-Things to note about `-import`:
+Keep the following in mind when using `-import`:
 
 - To throttle the import, use `-pps` to set the number of points per second to ingest. By default, pps is zero and `influx` does not throttle importing.
 - To import a file compressed with `gzip` (GNU zip), include the -compressed flag.
