Set up a hosting server

Task:

- configure the hosting server. This part seems to have been done by a previous developer who didnt finish the job.
- on it to deploy and configure the code of the site engine and the stack specified at the link to github (screenshot and link below)
- connect the Netlify-cms admin panel (https://www.netlify.com/)
- add a couple of simple markdown elements to netlify: highlighting the background of the text. As well as the ability to paste from the clipboard not only text, but also images

Questions:

1. The hosting is generally set up (the previous developer said that he was going to do something with security, I dont know if its true or not)
2. Current code with githab raised
3. The design in general can be used as old, but you will need minor edits for a maximum of several hours.
4. admin question: is it possible to connect netlify, is it difficult to make your own admin panel, is it possible to simplify even more by setting up exports from Notion / Roam Research

Payment: first you do a small part, I understand that you are competent and then calmly pay.
