We don't provide WordPress hosting, so for our own blog (https://aleyantprintsoftware.com/fr/blog/
) we just signed up for hosting directly with WordPress, and then you have two easy options:
1) Add a link in your navigation to the blog. You can see we did this in https://www.pressero.com/
2) Wordpress can publish its articles as RSS. You can add the RSS feed to your site in the skin's area.
