* docs: add the repository to the localhost:3000 link
Fix two links on **[Create Pages](https://docusaurus.io/docs/en/next/tutorial-create-pages)**.
* docs: use the same start command on both pages
The start command in **[Scaffold the Site](https://docusaurus.io/docs/en/next/tutorial-create-new-site)** is "Run `npm start` or `yarn start.`" It will help new users to see the same start command again. A slightly different command will make new users think that something slightly different is happening.
* docs: change the ID of the new documentation page
The page ID "doc4" is already used by one of the downloaded pages, docs/exampledoc4.md, shown below:
```
---
id: doc4
title: Other Document
---
this is another document
```
* docs: removed docusaurus-tutorial/ from the links
* Make it clear where the `docs` folder is
It was not clear, to the beginner user—who this tutorial is for—where the `docs` folder was . The only reason I know this is because I'm a beginner user and I tried for too many minutes to find the `docs` folder inside the `website` folder. I had this assumption because the previous example is offered under the assumption that you're in the `website` folder.
Feel free to change the wording, I just want to make it clear where you should be looking, if you're new.
* Update tutorial-create-pages.md
