+# Hiddencode Project
+
+This workspace contains a minimal implementation matching the provided specification:
+
+- `server`: Flask server + SQLite database that stores SHA and two codes (upload/download).
+- `client/Writer`: C# WinForms app to write codes for a target file.
+- `client/Reader`: C# WinForms app to scan a folder and read codes for files.
+
+Quick start (macOS / Ubuntu for server):
+
+1. Server
+
+```bash
+cd server
+python3 -m venv venv
+source venv/bin/activate
+pip install -r requirements.txt
+python db_init.py
+python app.py
+```
+
+Server listens on `http://0.0.0.0:5000` by default.
+
+2. Clients (Windows recommended, requires .NET 6+)
+
+Open `client/Writer/Writer.csproj` and `client/Reader/Reader.csproj` in Visual Studio or run:
+
+```powershell
+cd client/Writer
+dotnet run
+
+cd ../Reader
+dotnet run
+```
+
+Notes:
+- Server base URL is `http://localhost:5000` in the client code; change if needed.
+- The server stores entries in SQLite file `server/hiddencode.db` with fields: id, sha, upload_code, download_code, created_at.
