-Automated FTPS/SFTP upload tool for practice exports
\ No newline at end of file
+Automated upload tool for practice exports. Uploads insurance PDFs and patient files to the correct FTP/SFTP servers for each practice, then archives what was sent.
+
+---
+
+## First-time setup
+
+1. Double-click **setup.bat** — this downloads WinSCP (needed for uploading)
+2. Set up your entity folders (see below)
+3. Double-click **run-all.bat** each day after running the PT STMT rename script
+
+---
+
+## Daily workflow
+
+1. Run the **PT STMT rename script** manually (as usual)
+2. Double-click **run-all.bat** to upload everything
+3. Check the window for any failures — failed files stay in place for retry
+
+---
+
+## Folder layout
+
+```
+run-all.bat                        <- double-click to run everything
+engine.ps1
+setup.bat
+WinSCP\                            <- created by setup.bat automatically
+Entities\
+  CAMBS\
+    entity.json                    <- server details for this entity
+    run.bat                        <- double-click to run just CAMBS
+    Export1\
+      AJMAT\
+        practice.json              <- only needed if AJMAT has its own FTP login
+        20260629\                  <- today's insurance PDFs go here
+        Archive sent to FTP\       <- uploaded date folders move here
+        Patient\
+          Export\
+            PT STMT_20260629\      <- created by rename script
+            Archive Sent to FTP\   <- uploaded patient folders move here
+      CIIR\
+        ...
+  CONSensio\
+    entity.json
+    ...
+```
+
+---
+
+## Setting up a new entity
+
+1. Create a folder under `Entities\` with the entity name (e.g. `Entities\CAMBS\`)
+2. Copy `run.bat` into it
+3. Create `entity.json` in that folder — copy from `Entities\EXAMPLE\entity.json` and fill in:
+
+| Setting | What to put |
+|---------|------------|
+| `workflow` | `insurance` if no patient files, `insurance+patient` if both |
+| `ftps.host` | FTP server address |
+| `ftps.username` | FTP username (shared across all practices) |
+| `ftps.password` | FTP password |
+| `ftps.tls` | `true` for FTPS (secure), `false` for plain FTP |
+| `ftps.insurance_path` | Remote path for insurance PDFs — keep `{practice}` in it |
+| `ftps.pdf_path` | Remote path for PT STMT PDFs — keep `{practice}` in it |
+| `sftp.host` | SFTP server (only needed if workflow is `insurance+patient`) |
+| `sftp.username` | SFTP username |
+| `sftp.password` | SFTP password |
+| `sftp.patient_path` | Remote path for patient files — keep `{practice}` in it |
+
+4. Create the `Export1\` folder and a subfolder for each practice inside the entity folder
+
+---
+
+## Setting up a practice with its own FTP login
+
+If one practice has its own FTP username/password (different from the entity default):
+
+1. Create a `practice.json` file inside that practice's folder
+2. Copy from `Entities\EXAMPLE\Export1\PRACTICE_NAME\practice.json`
+3. Fill in only the username and password that differ — everything else comes from entity.json
+
+---
+
+## Something went wrong?
+
+- **Files failed to upload** — they stay in the date folder. Fix the issue and run again.
+- **A date folder is still there after running** — one or more files failed. Check the output window.
+- **WinSCP error on startup** — run `setup.bat` again to re-download WinSCP.
