 - Azure Resource Manager
 - Azure DevOps Services

+## Global Options
+
+These options apply to all commands unless stated otherwise:
+
+- `--query`, `-q` <jmespath> - Apply JMESPath filter before output rendering.
+- `--output`, `-o` <format> - Output format: `table|t|alignedtable|at|prettytable|pt|tsv`.
+- `--columns`, `-C` <definition> - Column selection for table outputs:
+	- `col1` - Select column (case-insensitive match), keep raw header label.
+	- `col1:` - Select column (case-insensitive match), use auto-generated header label.
+	- `col1: Label 1` - Select column (case-insensitive match), use custom header label.
+	- Prefix token with `=` for exact column-name match: `=col1`, `=col1:`, `=col1:Label`.
+	- Tokens are comma-separated and rendered in the specified order.
+- `--help`, `-h` - Show command help.
+
+Note: `rest --header` is a command-specific HTTP header option and is unrelated to `--columns`.
+

-# Packaging sk-az-tools
-
-## Build model
-
- Source lives in `src/` as TypeScript (`.ts`).
- Runtime package is compiled to `dist/` using `npm run build`.
- Public package entrypoints (`exports` and `bin`) point to `dist/**`.
-
-## Package surface
-
- `exports` defines what consumers can import.
- `files` controls what is shipped to npm.
- Current shipping content is `dist`, `README.md`, and `LICENSE`.
-
-## Development workflow
-
-Build once:
-
-```bash
-npm run build
-```
-
-Build in watch mode:
-
-```bash
-npm run build:watch
-```
-
-Smoke check CLI output:
-
-```bash
-node dist/cli.js --help
-```
-
-## Publish checklist
-
-1. Run `npm run build` and ensure TypeScript compiles without errors.
-2. Verify package content with `npm pack --dry-run`.
-3. Create artifact: `npm pack --pack-destination ./artifacts`.
-4. Optionally install the artifact locally and validate CLI/imports.
-
-## Tarball usage
-
-Create package tarball:
-
-```bash
-npm pack --pack-destination ./artifacts
-```
-
-Install from tarball:
-
-```bash
-npm install ./artifacts/@slawek/sk-az-tools-<version>.tgz
-```
