+# Developer Scripts
+
+This repository houses opinionated scripts to simplify the development process. For CI workflows,
+it is recommended to exclusively use the `./Makefile`.
+
+## `source(styler_utils.R)`
+
+The `styler_utils.R` script is derived from `styler` and has been optimized for parallel execution.
+It utilizes `git diff`, `git status`, and identification of untracked files to determine which new
+files require styling.
+
+- `style_files()`: Automatically formats all modified files in parallel in a few seconds.
+- `style_entire_pkg()`: Restyles any file in the repository. Primarily used for chore pull requests
+to reset all files.
+
+## `source(develop_polars.R)`
+
+The `develop_polars.R` script provides opinionated presets for building polars during development,
+addressing 95% of use cases. It is unnecessary to run this script in a new R session, as all
+environment variables and loaded packages are reverted upon completion.
+
+- `load_polars()`: Invokes `extendr::document()` with preset environment variables and loaded
+packages.
+- `build_polars()`: Initiates `R CMD install` with preset environment variables.
+- `check_polars()`: Executes `devtools::check()` with preset environment variables and loaded
+packages. Additionally, it reuses the Rust cache and target files, even when the `check` command
+moves the working directory. The script deletes the temporary check directory afterward.
+- `run_all_examples_collect_errors()`: Calls `pkgload::run_example()` and captures all errors.
+Useful for running all examples at once without the need to manage restarts in case of errors.
+
+Feel free to modify the formatting and details according to your preferences and the specific needs
+of your project.
