Hi @mirkoperillo,

I was wondering if I can follow the same exercise as it is done by C#. (link: https://github.com/exercism/v3/blob/master/languages/csharp/exercises/concept/inheritance/.docs/instructions.md)

I think it will be good to have this consistency.

What are your thoughts?
TIA

[mirkoperillo]

Yes @himanshugoyal1065 absolutely

Hi @mirkoperillo,

How to run Prettier on the instructions pages? I wasn't able to find much about it. Can you please point me to some page where it is described?

Also, as @iHiD has added hacktober tag, can we have that for this issue as well?

TIA.

To run prettier from the command line/terminal, there are 2 scripts in the bin folder of the repo, format.cmd & format.sh for windows and posix respectively. From the root of the repo run bin/format.cmd or bin\format.cmd depending on you OS.

It can also be run from the PR directly by commenting with the text "/format".

@himanshugoyal1065 You don't actually need the hacktober tag for it to count against your hacktober count 🙂

@iHiD, now you know that I'm participating for the first time :D
