Added user-friendly installation instructions by admercs · Pull Request #2141 · PowerShell/PSScriptAnalyzer

The -Scope parameter should be specified for Install-Module to clarify where the module will be installed. Without it, PowerShell will attempt to install to AllUsers scope which requires elevated permissions, potentially causing the command to fail for non-admin users.

Consider updating to:

Install-Module -Name PSScriptAnalyzer -Scope CurrentUser

This allows users to install the module without requiring administrator privileges.
