 2. Go to `http://[hostname]:8080/` and log in with ID: **root** / Pass: **root**.
 
-You can specify following options:
-
-- `--port=[NUMBER]`
-- `--prefix=[CONTEXTPATH]`
-- `--host=[HOSTNAME]`
-- `--gitbucket.home=[DATA_DIR]`
-- `--temp_dir=[TEMP_DIR]`
-- `--max_file_size=[MAX_FILE_SIZE]`
-
-`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.

-`MAX_FILE_SIZE` is the max file size for upload files.

 You can also deploy `gitbucket.war` to a servlet container which supports Servlet 3.0 (like Jetty, Tomcat, JBoss, etc)
