+== Basic writing guidelines
+
+* Avoid the passive voice, use the active voice. Only use the passive voice as a last resort. Most of the time you can write with the active voice.
+* Make it easy to scan
+** Use helpful titles and headings
+** Lists
+** Tables
+* By default, use the second person imperative _You_, not third person, _The user_. +
+Talk _to_ your reader, not _about_ them.
+* Be consistent, use the same word to refer to a thing in different sentences.
+* Use the present tense, not the future. For example:
++
+> To create a Signer you +++<del>+++*will*+++</del>+++ need the private key.
+* Don’t use slang.
+* Don’t refer to programmatic names as words.
+* Don’t use Latin (e.g. and i.e.).
+* Avoid quotation marks except for actual quotes.
+* Avoid ambiguous words, like _may_. Use _might_ or _can_, depending on your intent, instead of _may_.
+* Avoid complex words, use simple words where possible.
+* Avoid using parentheses, except as labels.

 == Adding files to the collection
 
 When you create new files, you must add them to the `components/Starknet/modules/<module>/nav*.adoc` file so that the build system can render them in the table of contents.
