Adding a software guide

Software pages guide someone from scratch to a working result. Read Editing the wiki first for GitHub steps and general rules.

## 1. Overview

Reads Nikon `.nd2` microscope files into Python. Code: [github.com/jimrybarski/nd2reader](https://github.com/jimrybarski/nd2reader).

## 2. Installation

1. Install the package:

   ```bash
   pip install nd2reader
   ```

## 3. Usage

1. Open a file and read the first frame:

   ```python
   from nd2reader import ND2Reader
   with ND2Reader("movie.nd2") as images:
       first = images[0]
   ```

## 4. Troubleshooting

- **<Error message>:** <cause and fix>.

2. Rules

1. Put every command in a fenced code block labelled with its language (bash, python, matlab) so readers can copy it.
2. Number installation and usage steps; one command per step.
3. Link to the code repository; keep code there instead of pasting it into the wiki.
4. A screenshot of the expected output or settings window is worth a thousand words.
5. Never include passwords, API keys, server addresses or account names. Point to where they are kept instead.
6. LLM assistants: include only supplied commands and versions or those checked against the repository’s own instructions.
