Context variables:

Document - variable of the Document (can be any document type) type. Stores the document which must be approved
Approvers - variable of the User type (Many-to-many link type). Stores the list of approvers

Script text:

var iniciator = (User)EleWise.ELMA.Security.Services.AuthenticationService.GetCurrentUser<EleWise.ELMA.Security.Models.IUser>(); // - the authenticated user initiates the approval
var harm = new ApprovementTaskGroup(); // - create a new approval task group 
harm.CreationAuthor = iniciator; // - identify the approval author 
harm.CreationDate = DateTime.Now; // - approval date 
harm.Subject = "Approve "+ context.Document.Name.ToString(); // - approval group name
harm.ExecutionDate = harm.ExecutionDate.AddDays(1); // - approval tasks due dates
harm.Status = ApprovalStatus.None; // - set status - rejected
harm.ApprovementList = new ApprovementList(); // - create a new approval sheet
harm.ExecutionType = ApprovementExecutionType.Parallel; // - identify the approval type
harm.Items.Add(new DocumentTaskItem{ Document = context.Document, Version = context.Document.Versions.FirstOrDefault() }); // - select a document and its version for approval 
harm.Save(); // - save the approval group 
var securityService = Locator.GetServiceNotNull<ISecurityService>();
//next, usres are loaded to the list of the document approvers, taking into account possible substitutions.
//if you don't need to take substitutions into account, the mechanism can be made simpler
