell, offer for
-        sale, have made, import, and otherwise transfer either its Contributions
-        or its Contributor Version.
-
-2.2. Effective Date
-
-     The licenses granted in Section 2.1 with respect to any Contribution become
-     effective for each Contribution on the date the Contributor first distributes
-     such Contribution.
-
-2.3. Limitations on Grant Scope
-
-     The licenses granted in this Section 2 are the only rights granted under this
-     License. No additional rights or licenses will be implied from the distribution
-     or licensing of Covered Software under this License. Notwithstanding Section
-     2.1(b) above, no patent license is granted by a Contributor:
-
-     a. for any code that a Contributor has removed from Covered Software; or
-
-     b. for infringements caused by: (i) Your and any other third party’s
-        modifications of Covered Software, or (ii) the combination of its
-        Contributions with other software (except as part of its Contributor
-        Version); or
-
-     c. under Patent Claims infringed by Covered Software in the absence of its
-        Contributions.
-
-     This License does not grant any rights in the trademarks, service marks, or
-     logos of any Contributor (except as may be necessary to comply with the
-     notice requirements in Section 3.4).
-
-2.4. Subsequent Licenses
-
-     No Contributor makes additional grants as a result of Your choice to
-     distribute the Covered Software under a subsequent version of this License
-     (see Section 10.2) or under the terms of a Secondary License (if permitted
-     under the terms of Section 3.3).
-
-2.5. Representation
-
-     Each Contributor represents that the Contributor believes its Contributions
-     are its original creation(s) or it has sufficient rights to grant the
-     rights to its Contributions conveyed by this License.
-
-2.6. Fair Use
-
-     This License is not intended to limit any rights You have under applicable
-     copyright doctrines of fair use, fair dealing, or other equivalents.
-
-2.7. Conditions
-
-     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
-     Section 2.1.
-
-
-3. Responsibilities
-
-3.1. Distribution of Source Form
-
-     All distribution of Covered Software in Source Code Form, including any
-     Modifications that You create or to which You contribute, must be under the
-     terms of this License. You must inform recipients that the Source Code Form
-     of the Covered Software is governed by the terms of this License, and how
-     they can obtain a copy of this License. You may not attempt to alter or
-     restrict the recipients’ rights in the Source Code Form.
-
-3.2. Distribution of Executable Form
-
-     If You distribute Covered Software in Executable Form then:
-
-     a. such Covered Software must also be made available in Source Code Form,
-        as described in Section 3.1, and You must inform recipients of the
-        Executable Form how they can obtain a copy of such Source Code Form by
-        reasonable means in a timely manner, at a charge no more than the cost
-        of distribution to the recipient; and
-
-     b. You may distribute such Executable Form under the terms of this License,
-        or sublicense it under different terms, provided that the license for
-        the Executable Form does not attempt to limit or alter the recipients’
-        rights in the Source Code Form under this License.
-
-3.3. Distribution of a Larger Work
-
-     You may create and distribute a Larger Work under terms of Your choice,
-     provided that You also comply with the requirements of this License for the
-     Covered Software. If the Larger Work is a combination of Covered Software
-     with a work governed by one or more Secondary Licenses, and the Covered
-     Software is not Incompatible With Secondary Licenses, this License permits
-     You to additionally distribute such Covered Software under the terms of
-     such Secondary License(s), so that the recipient of the Larger Work may, at
-     their option, further distribute the Covered Software under the terms of
-     either this License or such Secondary License(s).
-
-3.4. Notices
-
-     You may not remove or alter the substance of any license notices (including
-     copyright notices, patent notices, disclaimers of warranty, or limitations
-     of liability) contained within the Source Code Form of the Covered
-     Software, except that You may alter any license notices to the extent
-     required to remedy known factual inaccuracies.
-
-3.5. Application of Additional Terms
-
-     You may choose to offer, and to charge a fee for, warranty, support,
-     indemnity or liability obligations to one or more recipients of Covered
-     Software. However, You may do so only on Your own behalf, and not on behalf
-     of any Contributor. You must make it absolutely clear that any such
-     warranty, support, indemnity, or liability obligation is offered by You
-     alone, and You hereby agree to indemnify every Contributor for any
-     liability incurred by such Contributor as a result of warranty, support,
-     indemnity or liability terms You offer. You may include additional
-     disclaimers of warranty and limitations of liability specific to any
-     jurisdiction.
