@jywarren @sagarpreet-chadha as discussed in the call I have added dist to gitignore.

[sagarpreet-chadha]

Oh cool! Sorry i missed the call .
So how do we plan to 'grunt build' the dist ?
Will the maintainer do that before releasing new version ? Thanks!

[ananyaarun]

According to me a developer can grunt build the dist files to run and test their changes locally (this has been added to readme)
And as you said perhaps the maintainer can do that before releasing a new version ?

[sagarpreet-chadha]

Okay great! @jywarren can we automate grunt build process prior to npm publish ? If yes, i would love to implement it if you can help :)

[jywarren]

I think it is possible. I put some notes here? publiclab/image-sequencer#773 (comment)
