 Installation
 --------
-GitBucket requires **Java8**. You have to install beforehand when it's not installed.
+GitBucket requires **Java8**. You have to install it if it is not already installed.
 
-1. Download latest **gitbucket.war** from [the release page](https://github.com/gitbucket/gitbucket/releases).
-2. Deploy it to the Servlet 3.0 container such as Tomcat 7.x, Jetty 8.x, GlassFish 3.x or higher.
-3. Access **http://[hostname]:[port]/gitbucket/** using your web browser and logged-in with **root** / **root**.
+1. Download the latest **gitbucket.war** from [the releases page](https://github.com/gitbucket/gitbucket/releases) and run it by `java -jar gitbucket.war`.
+2. Go to `http://[hostname]:8080/` and log in with **root** / **root**.
 
-or you can start GitBucket by `java -jar gitbucket.war` without servlet container. In this case, GitBucket URL is **http://[hostname]:8080/**. You can specify following options.
+You can specify following options:
 
-- --port=[NUMBER]
-- --prefix=[CONTEXTPATH]
-- --host=[HOSTNAME]
-- --gitbucket.home=[DATA_DIR]
+- `--port=[NUMBER]`
+- `--prefix=[CONTEXTPATH]`
+- `--host=[HOSTNAME]`
+- `--gitbucket.home=[DATA_DIR]`
+- `--temp_dir=[TEMP_DIR]`
 
-To upgrade GitBucket, only replace gitbucket.war after stop GitBucket. All GitBucket data is stored in HOME/.gitbucket. So if you want to back up GitBucket data, copy this directory to the other disk.
+`TEMP_DIR` is used as the [temporary directory for the jetty application context](https://www.eclipse.org/jetty/documentation/9.3.x/ref-temporary-directories.html). This is the directory into which the `gitbucket.war` file is unpacked, the source files are compiled, etc. If given this parameter **must** match the path of an existing directory or the application will quit reporting an error; if not given the path used will be a `tmp` directory inside the gitbucket home.
 
-About installation on Mac or Windows Server (with IIS), configuration of Apache or Nginx and also integration with other tools or services such as Jenkins or Slack, see [Wiki](https://github.com/gitbucket/gitbucket/wiki).
+You can also deploy `gitbucket.war` to a servlet container which supports Servlet 3.0 (like Jetty, Tomcat, JBoss, etc)
 
-Plug-ins
+For more information about installation on Mac or Windows Server (with IIS), or configuration of Apache or Nginx and also integration with other tools or services such as Jenkins or Slack, see [Wiki](https://github.com/gitbucket/gitbucket/wiki).
+
+To upgrade GitBucket, replace `gitbucket.war` with the new version, after stopping GitBucket. All GitBucket data is stored in `HOME/.gitbucket` by default. So if you want to back up GitBucket's data, copy this directory to the backup location.

 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.
+GitBucket updates database schema automatically using [Solidbase](https://github.com/gitbucket/solidbase) in the first run after the upgrading.
 
-To release a new version of GitBucket, add the version definition to the [gitbucket.core.servlet.AutoUpdate](https://github.com/gitbucket/gitbucket/blob/master/src/main/scala/gitbucket/core/servlet/AutoUpdate.scala) at first.
+To release a new version of GitBucket, add the version definition to the [gitbucket.core.GitBucketCoreModule](https://github.com/gitbucket/gitbucket/blob/master/src/main/scala/gitbucket/core/GitBucketCoreModule.scala) at first.
 
 ```scala
-object AutoUpdate {
-  ...
-  /**
-   * The history of versions. A head of this sequence is the current GitBucket version.
-   */
-  val versions = Seq(
-      Version(1, 0)
+object GitBucketCoreModule extends Module("gitbucket-core",
+  new Version("4.0.0",
+    new LiquibaseMigration("update/gitbucket-core_4.0.xml"),
+    new SqlMigration("update/gitbucket-core_4.0.sql")
+  ),
+  new Version("4.1.0"),
+  new Version("4.2.0",
+    new LiquibaseMigration("update/gitbucket-core_4.2.xml")
   )
-  ...
-```
-
-Next, add a SQL file which updates database schema into [/src/main/resources/update/](https://github.com/gitbucket/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)
 )
 ```
+
+Next, add a XML file which updates database schema into [/src/main/resources/update/](https://github.com/gitbucket/gitbucket/tree/master/src/main/resources/update) with a filenane defined in `GitBucketCoreModule`.
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<changeSet>
+    <addColumn tableName="REPOSITORY">
+        <column name="ENABLE_WIKI" type="boolean" nullable="false" defaultValueBoolean="true"/>
+        <column name="ENABLE_ISSUES" type="boolean" nullable="false" defaultValueBoolean="true"/>
+        <column name="EXTERNAL_WIKI_URL" type="varchar(200)" nullable="true"/>
+        <column name="EXTERNAL_ISSUES_URL" type="varchar(200)" nullable="true"/>
+    </addColumn>
+</changeSet>
+```
+
+Solidbase stores the current version to `VERSIONS` table and checks it at start-up. If the stored version differs from the actual version, it executes differences between the stored version and the actual version.
+
+We can add the SQL file instead of the XML file using `SqlMigration`. It try to load a SQL file from classpath as following order:
+
+1. Specified path (if specified)
+2. `${moduleId}_${version}_${database}.sql`
+3. `${moduleId}_${version}.sql`
+
+Also we can add any code by extending `Migration`:
+
+```scala
+object GitBucketCoreModule extends Module("gitbucket-core",
+  new Version("4.0.0", new Migration(){
+    override def migrate(moduleId: String, version: String, context: java.util.Map[String, String]): Unit = {
+      ...
+    }
+  })
+)
+```
+
+See more details [README of Solidbase](https://github.com/gitbucket/solidbase).
