An open, collaboratively written book documenting the internals of the Erlang runtime system (ERTS) and the BEAM virtual machine. It is written in AsciiDoc and published as a PDF, a GitHub Pages site, and a printed first edition.

Use cases

  • learn how the BEAM virtual machine works
  • understand Erlang runtime system internals
  • study BEAM instruction set and scheduler design
  • prepare for contributing to the Erlang/OTP VM
  • find a reference on ERTS memory management and processes

When to choose

  • you want a deep, technical reference on Erlang/OTP VM internals
  • you are a systems programmer or VM engineer working with BEAM
  • you prefer free, community-maintained documentation with source available

When to avoid

  • you need a beginner tutorial on writing Erlang programs
  • you want guaranteed up-to-date coverage of the latest OTP release
  • you need formal documentation rather than a work-in-progress book
