# Configurables:
# QMK_DISTRIB_DIR: The directory to install the QMK distribution to.
# UV_INSTALL_DIR: The directory to install `uv` to.
# SKIP_CLEAN: Skip cleaning the distribution directory.
# SKIP_UV: Skip installing `uv`.
# SKIP_QMK_CLI: Skip installing the QMK CLI.
# SKIP_QMK_TOOLCHAINS: Skip installing the QMK toolchains.
# SKIP_QMK_FLASHUTILS: Skip installing the QMK flashing utilities.
# Environment variables:
# YES: Assume "yes" for all prompts. (or: --yes)
# QMK_DISTRIB_DIR: The directory to install the QMK distribution to. (or: --qmk-distrib-dir=...)
# UV_INSTALL_DIR: The directory to install `uv` to. (or: --uv-install-dir=...)
# SKIP_CLEAN: Skip cleaning the distribution directory. (or: --skip-clean)
# SKIP_PACKAGE_MANAGER: Skip installing the necessary packages for the package manager. (or: --skip-package-manager)
# SKIP_UV: Skip installing `uv`. (or: --skip-uv)
# SKIP_QMK_CLI: Skip installing the QMK CLI. (or: --skip-qmk-cli)
# SKIP_QMK_TOOLCHAINS: Skip installing the QMK toolchains. (or: --skip-qmk-toolchains)
# SKIP_QMK_FLASHUTILS: Skip installing the QMK flashing utilities. (or: --skip-qmk-flashutils)
#
# Arguments above may be negated by prefixing with `--no-` instead (e.g. `--no-skip-clean`).

# Usage:
# curl -fsSL https://raw.githubusercontent.com/qmk/qmk_firmware/master/util/env-bootstrap.sh | sh
#
# An example which skips installing `uv`:
# Help:
# curl -fsSL https://raw.githubusercontent.com/qmk/qmk_firmware/master/util/env-bootstrap.sh | sh -s -- --help
#
# An example which skips installing `uv` using environment variables:
# curl -fsSL https://raw.githubusercontent.com/qmk/qmk_firmware/master/util/env-bootstrap.sh | SKIP_UV=1 sh
#
# ...or by using command line arguments:
# curl -fsSL https://raw.githubusercontent.com/qmk/qmk_firmware/master/util/env-bootstrap.sh | sh -s -- --skip-uv

# Any other configurable items listed above may be specified in the same way.
