+= Getting support for Spring Boot
+
+== GitHub issues
+We choose not use GitHub issues for general usage questions and support, prefering to
+use issues solely for the tracking of bugs and enhancements. If you have a general
+usage question please do not open a GitHub issue, but use one of the other channels
+described below.
+
+If you are reporting a bug, please help to speed up problem diagnosis by providing as
+much information as possible. Ideally, that would include a small
+https://github.com/spring-projects/spring-boot-issues[sample project] that reproduces the
+problem.
+
+== Stack Overflow
+The Spring Boot community monitors the
+http://stackoverflow.com/tags/spring-boot[`spring-boot`] tag on Stack Overflow. Before
+asking a question, please familiar yourself with Stack Overflow's
+https://stackoverflow.com/help/how-to-ask[advice on how to ask a good question].
+
+== Gitter
+If you want to discuss something or have a question that isn't suited to Stack Overflow,
+the Spring Boot community chat in the
+https://gitter.im/spring-projects/spring-boot[#spring-boot room on Gitter].
+
+== Pivotal Open Source Software Support
+If you are interested in more dedicated support, Pivotal provides
+https://pivotal.io/support/oss[premium support] for Spring Boot.
