+
+This plugin provides a facilty for storing a retreiving more complex data than tags, for compromise documents and matches.
+
+### Payload
+
+```js
+import plg from 'compromise-payload'
+nlp.extend(plg)
+
+let doc = nlp('i saw John Lennon in Manchester, and Bob Dylan in Southhampton')
+
+// markup metadata
+doc.match('(john lennon|bob dylan)').addPayload({ instrument: 'guitar' })
+
+// add more
+doc.people().forEach(m => {
+  if (m.has('lennon')) {
+    m.addPayload({ height: `5'11` })
+  }
+  if (m.has('ringo')) {
+    m.addPayload({ height: `5'8` })
+  }
+})
+
+// retrieve specific payloads
+doc.match('john lennon').getPayloads()
+doc.match('bob dylabn').getPayloads()
+
+// retrieve them all
+doc.getPayloads()
+
+// inspect given payloads:
+doc.debug('payload')
+```
+
+You can also pass a callback into `.addPayload()`:
+
+```js
+let doc = nlp('i saw John Lennon, and john smith and bob dylan')
+doc.people().addPayload(m => {
+  return { lastName: m.terms().last().text() }
+})
+```
+
+You can remove all, or selected payloads with `.clearPayload()`:
+
+```js
+doc.match('bob .').clearPayloads()
+doc.getPayloads().length // now 2
+
+doc.clearPayloads()
+doc.getPayloads().length // now 0
+```
+
+### 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
+```
