The general flow of a README:

• A section describing what the package does and why it's important (i.e. "what's in it for me" for the user)

• A section on how to install and use the package

• A section on common configuration options and methods

• A section on how to contribute or pointer to CONTRIBUTING.md, notes on the developer's build environment and potential portability problems.

• a brief explanation of any unusual top-level directories or files, or other hints for readers to find their way around the source;

Github-flavored markdown

Since most all of my projects are Github, you have have some neat markdown block extensions available:

[!CAUTION] [!IMPORTANT] [!NOTE] [!TIP] [!WARNING]

Use these to call out any semantic sections.

Reading level

I prefer a Fleisch-Kincaid reading level of 9th grade or below. Revise the README until it is below a 9th grade level.

Use scripts/flesch_kincaid.rb <filename> [branch] to check the grade level. If a branch is provided (typically main ), the script will show the improvement compared to that branch.

IMPORTANT: Code blocks in markdown are ignored by the analysis scripts and should NEVER be modified for readability purposes.

ESL audience

Many of the people reading a software project README are not native speakers of English.

Use scripts/vocabulary_profiler.rb <filename> [branch] to check what % of words are in the top 1000 most common in English. If a branch is provided (typically main ), the script will show the improvement compared to that branch. Aim to increase this percentage.

IMPORTANT: Code blocks in markdown are ignored by the analysis scripts and should NEVER be modified for readability purposes.

DO use active voice where possible. DON'T assume passive constructions are easy just because the words are simple. DO keep noun phrases short and direct. DON'T stack multiple modifiers before nouns ("the recently revised standardized testing protocol"). DO limit embedded clauses—one level of nesting is usually manageable. DON'T assume simple vocabulary guarantees comprehension; "The man who the dog that bit the cat chased ran away" uses basic words but is notoriously hard to parse. DO use conditionals sparingly, favoring simple "if/then" structures. DON'T rely heavily on mixed or inverted conditionals ("Had she known..."). DO make logical connections explicit with transition words (however, therefore, because). DON'T expect readers to infer relationships between ideas. DO spread information across multiple sentences when needed. DON'T pack too many new concepts into a single sentence. DO explain or gloss cultural references. DON'T assume shared background knowledge about idioms, historical events, or cultural touchstones.
