 --------
 GitBucket requires **Java8**. You have to install beforehand when it's not 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 latest **gitbucket.war** from [the release page](https://github.com/gitbucket/gitbucket/releases) and run it by `java -jar gitbucket.war`.
+2. Access `http://[hostname]:8080/` and logged 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]`

-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.
+Of course, you can also deploy gitbucket.war to a servlet container which supports Servlet 3.0 (like Jetty, Tomcat, JBoss, etc)

 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).
