Second person and first person

Address the reader as you

In general, address the reader of your documents using the second person instead of the first person: use you or your instead of we, our, or us. Assume that the reader is the person who's doing the tasks that you're documenting. Use the word user only to refer to the user of the software that your reader is developing.

Use first-person plural pronouns carefully

It's OK to use first-person plural pronouns (such as we, our, or us) to refer to the organization that's represented as the author of the document. However, ensure that the antecedent for the pronoun is clear.

Address your audience consistently

It's important to identify who the you is that you're addressing (a developer? a sysadmin? someone else?) and to be consistent about that. Make it clear to the reader who you expect them to be (sometimes with an explicit audience sentence near the beginning of the document).
