 ## Notes
 
--   Only miniSEED version 3 is supported
+-   Only miniSEED version 3 is supported. Use [mseedconvert](https://github.com/EarthScope/mseedconvert) to convert between V2 and V3.
 -   Currently, only serialisation is supported. Deserialisation is planned
 -   The various compression options offered by miniSEED aren't currently supported
 
 ### Why not Streams
 
-I wish I could use streams for this. Unfortunately, miniSEED requires setting the body length in one of the headers. This means we can't start generating the response until we have all the data for the body.
-
-We could try and estimate the body length though. E.g. if you want to stream the result of a huge database query as miniSEED, you could first do a `SELECT COUNT(*) ...` before the actual query, and use that, plus the encoding size to estimate the length of the body, thereby allowing you to stream the generated miniSEED data. I may look into doing something like this in the future.
