Google source files take the format taxonomy-with-ids.{locale}.txt
e.g. taxonomy-with-ids.en-GB.txt
Translated files take the format taxonomy-with-ids.{target-locale}.{source-locale}.txt
The .txt files first line is the title with version
e.g. # Google_Product_Taxonomy_Version: 2021-09-21
Main branch is used for google original files and completed translations.
To work on a translation, go to the correct branch, {target-locale}-{source-locale}-{version}.
E.g. cy-GB-en-GB-2021-09-21 for the Welsh (GB) translation from the English (GB) of google's 2021-09-21 version.
Create a branch if it doesn't already exist.
