How to write a technical specification document

[Title] Write a Technical Specification Document

Reference

  1. https://stackoverflow.blog/2020/04/06/a-practical-guide-to-writing-technical-specs/
  2. https://www.industrialempathy.com/posts/design-docs-at-google/

A technical specification document outlines how you’re going to address a technical problem by designing and building a solution for it. It’s sometimes also referred to as a technical design document, a software design document, or an engineering design document. It’s often written by the engineer who will build the solution or be the point person during implementation, but for larger projects, it can be written by technical leads, project leads, or senior engineers. These documents show the engineer’s team and other stakeholders what the design, work involved, impact, and timeline of a feature, project, program, or service will be.

  2. Open Git Bash.
  3. Generate a GPG key pair. If you are not on version 2.1.17 or greater then
    1. gpg --default-new-key-algo rsa4096 --gen-key
  4. Enter your user ID information.
  5. Type a secure passphrase. This is a must.
