+## Common Workflows
+
+### Text+Meta performance wrangling
+
+If you have a lot of pads, you might want to try the following to speed things
+up. This example is something we do at Varia. Firstly, you download all the
+pads text + metadata as the only formats. This is likely what you want when
+you're trying to work directly with the text. You can do that like so:
+
+```bash
+$ etherpump pull --text --meta
+```
+
+The key here is to get the `--meta` so that etherpump is able to read quickly
+skip it on the following run if there are no new revisions. So, in practice,
+you get a slower first run and faster following runs as more pads are skipped
+from actually doing a file system write to save the contents which we already
+have.

 ## Library API Example
 
 Etherpump can be used as a library.
