Presentation: Start working on a new guide

### Overview
We need to make a presentation for how to _Start working on a new guide_ so that Community of Practice members know how to do it.

### Action Items
- [x] Copy existing presentation
- [x] Trim out what we don't need
- [x] Add whatever else we do need (listen to the recording)
- [x] publish to the Product community of practice
- [ ] Add other community of practice links after verifying that they are properly representative of the tasks
