Thanks! Left a bit of feedback here and there.

[johansmitsnl]

@lukechu10 applied the suggested changes.

[lukechu10]

I just realized you made the changes to the 0.8 docs. Do you mind also making the to docs/next? You can still leave the changes in 0.8 if it's too much trouble to remove them.
Otherwise, everything looks good.

[johansmitsnl]

@lukechu10 done. Left the v0.8 additions because they are also valid for that version right?

[lukechu10]

Sorry for taking so long. I noticed a small issue with the indentation, but I didn't want to delay this PR further, so I took the liberty of committing it myself (hopefully that's okay with you).
