In order to say that one thing is ‘based on’ another in Japanese, the expression に基（もと）づいて will be used. This is a combination of the 格助詞（かくじょし） (case marking particle) に, the う - Verb, 基（もと）づく ‘to originate from’, and the 接続助詞（せつぞくじょし） (conjunction particle) て. This expression regularly highlights some kind of judgement/conclusion that the speaker has made, using (A) as their base.
To use に基（もと）づいて, put the noun (or noun phrase) that you would like to identify as a ‘basis’ before に基（もと）づいて, and then express your judgment/conclusion in part (B) of the sentence.

• クライアントの指示（しじ）に基（もと）づいて、編集（へんしゅう）をしておきました。

• 以前（いぜん）成功（せいこう）した計画（けいかく）に基（もと）づいて、新（あたら）しい計画（けいかく）を立（た）てようと思（おも）っています。
  I am thinking of making a new plan based on the previous successful plan.

Alternatively, the past form of 基（もと）づく may be used when connected directly to a second noun. (A) に基（もと）づいた (B) directly expresses that (B) is based on (A).
