To use your domain for blogging, you need two things:
- A web hotel (Medium or greater)
- Blogging software
If you haven't got a web hotel already, see our different packages here: web hotel
Upgrading to web hotel is explained here: upgrades
When your web hotel is ready, you must install blogging software. There are several options, and a popular choice is WordPress. We have explained how to use that here: Wordpress
If this is too advanced for you, there are several websites that allow you to create a blog with them, e.g. blogger.com or wordpress.com
When you have created a blog on one of these web pages, you can create a www forwarding from your domain to the web address you get from the blogging website. You can read more about that here: www forwarding
