+### Linting
+
+By default, the pipeline will run [fq lint](https://github.com/stjude-rust-labs/fq) on all input FASTQ files, both at the start of preprocessing and after each preprocessing step that manipulates FASTQ files. If errors are found, and error will be reported and the workflow will stop.
+
+The `extra_fqlint_args` parameter can be manipulated to disable [any validator](https://github.com/stjude-rust-labs/fq?tab=readme-ov-file#validators) from `fq` you wish. For example, we have found that checks on the names of paired reads are prone to failure, so that check is disabled by default (setting `extra_fqlint_args` to `--disable-validator P001`).
+
 ### Strandedness Prediction
 
 If you set the strandedness value to `auto`, the pipeline will sub-sample the input FastQ files to 1 million reads, use Salmon Quant to automatically infer the strandedness, and then propagate this information through the rest of the pipeline. This behavior is controlled by the `--stranded_threshold` and `--unstranded_threshold` parameters, which are set to 0.8 and 0.1 by default, respectively. This means:
