 ## Output format
 
+The end goals of this package is to standardize the raw outputs from EpiNow2 into samples and summaries tables, and to write those standardized outputs, along with relevant metadata, logs, etc. to a standard directory structure. Once in CFA's standard format, the outputs can be passed into a separate pipeline that handles post-processing (e.g. plotting, scoring, analysis) of Rt estimates from several different Rt estimation models.
+
 The nested partitioning structure of the outputs is designed to facilitate both automated processes and manual investigation: files are organized by job and task IDs, allowing for efficient file operations using glob patterns, while also maintaining a clear hierarchy that aids human users in navigating to specific results or logs. Files meant primarily for machine-readable consumption (i.e., draws, summaries, diagnostics) are structured together to make globbing easier. Files meant primarily for human investigation (i.e., logs, model fit object) are grouped together by task to facilitate manual workflows.
 In this workflow, task IDs correspond to location specific model runs (which are independent of one another) and the jobid refers to a unique model run and disease. For example, a production job should contain task IDs for each of the 50 states and the US, but a job submitted for testing or experimentation might contain a smaller number of tasks/locations.
