+# Apache Log4j Boot
+
+Log4j Boot is a collection of bootstrapping modules to get up and running with
+various Log4j components. These modules pull in all the necessary dependencies
+to use the various optional features in Log4j.
+
+Log4j Boot is just getting started. See [Log4j Boot epic on JIRA][boot-jira].
+
+## Planned Modules
+
+All modules in this list are assumed to be prefixed with `log4j-boot-`. For the
+dependency lists, the format is `groupId:artifactId` or just `artifactId` for
+dependencies in `org.apache.logging.log4j`. All modules listed after logback are
+implicitly dependent on log4j-boot-core. All modules depend on log4j-api.
