 # Linting & Formatting
 
-Writing clean, readable code is important, and linters and formatters are an integral part of ensuring code quality and readability.
+Writing clean, readable code is important, and linters and formatters are an integral part of ensuring code quality and readability. \
 It is for this reason we are using [Biome](https://biomejs.dev), an opinionated linter/formatter (akin to Prettier) with a heavy focus on speed and performance.
 
 ### Installation
-You probably installed Biome already without noticing it - it's included inside `package.json` and should've been downloaded when you ran `pnpm install` after cloning the repo. If you haven't done that yet, go do it.
+You probably installed Biome already without noticing it - it's included inside `package.json` and should've been downloaded when you ran `pnpm install` after cloning the repo. If you haven't done that yet, go do that first.
 
 # Using Biome
 
-For the most part, Biome attempts to stay "out of your hair", letting you write code while enforcing a consistent formatting standard and only notifying for errors it can't automatically fix.\
+For the most part, Biome attempts to stay "out of your hair", letting you write code while enforcing a consistent formatting standard and only notifying for errors it can't automatically fix. \
 On the other hand, if Biome complains about a piece of code, **there's probably a good reason why**. Disable comments should be used sparingly or when readabilty demands it - your first instinct should be to fix the code in question, not disable the rule.
 
 ## Editor Integration
 Biome has integration with many popular code editors. See [these](https://biomejs.dev/guides/editors/first-party-extensions/) [pages](https://biomejs.dev/guides/editors/third-party-extensions/) for information about enabling Biome in your editor of choice.
 
 ## Automated Runs
-Generally speaking, most users shouldn't need to run Biome directly; in addition to editor integration, [pre-commit hook](../lefthook.yml) will periodically run Biome before each commit.
-You will **not** be able to push code with `error`-level linting problems - fix them beforehand.
+Generally speaking, most users shouldn't need to run Biome directly; in addition to editor integration, a [pre-commit hook](../lefthook.yml) will automatically format and lint all staged files before each commit.
 
-We also have a [Github Action](../.github/workflows/quality.yml) to verify code quality each time a PR is updated, preventing bad code from inadvertently making its way upstream.
+> ![WARNING]
+> You will **not** be able to commit code if any staged files contain `error`-level linting problems. \

+
+We also have a [Github Action](../.github/workflows/linting.yml) to verify code quality each time a PR is updated, preventing bad code from inadvertently making its way upstream. \
+These are effectively the same commands as run by Lefthook, merely on a project-wide scale.
 
 ## Running Biome via CLI
-If you want Biome to check your files manually, you can run it from the command line like so:
+To run you Biome on your files manually, you have 2 main options:
+1. Run the scripts included in `package.json` (`pnpm biome` and `pnpm biome:all`). \
+    These have sensible defaults for command-line options, but do not allow altering certain flags (as some cannot be specified twice in the same command)
 
-```sh
-pnpm exec biome check --[flags]
-```
+2. Execute the Biome executable manually from the command line like so:
+    ```sh
+    pnpm exec biome check --[flags]
+    ```
+    This allows customizing non-overridable flags like `--diagnostic-level` on a more granular level, but requires slightly more verbosity and specifying more options.
 
 A full list of flags and options can be found on [their website](https://biomejs.dev/reference/cli/), but here's a few useful ones to keep in mind:
 
-- `--write` will cause Biome to write all "safe" fixes and formatting changes directly to your files (rather than just complaining and doing nothing).
-- `--changed` and `--staged` will only perform checks on all changed or staged files respectively. Biome sources this info from the relevant version control system (in this case Git).
+- `--write` will cause Biome to write all "safe" fixes and formatting changes directly to your files (rather than just complaining and erroring out).
+- `--changed` and `--staged` will limit checking to all changed or staged files respectively. Biome sources this info from the relevant version control system (in this case `git`).
 - `diagnostic-level=XXX` will only show diagnostics with at least the given severity level (`info/warn/error`). Useful to only focus on errors causing a failed workflow run or similar.
 
 ## Linting Rules
 
-We primarily use Biome's [recommended ruleset](https://biomejs.dev/linter/rules/) for linting JS/TS, with some customizations to better suit our project's needs[^1].

+- Some rules are currently marked as warnings (`warn`) to allow for gradual refactoring without blocking development. **Do not write new code that triggers these rules!**

+When a new feature or enhancement requires adding a new locales key **without changing text in existing keys**, we have the following workflow with regards to localization:
 1. You (the developer) make a pull request to the main repository for your new feature.
 If this feature requires new text, the text should be integrated into the code with a new `i18next` key pointing to where you plan to add it into the locales repository.
 2. You then make another pull request — this time to the `pokerogue-locales` repository — adding a new entry with text for each key you added to your main PR.
-  - You must add the corresponding **English keys** while making the PR; the Translation Team can take care of the rest[^2].
-  - 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.
