-
-The architecture and platform of Node.js used for `npm install`
-must be the same as the architecture and platform of Node.js used at runtime.
-See the [cross-platform](#cross-platform) section if this is not the case.
-
-When using npm v6 or earlier, the `npm install --unsafe-perm` flag must be used when installing as `root` or a `sudo` user.
-
-When using npm v7 or later, the user running `npm install` must own the directory it is run in.
-
-The `npm install --ignore-scripts=false` flag must be used when `npm` has been configured to ignore installation scripts.
-
-Check the output of running `npm install --verbose --foreground-scripts sharp` for useful error messages.
-
-## Apple M1
-
-Prebuilt sharp and libvips binaries have been provided for macOS on ARM64 since sharp v0.29.0.
-
-## Cross-platform
-
-At `npm install` time, prebuilt binaries are automatically selected for the
-current OS platform and CPU architecture, where available.
-
-The target platform and/or architecture can be manually selected using the following flags.
-
-```sh
-npm install --platform=... --arch=... --arm-version=... sharp
-```
-
-* `--platform`: one of `linux`, `darwin` or `win32`.
-* `--arch`: one of `x64`, `ia32`, `arm` or `arm64`.
-* `--arm-version`: one of `6`, `7` or `8` (`arm` defaults to `6`, `arm64` defaults to `8`).
-* `--libc`: one of `glibc` or `musl`. This option only works with platform `linux`, defaults to `glibc`
-* `--sharp-install-force`: skip version compatibility and Subresource Integrity checks.
-
-These values can also be set via environment variables,
-`npm_config_platform`, `npm_config_arch`, `npm_config_arm_version`, `npm_config_libc`
-and `SHARP_INSTALL_FORCE` respectively.
-
-For example, if the target machine has a 64-bit ARM CPU and is running Alpine Linux,
-use the following flags:
-
-```sh
-npm install --arch=arm64 --platform=linux --libc=musl sharp
-```
-
-If the current machine is Alpine Linux and the target machine is Debian Linux on x64 cpu,
-use the following flags:
-
-```sh
-npm install --arch=x64 --platform=linux --libc=glibc sharp
-```
-
-Multiple platforms and architectures can be supported within the same installation tree.
-The following example for macOS installs x64 binaries then adds (via a rebuild) arm64 binaries:
-
-```sh
-npm install --platform=darwin --arch=x64 sharp
-npm rebuild --platform=darwin --arch=arm64 sharp
