Suggestion: Make documentation part of the git repo

**Is your feature request related to a problem? Please describe.**
For example http://chainforge.ai/docs/getting_started/ currently fails to mention DEEPSEEK_API_KEY and TOGETHER_API_KEY - it would be great to help keeping the docs up to date via github.
Also feature additions / enhancements / changes could be submitted with relevant updates to the docs

**Describe the solution you'd like**
Move the source of the documentation to be part of the repo

Review the current documentation at chainforge.ai/docs/getting_started/ and inspect the repository to determine how the docs are currently sourced. Define where the documentation should live and how GitHub changes would update it. Done means the documentation source is part of the repository and can be maintained alongside feature changes.
