@ -138,14 +138,10 @@ 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.
The version subpath and file name are appended to these. There should be tarballs available
that are compressed with both gzip and Brotli, as the format downloaded will vary depending
on whether the user's version of Node supports Brotli decompression (Node.js v10.16.0+)
The version subpath and file name are appended to these.
For example, if `sharp_libvips_binary_host` is set to `https://hostname/path`
and the libvips version is `1.2.3` then the resultant URL will be
`https://hostname/path/v1.2.3/libvips-1.2.3-platform-arch.tar.br` or
`https://hostname/path/v1.2.3/libvips-1.2.3-platform-arch.tar.gz`.
`https://hostname/path/v1.2.3/libvips-1.2.3-platform-arch.tar.br`.
