   - For any feature pulled from the mainline Pokémon games (e.g. a Move or Ability implementation), it's best practice to include a source link for any added text.  
   [Poké Corpus](https://abcboy101.github.io/poke-corpus/) is a great resource for finding text from the mainline games; otherwise, a video/picture showing the text being displayed should suffice.

 [^2]: For those wondering, the reason for choosing English specifically is due to it being the master language set in Pontoon (the program used by the Translation Team to perform locale updates).
 If a key is present in any language _except_ the master language, it won't appear anywhere else in the translation tool, rendering missing English keys quite a hassle.
