= Environment

JReleaser can configure some of its fields from external sources. This allows keeping a stable configuration file and only
update the external sources to produce a new release. Values may be read from a Java `.properties` file or from
environment variables, the file has precendence over the environment variables.

By default, the external properties file should be located at `~/.jreleaser/config.properties` however you may change
that location by setting/changing the value of the `JRELEASER_USER_HOME` environment variable or using the block
described next:
