You'll see a list of agencies. Click on the name of your agency.
Here you can edit the name, description, color, background image, featured image, and agency page links. After making a change, you can preview the updated page by clicking "Preview" in the box on the upper right.
To change the background image, first remove the existing image by hovering your cursor over the background image and clicking the X button.
Then click on "Add Image", and select or upload the image you want.
The agency page links should rarely need to be changed, but you can remove a link by hovering your cursor over the right side of the menu to find the - button.
You can add a new link by clicking the "Add link" button, where you'll be able to enter the link name and select the page that the link will go to (the page has to be already created). If you'd like to make major changes to your agency pages, please contact Trillium for support.
