+Automatic Schema Updating
+========
+GitBucket uses H2 database to manage project and account data. GitBucket updates database schema automatically in the first run after the upgrading.
+
+To release a new version of GitBucket, add the version definition to the [servlet.AutoUpdate](https://github.com/takezoe/gitbucket/blob/master/src/main/scala/servlet/AutoUpdateListener.scala) at first.
+
+```scala
+object AutoUpdate {
+  ...
+  /**
+   * The history of versions. A head of this sequence is the current BitBucket version.
+   */
+  val versions = Seq(
+      Version(1, 0)
+  )
+  ...
+```
+
+Next, add a SQL file which updates database schema into [/src/main/resources/update/](https://github.com/takezoe/gitbucket/tree/master/src/main/resources/update) as ```MAJOR_MINOR.sql```.
+
+GitBucket stores the current version to ```GITBUCKET_HOME/version``` and checks it at start-up. If the stored version differs from the actual version, it executes differences of SQL files between the stored version and the actual version. And ```GITBUCKET_HOME/version``` is updated by the actual version.
+
+We can also add any Scala code for upgrade GitBucket which modifies ｒesources other than database. Override ```Version.update``` like below:
+
+```scala
+val versions = Seq(
+  new Version(1, 3){
+    override def update(conn: Connection): Unit = {
+      super.update(conn)
+      // Add any code here!
+    }
+  },
+  Version(1, 2),
+  Version(1, 1),
+  Version(1, 0)
+)
+```

+These values are saved when users have reopened or closed the issue.
+At the same time, store the fixed value(i.e. "Close" or "Reopen") to the ```CONTENT``` column.
+Therefore, this comment is not displayed, and not counted as a comment.

+#####commit
+This value is saved when users have pushed including the ```#issueId``` to the commit message.
+At the same time, store it to the ```CONTENT``` column with its commit id.
+This comment is displayed. But it can not be edited by all users, and also not counted as a comment.
+
+#####merge
+This value is saved when users have merged the pull request.
+At the same time, store the message to the ```CONTENT``` column.
+This comment is displayed. But it can not be edited by all users, and also not counted as a comment.
+
+#####delete_branch
+This value is saved when users have deleted the branch. Users can delete branch after merging pull request which is requested from the same repository.
+At the same time, store it to the ```CONTENT``` column with the deleted branch name.
+Therefore, this comment is not displayed, and not counted as a comment.
+
+#####refer
+This value is saved when other issue or issue comment contains reference to the issue like ```#issueId```.
+At the same time, store id and title of the referrer issue as ```id:title```.

+Directory Structure

+  * /repositories 
+    * /USER_NAME
+      * / REPO_NAME.git (substance of repository. GitServlet sees this directory)

+
+There are some ways to specify the data directory instead of the default location.
+
+1. Environment variable __GITBUCKET_HOME__
+2. System property __gitbucket.home__ (e.g. ```-Dgitbucket.home=PATH_TO_DATADIR```)
+3. Command line option for embedded Jetty (e.g. ```java -jar gitbucket.war --data=PATH_TO_DATADIR```)
+4. Context parameter __gitbucket.home__ in web.xml like below:

+How to run from the source tree
+========
+
+for Testers
+--------
+
+If you want to test GitBucket, input following command at the root directory of the source tree.
+
+```
+C:\gitbucket> sbt ~container: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:
+
+```
+C:\gitbucket> sbt
+...
+> container:start
+...
+> ~ ;copy-resources;aux-compile
+```
+
+Build war file
+--------
+
+To build war file, run the following command:
+
+```
+C:\gitbucket> sbt package
+```
+
+`gitbucket_2.11-x.x.x.war` is generated into `target/scala-2.11`.
+
+To build executable war file, run Ant at the top of the source tree. It generates executable `gitbucket.war` into `target/scala-2.11`. We release this war file as release artifact. Please note the current build.xml works on Windows only. Replace `sbt.bat` with `sbt.sh` in build.xml if you want to run it on Linux.

+Notification Email
+========
+
+GitBucket sends email to target users by enabling the notification email by an administrator.
+
+The timing of the notification are as follows:
+
+##### at the issue registration (new issue, new pull request)
+When a record is saved into the ```ISSUE``` table, GitBucket does the notification.
+
+##### at the comment registration
+Among the records in the ```ISSUE_COMMENT``` table, them to be counted as a comment (i.e. the record ```ACTION``` column value is "comment" or "close_comment" or "reopen_comment") are saved, GitBucket does the notification.
+
+##### at the status update (close, reopen, merge)
+When the ```CLOSED``` column value is updated, GitBucket does the notification.
+
+Notified users are as follows:
+
+* individual repository's owner
+* collaborators
+* participants
+
+However, the operation in person is excluded from the target.

+Mapping and Validation
+========
+GitBucket uses [scalatra-forms](https://github.com/takezoe/scalatra-forms) to validate request parameters and map them to the scala object. This is inspired by Play2 form mapping / validation.
+
+At first, define the mapping as following:
+
+```scala
+import jp.sf.amateras.scalatra.forms._
+
+case class RegisterForm(name: String, description: String)
+
+val form = mapping(
+  "name"        -> text(required, maxlength(40)),
+  "description" -> text()
+)(RegisterForm.apply)
+```
+
+The servlet have to mixed in ```jp.sf.amateras.scalatra.forms.ClientSideValidationFormSupport``` to validate request parameters and take mapped object. It validates request parameters before action. If any errors are detected, it throws an exception.
+
+```scala
+class RegisterServlet extends ScalatraServlet with ClientSideValidationFormSupport {
+  post("/register", form) { form: RegisterForm =>
+    ...
+  }
+}
+```
+
+In the view template, you can add client-side validation by adding ```validate="true"``` to your form. Error messages are set to ```span#error-<fieldname>```.
+
+```html
+<form method="POST" action="/register" validate="true">
+  Name: <input type="name" type="text">
+  <span class="error" id="error-name"></span>
+  <br/>
+  Description: <input type="description" type="text">
+  <span class="error" id="error-description"></span>
+  <br/>
+  <input type="submit" value="Register"/>
+</form>
+```
+
+Client-side validation calls ```<form-action>/validate``` to validate form contents. It returns a validation result as JSON. In this case, form action is ```/register```, so ```/register/validate``` is called before submitting a form. ```ClientSideValidationFormSupport``` adds this JSON API automatically.
+
+For Ajax request, you have to use '''ajaxGet''' or '''ajaxPost''' to define action. It almost same as '''get''' or '''post'''. You can implement actions which handle Ajax request as same as normal actions.
+Small difference is they return validation errors as JSON.
+
+```scala
+ajaxPost("/register", form){ form =>
+  ...
+}
+```
+
+You can call these actions using jQuery as below:
+
+```javascript
+$('#register').click(function(e){
+  $.ajax($(this).attr('action'), {
+    type: 'POST',
+    data: {
+      name: $('#name').val(),
+      mail: $('#mail').val()
+    }
+  })
+  .done(function(data){
+    $('#result').text('Registered!');
+  })
+  .fail(function(data, status){
+    displayErrors($.parseJSON(data.responseText));
+  });
+});
+```
