The new home of the support instead of Jira servicedesk is https://support.storj.io
Ok - but - where is the realy normal storjnode install link? There are only links for special questions. This is nothing for real new storjinglis.
All normal documentation on https://documentation.storj.io
Maybee a link to this site should be there.
The link you are asking for is right under the one you linked, under the heading ¨Installation¨ you will find the SNO installation instructions: https://support.storj.io/hc/en-us/articles/360027985272-Installation-of-v3-storage-node
If you clicked on ¨Installation of storage node¨ you would get to these instructions.
