Click the “Text” posting option on your Tumblr dashboard to create a new post. To add the “Read More” link to a text post you already published, open the post in edit mode. Compose your post as you would normally. If you plan to add images to your text post, you can insert them now. Position your cursor at the point where you want to insert the link break, and then click the Insert Read More Break button in the posting window. The icon looks like a dotted line between two solid lines. Click “Post” or “Save Post” when done. The “Read More” link appears in the post on your main blog page and on your followers’ dashboards. Clicking the link opens the full post on a separate page.
