Poem

🐰
Hopping through docs, a new key in my paw,
The README now sparkles with version awe.
"WEBCAT_API_KEY"—don't forget,
For Docker runs, it's your best bet!
Secure and ready, the server will cheer,
As bunnies and coders draw ever near.

README.md (4)

47-48: Standardize Docker run examples and image tags.
All examples currently pull tmfrisinger/webcat:latest. For clarity and production stability, consider:

• Using the version-specific tag (2.1.0) instead of or alongside latest.
• Consistently ordering environment variables.
• Explicitly noting default values when omitted.
  This improves reproducibility and reduces drift between environments.

Also applies to: 49-50, 53-54, 56-57

---

73-74: Make optional variables formatting consistent.
You’ve marked WEBCAT_API_KEY as Required. Please apply the same bold styling to denote that SERPER_API_KEY is Optional for consistency:

- - `SERPER_API_KEY`: Your Serper API key (optional, enables premium search results)
+ - `SERPER_API_KEY`: **Optional** - Your Serper API key (enables premium search results)

---

79-80: Clarify secret management for API keys.
The new section explains how to generate WEBCAT_API_KEY but could benefit from a note on secure storage (e.g., .env files, Docker secrets, or cloud vaults) and a warning not to commit keys to source control.

---

82-88: Enhance code examples with context and security best practices.

• Use bash after the opening backticks for syntax highlighting.
• Remind users to load their environment variables (e.g., via source .env or export).
• Advise using a secret manager or vault for production deployments.

41-42: Verify version consistency and tag usage.
The README now references version 2.1.0 and the latest tag; ensure these align with your Dockerfile, CI/CD pipelines, and release notes. Consider linking to the changelog or using immutable tags (e.g., full semantic version) for reproducible deployments.
