@hemant-kr-meena I believe this repo is no longer maintained. I am currently developing Laravel Valet Windows 3, so please do go check it out. It tries to achieve as much parity of the Mac version as possible.

In regards to this PR, I have already updated ngrok to v3.3.0 but as of today updated to 3.3.1, also I've changed the share command dramatically so that it no longer has hard-coded parameters but instead it just passes any given commands/options through to ngrok.

For further PRs please submit to my repo, thanks.

@cretueusebiu It might be an idea to add a note on the README saying that this repo isn't maintained, and maybe a link to my repo as an alternative?
