Neal Richardson commented on ARROW-7654:
----------------------------------------

[~tlantz] circling back on this. Are you able to add some docs for this? If setting up a build environment is challenging, you can probably get away without that for a doc-only PR.

> High level description:
>  * As of [this commit|https://github.com/apache/arrow/commit/df54da211448b5202aa08ed2b245eb78cfd1e50c] support to supply a Schema to ConvertOptions in the csv module module was added (I'll add, extremely useful!). Marked as affected in at least 0.12.0 based on the commit history, as well as 0.15.1 (I cannot verify anything between but would assume it is true over the whole version range).
>  * As of 0.15.1 the [published documentation|https://arrow.apache.org/docs/python/generated/pyarrow.csv.ConvertOptions.html#pyarrow.csv.ConvertOptions] only explains that a dictionary from field name to DataType can be supplied.
> Minimal reproduction: N/A, see link.
