Move Contributing Guidelines to Bottom of README

Hi, this is a first-timers-only issue. This means we've worked to make it more legible to folks who either haven't contributed to our codebase before, or even folks who haven't contributed to open source before.

If that's you, we're interested in helping you take the first step and can answer questions and help you out as you do. Note that we're especially interested in contributions from people from groups underrepresented in free and open source software!

We know that the process of creating a pull request is the biggest barrier for new contributors. This issue is for you 💝

If you have contributed before, consider leaving this one for someone new and looking through our general help wanted issues. Thanks!

🤔 What you will need to know.

Nothing. This issue is meant to welcome you to Open Source :) We are happy to walk you through the process.

📋 Step by Step

[ ] 🙋 Claim this issue: Claim the issue by commenting. If someone else has claimed it, ask if they've opened a pull request already and if they're stuck -- maybe you can help them solve a problem or move it along!

💡 Learn how to claim 🙋

Claiming an issue

Unless the issue is marked as reserved for someone, you can just say "I'd like to try this!" and then you've claimed it - no need to wait for someone to assign it to you. Just be sure you link your pull request (PR) to this issue so we can see where your solution is.

And open one early if possible - even before you've completed it with additional commits - and others can help you figure out any issues you may face.
[ ] 📝 Update the file README.md in the $REPO repository (press the little pen Icon) and edit the line as shown below.

 5. `npm install http-server -g && http-server` (this installs http-server globally and then runs it, next time you just need to do `http-server` to run it locally)

 ## Purpose

 The purpose of this software is to convert a photo taken from an "Infragram" multispectral camera using NDVI or another technique, then colorize that image. It can then be downloaded or forwarded to another web app.

 ## Pi and VR versions

 Two extra folders `/pi/` and `/vr/` are for different variants of the project, designed to be run on a [Raspberry Pi-based camera](https://publiclab.org/infragram-pi) (live-streaming video through the converter from the Pi camera) and for use with a VR headset with a Pi camera attached to the front. These are experimental but if major breaking changes are implemented in the main `index.html` file, we would like them to be ported over to these files as well, especially the `/pi/` version, so the interfaces look and work the same.

Please keep us updated

💬⏰ - We encourage contributors to be respectful to the community and provide an update within a week of claiming a first-timers-only issue. We're happy to keep it assigned to you as long as you need if you update us with a request for more time or help, but if we don't see any activity a week after you claim it we may reassign it to give someone else a chance. Thank you in advance!

If this happens to you, don't sweat it! Grab another open issue.

Is someone else already working on this?

🔗- We encourage contributors to link to the original issue in their pull request so all users can easily see if someone's already started on it.

👥- If someone seems stuck, offer them some help! Otherwise, take a look at some other issues you can help with. Thanks!
