Read the Source
Phrase · Slang & Abbreviations
Definitions
A direct suggestion to inspect the actual implementation rather than relying on guesswork, docs, or assumptions. In open-source and library-heavy work, it is often the fastest path to truth.
In plain English: Look at the actual code to understand how something works.
Example: "The docs are vague, so just read the source and see what the serializer actually does."