-
-4. Inability to Comply Due to Statute or Regulation
-
-   If it is impossible for You to comply with any of the terms of this License
-   with respect to some or all of the Covered Software due to statute, judicial
-   order, or regulation then You must: (a) comply with the terms of this License
-   to the maximum extent possible; and (b) describe the limitations and the code
-   they affect. Such description must be placed in a text file included with all
-   distributions of the Covered Software under this License. Except to the
-   extent prohibited by statute or regulation, such description must be
-   sufficiently detailed for a recipient of ordinary skill to be able to
-   understand it.
-
-5. Termination
-
-5.1. The rights granted under this License will terminate automatically if You
-     fail to comply with any of its terms. However, if You become compliant,
-     then the rights granted under this License from a particular Contributor
-     are reinstated (a) provisionally, unless and until such Contributor
-     explicitly and finally terminates Your grants, and (b) on an ongoing basis,
-     if such Contributor fails to notify You of the non-compliance by some
-     reasonable means prior to 60 days after You have come back into compliance.
-     Moreover, Your grants from a particular Contributor are reinstated on an
-     ongoing basis if such Contributor notifies You of the non-compliance by
-     some reasonable means, this is the first time You have received notice of
-     non-compliance with this License from such Contributor, and You become
-     compliant prior to 30 days after Your receipt of the notice.
-
-5.2. If You initiate litigation against any entity by asserting a patent
-     infringement claim (excluding declaratory judgment actions, counter-claims,
-     and cross-claims) alleging that a Contributor Version directly or
-     indirectly infringes any patent, then the rights granted to You by any and
-     all Contributors for the Covered Software under Section 2.1 of this License
-     shall terminate.
-
-5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
-     license agreements (excluding distributors and resellers) which have been
-     validly granted by You or Your distributors under this License prior to
-     termination shall survive termination.
-
-6. Disclaimer of Warranty
-
-   Covered Software is provided under this License on an “as is” basis, without
-   warranty of any kind, either expressed, implied, or statutory, including,
-   without limitation, warranties that the Covered Software is free of defects,
-   merchantable, fit for a particular purpose or non-infringing. The entire
-   risk as to the quality and performance of the Covered Software is with You.
-   Should any Covered Software prove defective in any respect, You (not any
-   Contributor) assume the cost of any necessary servicing, repair, or
-   correction. This disclaimer of warranty constitutes an essential part of this
-   License. No use of  any Covered Software is authorized under this License
-   except under this disclaimer.
-
-7. Limitation of Liability
-
-   Under no circumstances and under no legal theory, whether tort (including
-   negligence), contract, or otherwise, shall any Contributor, or anyone who
-   distributes Covered Software as permitted above, be liable to You for any
-   direct, indirect, special, incidental, or consequential damages of any
-   character including, without limitation, damages for lost profits, loss of
-   goodwill, work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses, even if such party shall have been
-   informed of the possibility of such damages. This limitation of liability
-   shall not apply to liability for death or personal injury resulting from such
-   party’s negligence to the extent applicable law prohibits such limitation.
-   Some jurisdictions do not allow the exclusion or limitation of incidental or
-   consequential damages, so this exclusion and limitation may not apply to You.
-
-8. Litigation
-
-   Any litigation relating to this License may be brought only in the courts of
-   a jurisdiction where the defendant maintains its principal place of business
-   and such litigation shall be governed by laws of that jurisdiction, without
-   reference to its conflict-of-law provisions. Nothing in this Section shall
-   prevent a party’s ability to bring cross-claims or counter-claims.
-
-9. Miscellaneous
-
-   This License represents the complete agreement concerning the subject matter
-   hereof. If any provision of this License is held to be unenforceable, such
-   provision shall be reformed only to the extent necessary to make it
-   enforceable. Any law or regulation which provides that the language of a
-   contract shall be construed against the drafter shall not be used to construe
-   this License against a Contributor.
-
-
-10. Versions of the License
-
-10.1. New Versions
-
-      Mozilla Foundation is the license steward. Except as provided in Section
-      10.3, no one other than the license steward has the right to modify or
-      publish new versions of this License. Each version will be given a
-      distinguishing version number.
-
-10.2. Effect of New Versions
-
-      You may distribute the Covered Software under the terms of the version of
-      the License under which You originally received the Covered Software, or
-      under the terms of any subsequent version published by the license
-      steward.
-
-10.3. Modified Versions
-
-      If you create software not governed by this License, and you want to
-      create a new license for such software, you may create and use a modified
-      version of this License if you rename the license and remove any
-      references to the name of the license steward (except to note that such
-      modified license differs from this License).
-
-10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
-      If You choose to distribute Source Code Form that is Incompatible With
-      Secondary Licenses under the terms of this version of the License, the
-      notice described in Exhibit B of this License must be attached.
-

 ## 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 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).
