This needs a little work but should be good to go once the items above are addressed.

• There's a few places where the old language is just vague or unnecessarily long. We should fix this. I've marked them and provided suggestions, but there may be more. Please look at the original article and try to simplify it as much as possible, anywhere you can.

• Read up on INIT_SPACE https://www.anchor-lang.com/docs/space#the-init-space-macro

Also for "Before we begin, install Anchor by" - just link to 'local-setup.md' file instead, see CONTRIBUTING.md on how to make links.

I've made the changes and also went through the article once more to find and simplify some parts.

I did the editing for this one. Let me know if anything is left.

A few small suggestions to the old writing, plus some small tweaks - if you make them we can get this in today!

Formatting above looks odd, see CONTRIUBUTING.md

[SAMAD101]

I think it only appears like this in the diff window. I checked locally and on my github branch, its appears to be properly formatted there.

[mikemaccana]

I bet it's using a mix of tabs and spaces, and your local branch probably has some value set for tabs (2 spaces, 4 spaces, 8 spaces) that differs from what github uses. So yes it's a prob - please do fix it!

[SAMAD101]

Can you show/tell me whats exactly out of place here, I didn't touch this part and it seems like it is formatted like everything Rust part in the file. Also used rustfmt as instructed in CONTRIBUTING.md, nothing changes.

[mikemaccana]

Pardon the wait, we have a 24 person training course with new material then Rustconf then Breakpoint. See comments above.
