+- At first, See [FAQ](https://github.com/gitbucket/gitbucket/wiki/FAQ) and check issues whether there is a same question or request in the past.
+- If you can't find same question and report, send it to [gitter room](https://gitter.im/gitbucket/gitbucket) before raising an issue.
+- We can also support in Japaneses other than English at [gitter room for Japanese](https://gitter.im/gitbucket/gitbucket_ja).
+- Write an issue in English. At least, write subject in English.
+- First priority of GitBucket is easy installation and reproduce GitHub behavior, so we might reject if your request is against it.

-$ brew install gitbucket
-==> Downloading https://github.com/takezoe/gitbucket/releases/download/1.10/gitbucket.war
-######################################################################## 100.0%
-==> Caveats
-Note: When using launchctl the port will be 8080.
-
-To have launchd start gitbucket at login:
-    ln -sfv /usr/local/opt/gitbucket/*.plist ~/Library/LaunchAgents
-Then to load gitbucket now:
-    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.gitbucket.plist
-Or, if you don't want/need launchctl, you can just run:
-    java -jar /usr/local/opt/gitbucket/libexec/gitbucket.war

+Authentication in Controller
+========
+GitBucket provides many [authenticators](https://github.com/gitbucket/gitbucket/blob/master/src/main/scala/gitbucket/core/util/Authenticator.scala) to access controlling in the controller.
+
+For example, in the case of `RepositoryViwerController`,
+it references three authenticators: `ReadableUsersAuthenticator`, `ReferrerAuthenticator` and `CollaboratorsAuthenticator`.
+
+```scala
+class RepositoryViewerController extends RepositoryViewerControllerBase
+  with RepositoryService with AccountService with ActivityService with IssuesService with WebHookService with CommitsService
+  with ReadableUsersAuthenticator with ReferrerAuthenticator with CollaboratorsAuthenticator with PullRequestService with CommitStatusService
+  with WebHookPullRequestService with WebHookPullRequestReviewCommentService
+
+trait RepositoryViewerControllerBase extends ControllerBase {
+  self: RepositoryService with AccountService with ActivityService with IssuesService with WebHookService with CommitsService
+    with ReadableUsersAuthenticator with ReferrerAuthenticator with CollaboratorsAuthenticator with PullRequestService with CommitStatusService
+    with WebHookPullRequestService with WebHookPullRequestReviewCommentService =>
+
+  ...
+```
+
+Authenticators provides a method to add guard to actions in the controller:
+
+- `ReadableUsersAuthenticator` provides `readableUsersOnly` method
+- `ReferrerAuthenticator` provides `referrersOnly` method
+- `CollaboratorsAuthenticator` provides `collaboratorsOnly` method
+
+These methods are available in each actions as below:
+
+```scala
+// Allows only the repository owner (or manager for group repository) and administrators.
+get("/:owner/:repository/tree/*")(referrersOnly { repository =>
+  ...
+})
+
+// Allows only collaborators and administrators.
+get("/:owner/:repository/new/*")(collaboratorsOnly { repository =>
+  ...
+})
+
+// Allows only signed in users which can access the repository.
+post("/:owner/:repository/commit/:id/comment/new", commentForm)(readableUsersOnly { (form, repository) =>
+  ...
+})
+```
+
+Currently, GitBucket provides below authenticators:
+
+|Trait                     | Method          | Description                                                                          |

 How to run from the source tree
 ========
 
-for Testers
+Run for Development
 --------
 
 If you want to test GitBucket, input following command at the root directory of the source tree.
 
 ```
-C:\gitbucket> sbt ~container:start
+$ sbt ~jetty:start
 ```
 
 Then access to `http://localhost:8080/` by your browser. The default administrator account is `root` and password is `root`.
 
-for Developers
---------
-If you want to modify source code and confirm it, you can run GitBucket in auto reloading mode as following:
-
-Windows:
-
-```
-C:\gitbucket> sbt
-...
-> container:start
-...
-> ~ ;copy-resources;aux-compile
-```
-
-Linux:
-
-```
-~/gitbucket$ ./sbt.sh
-...
-> container:start
-...
-> ~ ;copy-resources;aux-compile
-```
+Source code modification is detected and reloaded automatically. You can modify logging configuration by editing `src/main/resources/logback-dev.xml`.
 
 Build war file
 --------
 
 To build war file, run the following command:
 
-Windows:
-
 ```
-C:\gitbucket> sbt package
-```
-
-Linux:
-
-```
-~/gitbucket$ ./sbt.sh package
+$ sbt package
 ```
 
 `gitbucket_2.11-x.x.x.war` is generated into `target/scala-2.11`.

+JRebel integration (optional)
+=============================
+
+[JRebel](http://zeroturnaround.com/software/jrebel/) is a JVM plugin that makes developing web apps much faster.
+JRebel is generally able to eliminate the need for the following slow "app restart" in sbt following a code change:
+
+```
+> jetty:start
+```
+
+While JRebel is not open source, it does reload your code faster than the `~;copy-resources;aux-compile` way of doing things using `sbt`.
+
+It's only used during development, and doesn't change your deployed app in any way.
+
+JRebel used to be free for Scala developers, but that changed recently, and now there's a cost associated with usage for Scala. There are trial plans and free non-commercial licenses available if you just want to try it out.
+
+----
+
+## 1. Get a JRebel license
+
+Sign up for a [usage plan](https://my.jrebel.com/). You will need to create an account.
+
+## 2. Download JRebel
+
+Download the most recent ["nosetup" JRebel zip](http://zeroturnaround.com/software/jrebel/download/prev-releases/).
+Next, unzip the downloaded file.
+
+## 3. Activate
+
+Follow the [instructions on the JRebel website](http://zeroturnaround.com/software/jrebel/download/prev-releases/) to activate your downloaded JRebel.
+
+You can use the default settings for all the configurations.
+
+You don't need to integrate with your IDE, since we're using sbt to do the servlet deployment.
+
+## 4. Tell jvm where JRebel is
+
+Fortunately, the gitbucket project is already set up to use JRebel.
+You only need to tell jvm where to find the jrebel jar.
+
+To do so, edit your shell resource file (usually `~/.bash_profile` on Mac, and `~/.bashrc` on Linux), and add the following line:
+
+```bash
+export JREBEL=/path/to/jrebel/jrebel.jar
+```
+
+For example, if you unzipped your JRebel download in your home directory, you whould use:
+
+```bash
+export JREBEL=~/jrebel/jrebel.jar
+```
+
+Now reload your shell:
+
+```
+$ source ~/.bash_profile # on Mac
+$ source ~/.bashrc       # on Linux
+```
+
+## 5. See it in action!
+
+Now you're ready to use JRebel with the gitbucket.
+When you run sbt as normal, you will see a long message from JRebel, indicating it has loaded.
+Here's an abbreviated version of what you will see:
+
+```
+$ ./sbt
+[info] Loading project definition from /git/gitbucket/project
+[info] Set current project to gitbucket (in build file:/git/gitbucket/)
+>
+```
+
+You will start the servlet container slightly differently now that you're using sbt.

+
+## 6. Limitations
+
+JRebel is nearly always able to eliminate the need to explicitly reload your container after a code change. However, if you change any of your routes patterns, there is nothing JRebel can do, you will have to run `jetty:start`.
