 ### Installation
 TextMate by default will detect .go files and load [Jim Dovey's bundle](https://github.com/AlanQuatermain/go-tmbundle). This is a fork with additional improvements merged from around the community.
 
 Big changes from the default version:
-- all non-run go commands operate on the current directory instead of per file (thanks [tg](https://github.com/tg))
+- Support for goimports (thanks [fmccann](https://github.com/fmccann))
+- Support for golint (thanks [fmccann](https://github.com/fmccann))
+- Users can supply commands via ENV variables (TM\_GO\_DYNAMIC\_GOPATH, TM\_GO\_DYNAMIC\_PKG, TM\_GO\_DYNAMIC\_PKG\_PATH). The bundle will consult these commands if defined to dynamically change the gopath or package based on the current directory. (thanks [fmccann](https://github.com/fmccann))
+- all non-run go commands operate on the current directory instead of per file if the package is not defined dynamically. (thanks [tg](https://github.com/tg)).
 - run and build work on unsaved files (thanks [tg](https://github.com/tg))
 - added print, println, printf, and fprintf snippets (thanks [jish](https://github.com/jish))
 - bugfixes

 >Thanks be to lasersox and Infininight over at the [#textmate room on IRC](irc://irc.freenode.net/textmate) for all their help in cleaning up this here bundle, and for helping me to optimize my regex use in the language grammar.
 Thanks to Martin Kühl for his extensive additions to this project's snippets and commands. Also Infininight's work on updating the bundle to use the TextMate's new Ruby interface and Jeremy & Sylvain's work on supporting Go 1.0 has been invaluable. Their assistance and stewardship while I've been deep in the world of Objective-C is very much appreciated.
