We can create additional guide which is a little more simple but, then we will need to maintain two guides, which is not ideal.

The intention of the issue wasn't moving the guide. The intention is adding a very simple SDK example to the cloud quick start.

Let's undo this change.

I got few improvements from @marquisdepolis:

1. Rename similar sounding Bodo Platform SDK pages to explain what they are!

• now we have Platform SDK Quick Start and Platform SDK Guide
• we also agreed on removing docs/docs/installation_and_setup/platform_sdk.md as this is already in both Platform SDK Quick Start and Platform SDK Guide

2. Put bodo platform sdk left hand side as second suggestion"
   
   not sure about that as first I think user should also understood Platform in general.

3. How to run a piece of code on a piece of data on one's laptop

   • this will require feature in Bodo Platform, right now not supported

4. We should support reading in files from local environment

   • this also will require feature in Bodo Platform, right now not supported

5. Add reference on source to be github, s3, workspace etc -- show how. Change code to read from a public s3 bucket and does some work on it - in the example

   • looks like we don't have public S3/Github with examples right now

6. Change the search too to hide older pages:

• search is not showing older pages, when you type Bodo SDK it will first show all pages that have Bodo and SDK but also it will show all pages with only Bodo or SDK thats why we got so many results
