+## Terminology and user communication
+
+There are two main confusions when talking about knobs:
+
+### Whether it's zero-based or one-based
+
+Sometimes when an user reports: knobs 1 and 2 gets better performance, dev may get confuse whether he means the knobs 1 and 2 literally, or the 1st and 2nd knobs (knobs 0 and 1).
+
+Debug knobs are **zero-based**, which means:
+* The first knob is the knob(0) (or knob0 henceforth), and the last one is the 15 (knob15, likewise)
+* You can talk: "knob0 is enabled/disabled", "In this video i was using only knobs 0 and 2", etc.
+
+### Whether one is talking about the knob itself or about the entire parameter value (which represents all knobs)
+
+Sometimes when an user reports: knob 3 results, it's unclear whether he's referring to knob setting with value 3 (which means both knob 0 and 1 are enabled), or to knob(3) specifically.
+Whenever you're instructing tests or reporting results, be precise about whether one you're talking to avoid confusion:
+
+* Setting based terminology
+
+Use the word in PLURAL (knobs), without mentioning which one, to refer to the setting, aka multiple knobs at once:
+Examples:
+- **knobs=0**: no knobs enabled
+- **knobs=1**: knob0 enabled, others disabled
+- **knobs=2**: knob1 enabled, others disabled
+- **knobs=3**: knobs 0 and 1 enabled, others disabled
+...
+
+* Knob based terminology
+
+Use the word in SINGULAR (knob), or in plural but referring which ones, when meaning multiple knobs at once:
+Examples:
+- **knob0**: knob 0 enabled, others disabled
+- **knob1**: knob 1 enabled, others disabled
+- **knobs 0 and 1**: knobs 0 and 1 enabled, others disabled
+...
+
