 ## Changing English strings
 If you change an english string in a way that does not require editing other languages (such as fixing a typo that doesn't change the meaning), you'll need to also change the `[english]` copy of the string in each of the other language files too (for positive ci-checks later on). The sync-tool will do the hard work for you. Start it after you've made your change in the english file.
