+# Hugging Face + Supabase Deployment Guide
+
+This repo is configured to run as a single Docker Space on Hugging Face.
+
+## What You Need
+
+- A Hugging Face account
+- A Supabase project
+- Your Supabase PostgreSQL connection string
+
+## Step By Step
+
+1. Create a Supabase project.
+2. Open the database settings and copy the PostgreSQL connection string.
+3. Push this repository to GitHub.
+4. Create a new Hugging Face Space.
+5. Choose `Docker` as the Space SDK.
+6. Point the Space at this repository.
+7. Make sure the Space uses the root [Dockerfile](./Dockerfile).
+8. Add these Space secrets or variables:
+   - `ConnectionStrings__DefaultConnection`
+   - `JwtSettings__Key`
+   - `JwtSettings__Issuer`
+   - `JwtSettings__Audience`
+   - `PasswordReset__RecoveryCode`
+9. Set `ConnectionStrings__DefaultConnection` to your Supabase PostgreSQL connection string.
+10. Leave `WebApi__BaseUrl` unset unless you want to override the internal default.
+11. Deploy the Space.
+
+## What the Container Does
+
+- Starts the Web API on `127.0.0.1:5001`
+- Starts the Web App on `127.0.0.1:5000`
+- Uses Nginx on port `7860` as the public entrypoint
+- Proxies `/api/*` to the API
+- Proxies everything else to the Web App
+
+## Notes
+
+- The API now creates the schema on startup if the database is empty.
+- The model has been switched from SQL Server to PostgreSQL-friendly mappings.
+- If deployment fails, the first thing to check is the Supabase connection string and whether the database is reachable.
+
+## First Login
+
+1. Open the Hugging Face Space URL.
+2. Wait for the container to finish starting.
+3. Try the default demo accounts from the repository README.
+4. If login works, confirm that dashboard and task pages load normally.

+# TaskTrackingSystem
+
+This repo runs the Web API and Web App together inside one Docker container for Hugging Face Spaces.
+
+## Hosting Setup
+
+- Database: Supabase PostgreSQL
+- Public app: Hugging Face Space
+- API and Web App: same container, routed through Nginx
+
+## Local Notes
+
+- The app now expects PostgreSQL instead of SQL Server.
+- The API creates the schema on first startup with `EnsureCreatedAsync()`.
+- The Web App talks to the API at `http://127.0.0.1:5001/api/` by default inside the container.
+
+## Default Demo Accounts
+
+- `admin` / `P@ssw0rd123!`
+- `mgr01` / `P@ssw0rd123!`
+- `emp01` / `P@ssw0rd123!`
