+[![Linux/macOS/Windows Build](https://img.shields.io/github/actions/workflow/status/websockets/utf-8-validate/ci.yml?branch=master&label=build&logo=github)](https://github.com/websockets/utf-8-validate/actions?query=workflow%3ACI+branch%3Amaster)
+
+Check if a buffer contains valid UTF-8 encoded text.
+
+## Installation
+
+```
+npm install utf-8-validate --save-optional
+```
+
+The `--save-optional` flag tells npm to save the package in your package.json
+under the
+[`optionalDependencies`](https://docs.npmjs.com/files/package.json#optionaldependencies)
+key.
+
+## API
+
+The module exports a single function that takes one argument. To maximize
+performance, the argument is not validated. It is the caller's responsibility to
+ensure that it is correct.
+
+### `isValidUTF8(buffer)`
+
+Checks whether a buffer contains valid UTF-8.
+
+#### Arguments
+
+- `buffer` - The buffer to check.
+
+#### Return value
+
+`true` if the buffer contains only correct UTF-8, else `false`.
+
+#### Example
+
+```js
+'use strict';
+
+const isValidUTF8 = require('utf-8-validate');
+
+const buf = Buffer.from([0xf0, 0x90, 0x80, 0x80]);
+
+console.log(isValidUTF8(buf));
+// => true
+```

+# node-gyp-build
+
+> Build tool and bindings loader for [`node-gyp`][node-gyp] that supports prebuilds.
+
+```
+npm install node-gyp-build
+```
+
+[![Test](https://github.com/prebuild/node-gyp-build/actions/workflows/test.yml/badge.svg)](https://github.com/prebuild/node-gyp-build/actions/workflows/test.yml)
+
+Use together with [`prebuildify`][prebuildify] to easily support prebuilds for your native modules.
+
+## Usage
+
+> **Note.** Prebuild names have changed in [`prebuildify@3`][prebuildify] and `node-gyp-build@4`. Please see the documentation below.
+
+`node-gyp-build` works similar to [`node-gyp build`][node-gyp] except that it will check if a build or prebuild is present before rebuilding your project.
+
+It's main intended use is as an npm install script and bindings loader for native modules that bundle prebuilds using [`prebuildify`][prebuildify].
+
+First add `node-gyp-build` as an install script to your native project
+
+``` js
+{
+  ...
+  "scripts": {
+    "install": "node-gyp-build"
+  }
+}
+```
+
+Then in your `index.js`, instead of using the [`bindings`](https://www.npmjs.com/package/bindings) module use `node-gyp-build` to load your binding.
+
+``` js
+var binding = require('node-gyp-build')(__dirname)
+```
+
+If you do these two things and bundle prebuilds with [`prebuildify`][prebuildify] your native module will work for most platforms
+without having to compile on install time AND will work in both node and electron without the need to recompile between usage.
+
+Users can override `node-gyp-build` and force compiling by doing `npm install --build-from-source`.
+
+Prebuilds will be attempted loaded from `MODULE_PATH/prebuilds/...` and then next `EXEC_PATH/prebuilds/...` (the latter allowing use with `zeit/pkg`)
+
+## Supported prebuild names
+
+If so desired you can bundle more specific flavors, for example `musl` builds to support Alpine, or targeting a numbered ARM architecture version.
+
+These prebuilds can be bundled in addition to generic prebuilds; `node-gyp-build` will try to find the most specific flavor first. Prebuild filenames are composed of _tags_. The runtime tag takes precedence, as does an `abi` tag over `napi`. For more details on tags, please see [`prebuildify`][prebuildify].
+
+Values for the `libc` and `armv` tags are auto-detected but can be overridden through the `LIBC` and `ARM_VERSION` environment variables, respectively.
