+#### Available Tags
+- `latest` - Latest stable release
+- `v0.1.0`, `v0.2.0`, etc. - Specific version tags
+- `main` - Latest development build from main branch
+
+```bash
+# Pull the latest image
+docker pull joshrotenberg/redisctl:latest
+
+# Or pull a specific version
+docker pull joshrotenberg/redisctl:v0.1.0
+
+# Run a command directly
+docker run --rm joshrotenberg/redisctl:latest --help
