 Support
 =======
 
-[Lightbend] sponsors sbt and encourages contributions from the active community. Enterprises can adopt it for mission critical systems with confidence because Lightbend stands behind sbt with commercial support and services.
-
 For community support please [ask] on StackOverflow with the tag "sbt" (and the name of the sbt plugin(s) if any).
 
 - State the problem or question clearly and provide enough context. Code examples and `build.sbt` are often useful when appropriately edited.
 - There's also [Gitter sbt/sbt room][gitter], but Stackoverflow is recommended so others can benefit from the answers.
