    Questions about the guides

    How to use this section and what to do when a step fails.

    For anyone running their own server: from the first Ubuntu setup to VPN, firewall and web servers. Commands are given in full so you can run them step by step.

    Yes. Each article starts from the basics and explains what every command does. Start with the initial server setup and SSH key access.

    Yes. They are written for stock Ubuntu, Debian and Windows Server and do not depend on where the server is hosted.

    Some guides include a script that installs everything with one command. Its full contents are shown in the article, so you can read it before running it.

    We add articles as the same questions come in from customers. Published material is updated when software versions change.

    Yes, write to support. If the question is a common one it goes into the plan — a good share of these articles started as customer tickets.

    Support can walk you through the steps. If the job is larger, it is covered by the server administration service from €79/month.

    Any VPS from €5.49/month will do — with a 5-hour test period to check it before you pay. Every command in the guides runs on it without limits.
