-### Does this problem relate to file caching?
-
-The default behaviour of libvips is to cache input files, which can lead to `EBUSY` or `EPERM` errors on Windows.
-Use [`sharp.cache(false)`](https://sharp.pixelplumbing.com/api-utility#cache) to switch this feature off.
-
-- [ ] Adding `sharp.cache(false)` does not fix this problem.
-
-### Does this problem relate to images appearing to have been rotated by 90 degrees?
-
-Images that contain EXIF Orientation metadata are not auto-oriented. By default, EXIF metadata is removed.
-
-- To auto-orient pixel values use the parameter-less [`rotate()`](https://sharp.pixelplumbing.com/api-operation#rotate) operation.
-- To retain EXIF Orientation use [`keepExif()`](https://sharp.pixelplumbing.com/api-output#keepexif).
-
-- [ ] Using `rotate()` or `keepExif()` does not fix this problem.

-The typical use case for this high speed Node-API module
+The typical use case for this high speed Node.js module
 is to convert large images in common formats to
 smaller, web-friendly JPEG, PNG, WebP, GIF and AVIF images of varying dimensions.
 
-It can be used with all JavaScript runtimes
-that provide support for Node-API v9, including
-Node.js (^18.17.0 or >= 20.3.0), Deno and Bun.
-

+is downloaded via HTTPS, verified via Subresource Integrity
+and decompressed into `node_modules/sharp/vendor` during `npm install`.
+
+This provides support for the
+JPEG, PNG, WebP, AVIF (limited to 8-bit depth), TIFF, GIF and SVG (input) image formats.
+
+The following platforms have prebuilt libvips but not sharp:
+
+* Linux ARMv7 (glibc >= 2.28)
+* Linux ARMv6 (glibc >= 2.28)
+* Windows ARM64
+
+The following platforms require compilation of both libvips and sharp from source:
+
+* Linux x86
+* Linux ARMv7 (glibc <= 2.27, musl)
+* Linux ARMv6 (glibc <= 2.27, musl)
+* Linux PowerPC
+* FreeBSD
+* OpenBSD
+
+## Common problems
+
+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
+```
+
+## Custom libvips
+
+To use a custom, globally-installed version of libvips instead of the provided binaries,
+make sure it is at least the version listed under `config.libvips` in the `package.json` file
+and that it can be located using `pkg-config --modversion vips-cpp`.
+
+For help compiling libvips and its dependencies, please see
+[building libvips from source](https://www.libvips.org/install.html#building-libvips-from-source).
+
+The use of a globally-installed libvips is unsupported on Windows
+and on macOS when running Node.js under Rosetta.
+
+## Building from source
+
+This module will be compiled from source at `npm install` time when:
+
+* a globally-installed libvips is detected (set the `SHARP_IGNORE_GLOBAL_LIBVIPS` environment variable to skip this),
+* prebuilt sharp binaries do not exist for the current platform, or
+* when the `npm install --build-from-source` flag is used.
+
+Building from source requires:
+
+* C++11 compiler
+* [node-gyp](https://github.com/nodejs/node-gyp#installation) and its dependencies
+
+## Custom prebuilt binaries
+
+This is an advanced approach that most people will not require.
+
+### Prebuilt sharp binaries
+
+To install the prebuilt sharp binaries from a custom URL,
+set the `sharp_binary_host` npm config option
+or the `npm_config_sharp_binary_host` environment variable.
+
+To install the prebuilt sharp binaries from a directory on the local filesystem,
+set the `sharp_local_prebuilds` npm config option
+or the `npm_config_sharp_local_prebuilds` environment variable.
+
+URL example:
+if `sharp_binary_host` is set to `https://hostname/path`
+and the sharp version is `1.2.3` then the resultant URL will be
+`https://hostname/path/v1.2.3/sharp-v1.2.3-napi-v5-platform-arch.tar.gz`.
+
+Filename example:
+if `sharp_local_prebuilds` is set to `/path`
+and the sharp version is `1.2.3` then the resultant filename will be
+`/path/sharp-v1.2.3-napi-v5-platform-arch.tar.gz`.
