-### Limitations
-
-Payloads are saved by sentence number and term position, in one store that every document from the same `nlp` shares. That means:
-
-- **Removing a sentence breaks the payloads that come after it.** They move to the wrong sentence, and the last one can go missing. Add payloads after you remove sentences, or add them again. Changing words inside a sentence is fine.
-
-```js
-let doc = nlp('One is red. Two is blue. Three is green.')
-doc.match('(red|blue|green)').forEach(m => m.addPayload({ color: m.text() }))
-doc.remove('two is blue')
-doc.getPayloads().map(p => [p.match.text(), p.val.color])
-// [['red', 'red'], ['Three is green', 'blue']]
-```
-
-- **A new document can see payloads from an older one** at the same sentence and term positions. Call `.clearPayloads()` on a document when you are done with it.
-
-```js
-nlp('the red car').match('car').addPayload({ kind: 'vehicle' })
-nlp('a blue bike').getPayloads().length // 1, from the first document
-```
