[lgalabru]

When starting a new language, we want to follow the following structure:

• Setup CI
  • Linting
  • Unit tests
  • End to end test using harness / interop
    -example directory, exposing one simple endpoint
• README:
  • Title
  • Badges (language, code-coverage)
  • Repo layout
  • Basic snippet of code using charge intent
  • How to use the lib
  • How to use the example
  • Client compatibility matrix:
    • x402/exact,
    • x402/upto,
    • x402/batch-settlement,
    • mpp/charge/pull,
    • mpp/charge/push,
    • mpp/session,
    • mpp/subscription
  • Server compatibility matrix:
    • x402/exact,
    • x402/upto,
    • x402/batch-settlement,
    • mpp/charge/pull,
    • mpp/charge/push,
    • mpp/session,
    • mpp/subscription
  • Coding convention / skill used for best practices (php best practices, etc)
  • Solana Dependencies
• Source directory
  • Code coverage > 90%, reported
  • Methods/classes/structs documented for LSP / IDE auto-completion
