## Issue Addressed
Related to #3672
## Proposed Changes
- Added a guide to run a node. Mainly, copy and paste from 'Merge Migration' and 'Checkpoint Sync'.
- Ranked it high in ToC:
- Introduction
- Installation
- Run a Node
- Become a Validator
...
- Hid 'Merge Migration' in ToC.
## Additional Info
- Should I add/rephrase/delete something?
- Now there is some redundancy:
- 'Run a node' and 'Checkpoint Sync' contain similar information.
- Same for 'Run a node' and 'Become a Validator'.
