This wiki has moved!
The documentation for Spring XD is now managed in the main git repository.
To read the latest version online, browse to http://docs.spring.io/spring-xd/docs/current-SNAPSHOT/reference/html/
If you’d like to contribute to the documentation (even fixing a minor typo), just issue a regular PR against the main repository. The documentation sources are written in Asciidoc and reside here.