+
+### Prebuilt libvips binaries
+
+To install the prebuilt libvips binaries from a custom URL,
+set the `sharp_libvips_binary_host` npm config option
+or the `npm_config_sharp_libvips_binary_host` environment variable.
+
+To install the prebuilt libvips binaries from a directory on the local filesystem,
+set the `sharp_libvips_local_prebuilds` npm config option
+or the `npm_config_sharp_libvips_local_prebuilds` environment variable.
+
+The version subpath and filename are appended to these.
+
+URL example:
+if `sharp_libvips_binary_host` is set to `https://hostname/path`
+and the libvips version is `4.5.6` then the resultant URL will be
+`https://hostname/path/v4.5.6/libvips-4.5.6-platform-arch.tar.br`.
+
+Filename example:
+if `sharp_libvips_local_prebuilds` is set to `/path`
+and the libvips version is `4.5.6` then the resultant filename will be
+`/path/v4.5.6/libvips-4.5.6-platform-arch.tar.br`.
+
+See the Chinese mirror below for a further example.
+
+If these binaries are modified, new integrity hashes can be provided
+at install time via `npm_package_config_integrity_platform_arch`
+environment variables, for example set
+`npm_package_config_integrity_linux_x64` to `sha512-abc...`.
+
+The integrity hash of a file can be generated via:
+```sh
+sha512sum libvips-x.y.z-platform-arch.tar.br | cut -f1 -d' ' | xxd -r -p | base64 -w 0
+```
+
+## Chinese mirror
+
+A mirror site based in China, provided by Alibaba, contains binaries for both sharp and libvips.
+
+To use this either set the following configuration:
+
+```sh
+npm config set sharp_binary_host "https://npmmirror.com/mirrors/sharp"
+npm config set sharp_libvips_binary_host "https://npmmirror.com/mirrors/sharp-libvips"
+npm install sharp
+```
+
+or set the following environment variables:
+
+```sh
+npm_config_sharp_binary_host="https://npmmirror.com/mirrors/sharp" \
+  npm_config_sharp_libvips_binary_host="https://npmmirror.com/mirrors/sharp-libvips" \
+  npm install sharp
+```
+
+## FreeBSD
+
+The `vips` package must be installed before `npm install` is run.
+
+```sh
+pkg install -y pkgconf vips
+```
+
+```sh
+cd /usr/ports/graphics/vips/ && make install clean
+```
+
+## Linux memory allocator
+
+The default memory allocator on most glibc-based Linux systems
+(e.g. Debian, Red Hat) is unsuitable for long-running, multi-threaded
+processes that involve lots of small memory allocations.
+
+For this reason, by default, sharp will limit the use of thread-based
+[concurrency](api-utility#concurrency) when the glibc allocator is
+detected at runtime.
+
+To help avoid fragmentation and improve performance on these systems,
+the use of an alternative memory allocator such as
+[jemalloc](https://github.com/jemalloc/jemalloc) is recommended.
+
+Those using musl-based Linux (e.g. Alpine) and non-Linux systems are
+unaffected.
+
+## AWS Lambda
+
+The `node_modules` directory of the
+[deployment package](https://docs.aws.amazon.com/lambda/latest/dg/nodejs-package.html)
+must include binaries for the Linux x64 platform.
+
+When building your deployment package on machines other than Linux x64 (glibc),
+run the following additional command after `npm install`:
+
+```sh
+npm install
+rm -rf node_modules/sharp
+SHARP_IGNORE_GLOBAL_LIBVIPS=1 npm install --arch=x64 --platform=linux --libc=glibc sharp
+```
+
+To get the best performance select the largest memory available.
+A 1536 MB function provides ~12x more CPU time than a 128 MB function.
+
+When integrating with AWS API Gateway, ensure it is configured with the relevant
+[binary media types](https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-payload-encodings.html).
+
+## Bundlers
+
+### webpack
+
+Ensure sharp is excluded from bundling via the
+[externals](https://webpack.js.org/configuration/externals/)
+configuration.
