You can add a new site directly in the database or inside the project by clicking "+" near the "Site" selector on the Information tab.

To create a site, click “Add" on the Site database page. When clicked, a window will appear in which you can enter the name of the site, its address, contact phone number, manager, access mode, and mark if the site is blacklisted. If, when creating a project on the Information tab, you specify a site that is in the black list, the system will show a warning about this.

2. On the next page — "Site Editing" — you can edit the data, if necessary, and also add additional contacts. 

After filling in, click “Save”, and the site will appear in the general list of sites. To edit the site, just click on its name on the main page of the database.
