ok this is fine. in general no need to open a new PR, just push to the old one.

[sahildua2305]

@jreback It had conflicts with the base branch. How would you have merged it?

[jreback]

see the contributing docs here and how git works. you simply rebase and fix the conflicts.

[sahildua2305]

Ah! Okay.

Actually I tried to rebase on my branch and ran into issues (it included other commits as well), that's why had to close the old PR.

[jreback]

thanks!

[jreback]

try git rebase -i origin/master in the future

[sahildua2305]

Thanks :)
