+# Make ISO flow
+
+This is the main flow when a user creates an ISO from HISv3.
+
+The diagram below follows the current Go service in this repo. In short, HISv3 asks the DICOM ISO service for one study, the service takes the study from PACS, builds an ISO file, then returns that file back for download.

+
+## Brief explanation
+
+When the user clicks **Make ISO** in HISv3, HISv3 sends a request to the DICOM ISO service.
+
+The DICOM ISO service then asks PACS for the study data that matches the accession number. After the study files are received, the service prepares them into one ISO file.
+
+When the ISO file is ready, the service sends it back as a download response. From the user side, the process stays simple: click **Make ISO**, wait a moment, then download the ISO file.
+
+## Note
+
+This is the basic user-facing flow.
+It leaves out lower-level details so the diagram stays easy to read.
