Thanks @davepagurek! Hi @xinemata, I will merge this if it looks good to you. I will also update the people page after we have more confirmed plan.

Hi @Qianqianye and @davepagurek, this looks great overall. A minor note I have is if we can break Processing Foundation into its own hyperlink?

For example, <a href="/people/">p5.js Contributors</a> and the <a href="https://processingfoundation.org/people">Processing Foundation</a>

@davepagurek @Qianqianye – actually, since the contributor list on the p5.js repo seems to be more up-to-date than the p5.js people page, maybe we should use this as the default link to attribute p5.js contributors?

Thanks @davepagurek and @xinemata. I updated the link to the p5.js website 'People' page for now after a conversation with @xinemata. Later, we will add the following to the people page:

• an instruction to add contributors to the list
• a section for p5.js website design contributors
