Thanks for helping translate. It's a big job. Your part should be fairly simple though. All you'll need to do is generate a new strings file, or update an existing one.

1. Copy en.yml to a new file in the locales directory named after the language.
   • Use the two-letter ISO_639-1 code.
   • The extension must be .yml; for example de.yml.
2. Change the toplevel key from :en to the language code as a symbol.
   • For example, :de or :es.
3. Translate each value without changing the file structure.
   • Quotes around the string are not necessary unless it contains a special character, such as :
4. Submit a PR with your new language!

It might be easiest to just do this in the GitHub UI if you don't already have your own fork & clone of the project.

Copying a file isn't very straightforward in the web UI. Instead, you'll need to copy the file contents to your clipboard, then create a new file and paste it back in. Nevertheless, once the file's created, it's quite easy to update this way.
