prefer active vs passive (passive adds cognitive noise)
one idea per sentence
no pronouns (this, that, you, we, rarely "it")
"you" best in side-bars "you might get an error if..."
no gender pronouns (he, she, they); prefer roles "the systems engineer"
avoid possessive (ESL)
avoid contractions (It's, hadn't)
avoid posessives (ESL, unique to English?) (Its)
