Create the Site
Time to roll the sleeves up and get started!
First, you need to build a new Communication Site. To do this, sign in at www.office.com, find and click the icon to access SharePoint, then click Create Site.

From the panel that appears, choose Communication site:
If you’re not sure which design to choose, go with Topic. Follow the prompts to choose a Site name, check the address, and click Finish to create your site:
Congratulations! You’ve got a microsite! It should look like this:
For now, only you, as the creator, can access the microsite.
