- Multi-backend support via aliases (API and DB)
- Config stored in ~/.openworkers/config.json
- Database migrations using sqlx (with checksums)
- Split enum migrations to fix PostgreSQL transaction issue

+# OpenWorkers CLI
+
+Command-line interface for managing OpenWorkers deployments.
+
+## Installation
+
+```bash
+cargo install --path .
+```
+
+## Configuration
+
+The CLI uses aliases to connect to different backends. Config is stored in `~/.openworkers/config.json`.
+
+### Alias Types
+
+- **API**: Connect via REST API (hosted or self-hosted)
+- **DB**: Direct PostgreSQL connection (for infra/migrations)
+
+### Managing Aliases
+
+```bash
+# Add API alias
+ow alias set cloud --api https://dash.openworkers.com/api/v1 --token <token>
+ow alias set local --api http://localhost:3000 --token dev
+
+# Add DB alias
+ow alias set infra --db postgres://user:pass@host/db
+
+# List aliases
+ow alias list
+
+# Set default
+ow alias set-default cloud
+
+# Remove alias
+ow alias rm old-alias
+```
+
+### Default Alias
+
+On first run, a `cloud` alias pointing to `https://dash.openworkers.com/api/v1` is created as default.
+
+## Commands
+
+### Database Operations
+
+Requires a `db` type alias.
+
+```bash
+# Run pending migrations
+ow --alias infra db migrate
+
+# Check migration status
+ow --alias infra db status
+```
+
+### Using Aliases
+
+```bash
+# Use default alias
+ow db status
+
+# Use specific alias
+ow --alias infra db migrate
+```
+
+## Config File Format
+
+```json
+{
+  "version": 1,
+  "default": "cloud",
+  "aliases": {
+    "cloud": {
+      "type": "api",
+      "url": "https://dash.openworkers.com/api/v1",
+      "token": "owk_xxx"
+    },
+    "infra": {
+      "type": "db",
+      "database_url": "postgres://user:pass@host/db"
+    }
+  }
+}
+```
+
+## Development
+
+```bash
+# Build
+cargo build
+
+# Run
+cargo run -- alias list
+cargo run -- --alias infra db status
+```
