I apologize for the lack of translated instructions in this main page, so I attempted to translate them with Google Translate and create a scrollable list (see "Notes and Credits" for more information) that will hopefully make this project more accessible.
Scratch 3.0, and Google Translate. Designed the custom interface within Scratch. I made a custom project to translate the choose a language text into the currently supported 60 languages and export/import that through Scratch Desktop. Sorry if anything is confusing or was not translated well; it's meant to support any language to/from Google Translate, though Google Translate doesn't always work the way I expect it to so there may be confusing instructions in many languages. If you are using another web-based translator to read these notes and credits, start the project by typing the name of the language to use, then click on the top left box to set a language to translate from, the lower left box to set a language to translate to, and the top right box to translate a word or phrase. The boxes with arrows in them are used to swap languages around, in case you want to try typing something from another language or find another use for it (on terms of programming I wanted to test something that might swap variables, and Google Translate has something similar). I attempted to make this project in one day though I didn't realize it would take me a couple of hours to get it working. After another project that experimented with Google Translate, I've spent time working on this one instead to see if I can design a user-friendly interface and make something potentially useful (online translation works sometimes). I hope to also release the project I used that translates something you type in one language to all the languages Google Translate supports, since that may be interesting to show as well, where you could say something like "cat" and have it listed off in multiple languages at once.
