A brief description of the layout:

• .gitignore varies per project, but all projects need to ignore bin directory.
• CHANGELOG.md contains auto-generated changelog information.
• README.md is a detailed description of the project.
• pkg places most of project business logic.
• test holds all tests.
• external for all external services i.e. feed data provider and notifier.

Notes

• Makefile MUST NOT change well-defined command semantics, see Makefile for details.