+
+```js
+externals: {
+  'sharp': 'commonjs sharp'
+}
+```
+
+### esbuild
+
+Ensure sharp is excluded from bundling via the
+[external](https://esbuild.github.io/api/#external)
+configuration.
+
+```js
+buildSync({
+  entryPoints: ['app.js'],
+  bundle: true,
+  platform: 'node',
+  external: ['sharp'],
+})
+```
+
+```sh
+esbuild app.js --bundle --platform=node --external:sharp
+```
+
+For `serverless-esbuild`, ensure platform-specific binaries are installed
+via the `serverless.yml` configuration.
+
+```yaml
+custom:
+  esbuild:
+    external:
+      - sharp
+    packagerOptions:
+      scripts:
+        - npm install --arch=x64 --platform=linux sharp
+```
+
+## TypeScript
+
+TypeScript definitions are published as part of
+the `sharp` package from v0.32.0.
+
+Previously these were available via the `@types/sharp` package,
+which is now deprecated.
+
+When using Typescript, please ensure `devDependencies` includes
+the `@types/node` package.
+
+## Fonts
+
+When creating text images or rendering SVG images that contain text elements,
+`fontconfig` is used to find the relevant fonts.
+
+On Windows and macOS systems, all system fonts are available for use.
+
+On macOS systems using Homebrew, you may need to set the
+`PANGOCAIRO_BACKEND` environment variable to a value of `fontconfig`
+to ensure it is used for font discovery instead of Core Text.
+
+On Linux systems, fonts that include the relevant
+[`fontconfig` configuration](https://www.freedesktop.org/software/fontconfig/fontconfig-user.html)
+when installed via package manager are available for use.
+
+If `fontconfig` configuration is not found, the following error will occur:
+```
+Fontconfig error: Cannot load default config file
+```
+
+In serverless environments where there is no control over font packages,
+use the `FONTCONFIG_PATH` environment variable to point to a custom location.
+
+Embedded SVG fonts are unsupported.
+
+## Worker threads
+
+On some platforms, including glibc-based Linux,
+the main thread must call `require('sharp')`
+_before_ worker threads are created.
+This is to ensure shared libraries remain loaded in memory
+until after all threads are complete.
+
+Without this, the following error may occur:
+```
+Module did not self-register
+```
+
+## Known conflicts
+
+### Canvas and Windows
+
+The prebuilt binaries provided by `canvas` for Windows
+from v2.7.0 onwards depend on the Visual C++ Runtime (MSVCRT).
+These conflict with the binaries provided by sharp,
+which depend on the more modern Universal C Runtime (UCRT).
+
+See [Automattic/node-canvas#2155](https://github.com/Automattic/node-canvas/issues/2155).
+
+If both modules are used in the same Windows process, the following error will occur:
+```
+The specified procedure could not be found.
+```

+# Performance
+
+A test to benchmark the performance of this module relative to alternatives.
+
+Greater libvips performance can be expected with caching enabled (default)
+and using 8+ core machines, especially those with larger L1/L2 CPU caches.
+
+The I/O limits of the relevant (de)compression library will generally determine maximum throughput.
+
+## Contenders
+
+* [jimp](https://www.npmjs.com/package/jimp) v0.22.7 - Image processing in pure JavaScript.
+* [imagemagick](https://www.npmjs.com/package/imagemagick) v0.1.3 - Supports filesystem only and "*has been unmaintained for a long time*".
+* [gm](https://www.npmjs.com/package/gm) v1.25.0 - Fully featured wrapper around GraphicsMagick's `gm` command line utility.
+* [@squoosh/lib](https://www.npmjs.com/package/@squoosh/lib) v0.4.0 - Image libraries transpiled to WebAssembly, includes GPLv3 code, but "*Project no longer maintained*".
+* [@squoosh/cli](https://www.npmjs.com/package/@squoosh/cli) v0.7.3 - Command line wrapper around `@squoosh/lib`, avoids GPLv3 by spawning process, but "*Project no longer maintained*".
+* sharp v0.32.0 / libvips v8.14.2 - Caching within libvips disabled to ensure a fair comparison.
