Ready this for publication to the Python Package Index

- Makes a new console script available: `slim`
- Removes `requirements.txt` and replaces it with `pyproject.toml` which has both the dependencies and the package metadata
- Updates the instructions to demonstration installation from PyPI as well as how to continue local development
- Adds support for `--version` and version tracking
- Adds a `.gitignore`
- Removes potential [Dependency Confusion Vulnerabilities](https://medium.com/@alex.birsan/dependency-confusion-4a5d60fec610)
- Comments-out `tabulate` dependency; it doesn't appear to be used
- Removes `argparse` dependency; it's part of the standard library

 ### Setup Instructions
 
-1. Clone the repository
-   ```bash
-   git clone https://github.com/NASA-AMMOS/slim-cli.git
-   cd slim-cli
-   ```
-2. Install dependencies
-   ```bash
-   pip install -r requirements.txt
-   ```
+As the SLIM CLI is written in Python, you'll need Python 3.7 or later. Usually, you'll want to create a virtual environment in order to isolate the dependencies of SLIM from other Python-using applications. Install into that environment using `pip`:
+
+    pip install slim-cli
+
+This installs the latest SLIM CLI and its dependencies from the [Python Package Index](https://pypi.org/). The new console script `slim` is now ready for use. Confirm by running either:
+
+    slim --version
+    slim --help
+
+To upgrade:
+
+    pip install --upgrade slim-cli
+
+Or select a specific version, such as `X.Y.Z`:
+
+    pip install slim-cli==X.Y.Z
+

+### Local Development
+
+For local development of SLIM CLI, clone the GitHub repository, create a virtual environment, and then install the package in editable mode into it:
+```bash
+git clone --quiet https://github.com/NASA-AMMOS/slim-cli.git
+cd slim-cli
+python3 -m venv .venv
+source .venv/bin/activate
+pip install --editable .
+```
+
+The `slim` console-script is now ready in editable mode; changes you make to the source files under `src` are immediately reflected when run.
+
+To publish a new version of SLIM CLI to the Python Package Index, typically you'll update the `VERSION.txt` file; then do:
+```bash
+pip install build wheel twine
+python3 -m build .
+twine upload dist/*
+```
+
+(Note: this can and should eventually be automated with GitHub Actions.)
