  - 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.
  - You should also [notify the current Head of Translation](#notifying-translation) to ensure a fast response.

-4. The Translation Team will approve the locale PR (after corrections, if necessary), then merge it into `pokerogue-locales`.
-5. The Dev Team will approve your main PR for your feature, then merge it into PokéRogue's beta environment.
+3. Your locales should use the following format:
+  - File names should be in `kebab-case`. Example: `trainer-names.json`
+  - Key names should be in `camelCase`. Example: `aceTrainer`
+    - If you make use of i18next's inbuilt [context support](https://www.i18next.com/translation-function/context), you need to use `snake_case` for the context key. Example: `aceTrainer_male`

 [^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.

Inês Simões	1517e0512e	[UI/UX] [Feature] Save Management Tool (Rename/Delete Saves) (#5978 ) * Implement Name Run Feat Modified load session ui component, adding a submenu when selecting a 3 slot. This menu has 4 options: Load Game -> Behaves as before, allowing the player to continue progress from the last saved state in the slot. Rename Run -> Overlays a rename form, allowing the player to type a name for the run, checking for string validity, with the option to cancel or confirm (Rename). Delete Run -> Prompts user confirmation to delete save data, removing the current save slot from the users save data. Cancel -> Hides menu overlay. Modified game data to implement a function to accept and store runNameText to the users data. Modified run info ui component, to display the chosen name when viewing run information. Example: When loading the game, the user can choose the Load Game menu option, then select a save slot, prompting the menu, then choose "Rename Run" and type the name "Monotype Water Run" then confirm, thus being able to better organize their save files. Signed-off-by: Matheus Alves <matheus.r.noya.alves@tecnico.ulisboa.pt> Co-authored-by: Inês Simões <ines.p.simoes@tecnico.ulisboa.pt> * Implement Rename Input Design and Tests for Name Run Feat Created a test to verify Name Run Feature behaviour in the backend (rename_run.test.ts), checking possible errors and expected behaviours. Created a UiHandler RenameRunFormUiHandler (rename-run-ui-handler.ts), creating a frontend input overlay for the Name Run Feature. Signed-off-by: Matheus Alves <matheus.r.noya.alves@tecnico.ulisboa.pt> Co-authored-by: Inês Simões <ines.p.simoes@tecnico.ulisboa.pt> * Fixed formating and best practices issues: Rewrote renameSession to be more inline with other API call funtions, removed debugging comments and whitespaces.

Signed-off-by: Matheus Alves matheus.r.noya.alves@tecnico.ulisboa.pt Co-authored-by: Inês Simões ines.p.simoes@tecnico.ulisboa.pt * Implemented Default Name Logic Altered logic in save-slot-select-ui-handler.ts to support default naming of runs based on the run game mode with decideFallback function. In game-data.ts, to prevent inconsistent naming, added check for unfilled input, ignoring empty rename requests. Signed-off-by: Matheus Alves matheus.r.noya.alves@tecnico.ulisboa.pt Co-authored-by: Inês Simões ines.p.simoes@tecnico.ulisboa.pt * Replace fallback name logic: use first active challenge instead of game mode Previously used game mode as the fallback name, updated to use the first active challenge instead (e.g. Monogen or Mono Type), which better reflects the run's theme.
