1. Introduction

Erlang/OTP accepts many pieces of user-contributed code, but the contribution process is not necessarily trivial. In this document, I (the author) will describe possible issues for contributing a piece of code to Erlang/OTP, and how the issues can be effectively solved, based on my experience of writing Erlang rand module.

This documentation is written for people who want to know

• how the practical tips about writing Erlang/OTP modules;
• how the OTP code is developed and released; and
• what to do for contributing their pieces of code to OTP.

This documentation is originally written for a presentation called Writing A New Erlang/OTP Module for Beginners to be held in March 2017, including the contents which are not necessarily suitable for the presentation.
