In Designer, you'll prepare the documents for the required signers.
You can manually position and configure anchors, which are used to indicate where the signer will apply signing elements - such as a signature, date, or checkbox - to the document. See Position Document Anchors and Manage Document Anchors.
If TrueSign is appropriately configured, you can apply auto anchors. These anchors are configured in the document before it's uploaded to TrueSign. They're automatically surfaced on the document in the appropriate location prior to the signing process. See Configure Auto Anchors to learn more.
