 For more flexibility the exporter also allows exporting metrics collected from a text file.
 
 To enable textfile metrics:
-1. Enable the collector with `-collector.textfile=true`
-2. Provide the directory to read files from with the `-collector.textfile.directory` flag

 Metrics collected from these files will be exposed directly alongside the other metrics without any additional processing.
 This means that it is the responsibility of the file creator to ensure the format is correct.
