How to say "primer" in Japanese

• 手引書てびきしょCommon
  nounCovers 'primer' as a practical instructional book — a manual or guide for how to do or use something. Its nuance is hands-on reference rather than gentle first introduction, so it suits workbooks and guides more than beginner's introductions.

  Such manuals should be written in simpler language.
• 入門にゅうもんCommon
  nounCovers 'primer' as an introduction to a field of study — the first book or course for beginners. It stresses entry-level initiation into a subject, and is the natural word for things English speakers call 'an introduction to X'.

For the 'introductory textbook' sense, 入門 is the usual everyday choice, while 手引書 leans toward a practical handbook or guide; neither covers paint or priming senses.
