Greptile Summary

This PR dramatically simplifies the README.md file from a comprehensive 55-line documentation to a minimal 5-line version. The change removes all visual branding elements (logo, badges), security contact information, contribution guidelines, and detailed project introduction, keeping only the essential information: project title, brief description, and a link to the full documentation at https://infisical.com/docs/sdks/languages/go.

This appears to be part of a documentation consolidation strategy where the team is moving toward minimal READMEs that primarily redirect users to comprehensive online documentation. This approach reduces maintenance overhead by centralizing documentation updates on the website rather than maintaining duplicate information in multiple repository READMEs. The pattern is common in organizations managing multiple SDK repositories where they want to ensure users always access the most current documentation while standardizing the approach across all repositories.

The change maintains the core purpose of a README - explaining what the project is and where to find complete information - while eliminating elements that require regular synchronization across repositories like security contacts, contribution guidelines, and version badges.

Confidence score: 5/5

• This PR is extremely safe to merge with virtually no risk of causing any issues
• Score reflects that this is purely a documentation change that removes content rather than modifying functionality or adding complexity
• No files require special attention as this is a straightforward README simplification
