Zowe Explorer is functional in a Theia environment. We should document how to include it in that environment. Perhaps this information could be provided in the docs folder and the README could link to it.
Work is done here for now: https://github.com/phaumer/vscode-extension-for-zowe/blob/theia-doc/docs/README-Theia.md
I created this PR https://github.com/zowe/vscode-extension-for-zowe/pull/359.
@Colin-Stone @MikeBauerCA do you want to review it?
Closing this one has the merge commit is not signed.
Created new PR: https://github.com/zowe/vscode-extension-for-zowe/pull/360
This could very well be included in the GA 1.0 : )
Completed. Thanks Peter
Thanks @phaumer for adding the doc.
Should we link to the file from the main README.md?
Which one? The readme in docs or even the one at the top? Perhaps the owners of these files could do it?
@IgorCATech, @BrandonJenkins14, @JamesBauman
Is it possible to add a link on the top level readme file that directs people to https://github.com/zowe/vscode-extension-for-zowe/blob/master/docs/README-Theia.md
It could be as simple as updating the Tip on the first section of the Readme. : )

Please see #392
I quite fancied an image of Zowe Explorer in it's Theia outfit that could be clicked on.
