+### Repository Setup
+
+This project uses a **dual-repository workflow**:
+
+- **Primary repository:** Gitea instance at `git.hawt.cloud` (read-write)
+- **Mirror repository:** GitHub (read-only mirror)
+
+### Workflow Organization
+
+**Gitea Workflows (`.gitea/workflows/`):**
+- **`bump-and-release.yml`** - Manual version bumping workflow
+  - Runs `bump_version.py` to update version in `pyproject.toml`
+  - Commits changes and creates git tag
+  - Pushes to Gitea (main branch + tag)
+  - Triggered manually via workflow_dispatch with choice of patch/minor/major bump
+- **`release.yml`** - Automated release creation
+  - Triggered when version tags are pushed
+  - Runs tests, builds packages
+  - Creates Gitea release with artifacts
+- **`test.yml`** - Test suite execution
+- **`security.yml`** - Security scanning
+
+**GitHub Workflows (`.github/workflows/`):**
+- **`docker-release.yml`** - Builds and publishes Docker images
+- **`pypi-release.yml`** - Publishes packages to PyPI
+- These workflows are read-only (no git commits/pushes) and create artifacts only
+
+### Release Process
+
+1. Run manual bump workflow on Gitea: **Actions → Bump Version and Release**
+2. Select version bump type (patch/minor/major)
+3. Workflow commits version change and pushes tag to Gitea
+4. Tag push triggers `release.yml` on Gitea (creates release)
+5. GitHub mirror receives tag and triggers artifact builds (Docker, PyPI)
+
+### Version Management
+
+Use `bump_version.py` for version updates:
+```bash
+python bump_version.py patch    # 0.3.0 -> 0.3.1
+python bump_version.py minor    # 0.3.0 -> 0.4.0
+python bump_version.py major    # 0.3.0 -> 1.0.0
+```

+## Network Dependency
+
+**Note:** The application loads the Transformers.js library (v3.0.0) from `cdn.jsdelivr.net` for client-side embedding generation. This requires an active internet connection and sends requests to a third-party CDN. The application will function without internet if you only use the file upload features for pre-computed embeddings.
+
+## Quick Start
+
+### Installation
+
+**Option 1: Install with uv (recommended)**
+
+```bash
+# Install as a CLI tool (no need to clone the repo)
+uv tool install embeddingbuddy
+
+# Run the application
+embeddingbuddy serve
+```
+
+**Option 2: Install with pip/pipx**
+
+```bash
+# Install with pipx (isolated environment)
+pipx install embeddingbuddy
+
+# Or install with pip
+pip install embeddingbuddy
+
+# Run the application
+embeddingbuddy
+```
+
+**Option 3: Run with Docker**
+
+```bash
+# Pull and run the Docker image
+docker run -p 8050:8050 ghcr.io/godber/embedding-buddy:latest
+```
+
+The application will be available at <http://127.0.0.1:8050>
+
+### Using the Application
+
+1. **Open your browser** to <http://127.0.0.1:8050>
+2. **Upload your data**:
+   - Drag and drop an NDJSON file containing embeddings (see Data Format below)
+   - Optionally upload a second file with prompts to compare against documents
+3. **Choose visualization settings**:
+   - Select dimensionality reduction method (PCA, t-SNE, or UMAP)
+   - Choose 2D or 3D visualization
+   - Pick color coding (by category, subcategory, or tags)
+4. **Explore**:
+   - Click points to view full content
+   - Toggle prompt visibility
+   - Rotate and zoom 3D plots
