+# Writing guidelines for PineCoders Web content
+
+## Terminology
+
+### Annotations
+Don't use the term *annotation*, as it most probably will be phased out. We use *function* for everything that was called an annotation, except for `study()` and `strategy()`, for which we use the term *declaration statement*.
+
+### Realtime
+Use *realtime* rather than *real time* or *real-time*.
+
+### Script
+*Script* is useful when referring to both *indicators* and *strategies*.
+
+### Study vs Indicator
+Use *indicator* whenever you can, except when referring to the `study()` declaration statement itself.
+
+Example:
+> The first line of an indicator should be the `study()` declaration statement.
+
+Note than *indicator* is understood to include only *studies*. Pine strategies should be referred to as *strategies*—not *indicators*.
+
+## Style
+
+### Bulleted or enumerated lists punctuation
+Capitalize the first word of each element.
+
+List elements use no ending punctuation when they are not a sentence. This also applies to the last element in the list.<br>
+Use an ending period on all list elements when they are sentences, or when the majority is.
+
+### Capitalization of titles
+We follow the TradingView standard of capitalizing only the **first word** of titles.
