# Bitbucket Drone comes with built-in support for Bitbucket. To enable Bitbucket, you must specify the `DRONE_REMOTE` environment variable with the URI configuration string. This section describes the URI format for configuring the Bitbucket driver. The following is the standard URI connection scheme: ``` bitbucket://host[:port][?options] ``` The components of this string are: * `bitbucket://` required prefix to load the Bitbucket driver * `host` server address to connect to * `:port` optional. The default value is `:80` if not specified. * `?options` connection specific options This is an example connection string: ```bash DRONE_REMOTE="bitbucket://client_key=c0aaff74c060ff4a950d&client_secret=1ac1eae5ff1b490892f5546f837f306265032412" ``` ## Bitbucket options This section lists all connection options used in the connection string format. Connection options are pairs in the following form: `name=value`. The value is always case sensitive. Separate options with the ampersand (i.e. &) character: * `client_key` oauth client key for registered application * `client_secret` oauth client secret for registered application * `open=false` allows users to self-register. Defaults to false for security reasons. * `orgs=drone,docker` restricts access to these Bitbucket organizations. **Optional**
