Thanks for sharing the final update @hangleang! I understand you want to meet the deadline before Devcon but it's better not to rush it. I'd suggest to remove the first paragraph, don't worry about the train ride and take your time after the conference to reflect and expand on the report :)

Yes, totally agree the first paragraph was not really related to the update, I just want to give a context to the reader
