Hi, @XrandallX and welcome to the forum!

Can you please share the output of `qiime info`? It looks like the min/max length parameters were added to `extract-reads` in the [2018.11 release](https://forum.qiime2.org/t/qiime-2-2018-11-release-is-now-live/6879). You are viewing the 2020.2 release version of the docs, according to the URL you shared above.

I recommend viewing the documentation which corresponds to the version of QIIME 2 you are using. From `qiime info` I can see that I am using QIIME 2 release 2020.8:

```auto
➜ qiime info
System versions
Python version: 3.6.11
QIIME 2 release: 2020.8
QIIME 2 version: 2020.8.0
q2cli version: 2020.8.0

```

You can then use the drop down menu on the left side of the QIIME 2 docs to select the correct version:

I hope that helps! Let us know if you have any more questions 😄
