+# Deployment — Two Hugging Face Spaces
+
+This project uses **two separate Hugging Face Spaces** so the live app stays stable while you build changes for a new client.
+
+| Environment | Space | Git remote | Branch | URL |
+|-------------|-------|------------|--------|-----|
+| **Production** (current clients) | `coderuday21/satdetect` | `hf` | `production` | https://huggingface.co/spaces/coderuday21/satdetect |
+| **Development** (new client work) | `coderuday21/satdetect-dev` | `hf-dev` | `master` | https://huggingface.co/spaces/coderuday21/satdetect-dev |
+
+---
+
+## One-time setup: create the dev Space
+
+1. Open **https://huggingface.co/new-space**
+2. Set:
+   - **Owner:** `coderuday21`
+   - **Space name:** `satdetect-dev`
+   - **SDK:** Docker
+   - **Visibility:** Public (or Private if you prefer)
+3. Click **Create Space**.
+
+Then add the dev remote (once):
+
+```powershell
+cd change_detection_webapp
+git remote add hf-dev https://huggingface.co/spaces/coderuday21/satdetect-dev
+```
+
+If `hf-dev` already exists, update it:
+
+```powershell
+git remote set-url hf-dev https://huggingface.co/spaces/coderuday21/satdetect-dev
+```
+
+Push the current development code to the new Space:
+
+```powershell
+git push hf-dev master:main
+```
+
+Or run the helper script:
+
+```powershell
+.\scripts\push_hf_dev.ps1
+```
+
+---
+
+## Branch strategy
+
+```
+production  ──► hf (satdetect)         — live app (no login; direct to detection)
+master      ──► hf-dev (satdetect-dev) — new client experiments and upcoming changes
+```
+
+- **`production`** — tracks the stable live release (currently same as `master`, no login).
+- **`master`** — active development; push to the dev Space for testing before promoting to production.
+
+Work on new client features on `master`. When ready for the live app, merge into `production` and push to `hf`.
+
+---
+
+## Deploy commands
+
+### Production (live app — no login)
+
+```powershell
+git checkout production
+git merge master
+git push hf production:main
+```
+
+Or push `master` directly to production:
+
+```powershell
+git push hf master:main
+```
+
+Helper:
+
+```powershell
+.\scripts\push_hf_production.ps1
+```
+
+### Development (new client Space)
+
+After every change you want on the dev Space:
+
+```powershell
+git checkout master
+git push hf-dev master:main
+```
+
+Helper:
+
+```powershell
+.\scripts\push_hf_dev.ps1
+```
+
+---
+
+## GitHub (optional mirror)
+
+GitHub tracks `master` only:
+
+```powershell
+git push origin master
+```
+
+You can add a `production` branch on GitHub too:
+
+```powershell
+git push origin production
+```
+
+---
+
+## Environment variables (both Spaces)
+
+Set these in each Space’s **Settings → Repository secrets / Variables** if needed:
+
+| Variable | Purpose |
+|----------|---------|
+| `SECRET_KEY` | Optional legacy JWT setting (login disabled) |
+| `DATABASE_URL` | PostgreSQL instead of SQLite (optional) |
+| `SMTP_USER` / `SMTP_PASS` | Email notifications via Gmail SMTP |
+| `EMAIL_API_URL` | Custom email API (default in code) |
+
+Dev Space can omit `SECRET_KEY` (login is disabled on both Spaces).
+
+---
+
+## Quick reference
+
+```powershell
+# Daily work (new client)
+git checkout master
+# ... edit code ...
+git add .
+git commit -m "Your message"
+git push hf-dev master:main
+
+# Update live app (only when ready)
+git checkout production
+git merge master          # or cherry-pick specific commits
+git push hf production:main
+git checkout master
+```

 ## First run
 
 - The SQLite DB and `data/` (overlay images) are created automatically on first use.
-- Register a new account from the welcome screen, then sign in.
 - Upload **Before** and **After** images, choose a method, and click **Run detection**.
 - Results appear below; runs are saved in **History**.
