+# Consuming
+
+Consuming topics can be done by right clicking a topic in the explorer or from the command palette.  Some things to note about consuming:
+
+* UTF-8 encoded keys and values only. If data is encoded differently, it will not be pretty.
+* One consumer group is created per topic (may change in the future to just have one for the extension).
+
+Consumers are based on virtual documents, available in the VS Code extension API. A consumer will keep running even if you close the document in the editor. You should make sure to close the consumer explicitly, either via the command palette, the status bar element or the start/stop action button as well. The VS Code API does not support detecting if a virtual document is closed immediately. Instead, the underlying virtual document is automatically closed after two minutes if the document is closed in the editor.
+
+You can configure start offset for new consumers in settings (earliest, latest).

+# Producing
+
+Producing can be done by creating a `.kafka` file. Write simple producers using the following format:
+
+```json
+PRODUCER keyed-message
+topic: my-topic
+key: mykeyq
+record content
+
+###
+
+PRODUCER non-keyed-json-message
+topic: json-events
+{
+    "type": "my_test_event"
+}
+```
+
+For actually producing a single record, click on the "Produce record" link above the PRODUCER line; for producing 10 records, click on "Produce record x 10".
+The log about produced messages is printed in the "Kafka Producer Log" Output view.
+
+Record content can be randomized by injecting mustache-like placeholders of [faker.js properties](https://github.com/Marak/faker.js#api-methods), like ``{{name.lastName}}`` or ``{{random.number}}``. Some randomized properties can be localized via the `kafka.producers.fakerjs.locale` setting.
