+# ProjectStructure Configuration
+
+The repository reads user preferences from `config.json` in the ProjectStructure
+root (copied alongside helper batches when they are deployed to projects).
+
+## Keys
+
+| Key | Type | Meaning |
+| --- | --- | --- |
+| `dailyFormat` | bool | `true` → daily folders named `YYYY-MM-DD`; `false` → `daily_*` style. |
+| `structDir` | string | Absolute or relative path to the canonical ProjectStructure directory. Blank values default to the folder containing `config.json`. |
+| `projectsRoot` | string (optional) | Override for the root directory scanned by `UpgradeSeqBatches.ps1`. Defaults to the parent of `structDir`. |
+| `zipper` | bool | `true` → use 7‑Zip (if available); `false` → use Python’s built-in zipfile module. |
+| `compression` | int | Compression level `0-9` (0 = store only, 9 = max). Applies to both zipfile and 7‑Zip. |
+
+## Notes
+
+- `UpgradeSeqBatches.ps1` copies `config.json` and `ConfigLoader.ps1` to every
+  target folder so the helper `.bat` launchers can resolve script locations.
+- When `zipper` is `true`, the tool searches for `7z`/`7za` on `PATH`. If neither
+  is found it logs a warning and falls back to `zipfile`.
+- Leaving `structDir` empty is safe—the scripts fall back to the directory that
+  contains `config.json`.
