+# Installing
+
+You can use [`npm`](https://github.com/isaacs/npm) or [`yarn`](https://github.com/yarnpkg/yarn) to install `sqlite3`:
+
+* (recommended) Latest package:
+```bash
+npm install sqlite3
+# or
+yarn add sqlite3
+```
+* GitHub's `master` branch: `npm install https://github.com/tryghost/node-sqlite3/tarball/master`
+
+### Prebuilt binaries
+
+`sqlite3` v5+ was rewritten to use [Node-API](https://nodejs.org/api/n-api.html) so prebuilt binaries do not need to be built for specific Node versions. `sqlite3` currently builds for both Node-API v3 and v6. Check the [Node-API version matrix](https://nodejs.org/api/n-api.html#node-api-version-matrix) to ensure your Node version supports one of these. The prebuilt binaries should be supported on Node v10+.
 
-The `sqlite3` module works with:
-* Node.js v11.x, v12.x, v13.x and v14.x.
-* Electron v6.0.x, v6.1.x, v7.0.x, v7.1.x, v8.0.x, v8.1.x and v8.2.x
+The module uses [node-pre-gyp](https://github.com/mapbox/node-pre-gyp) to download the prebuilt binary for your platform, if it exists. These binaries are hosted on GitHub Releases for `sqlite3` versions above 5.0.2, and they are hosted on S3 otherwise. The following targets are currently supported:
 
-Binaries for most Node versions and platforms are provided by default via [node-pre-gyp](https://github.com/mapbox/node-pre-gyp).
+Format: `napi-v{napi_build_version}-{platform}-{arch}`
+
+* `napi-v3-darwin-x64`
+* `napi-v3-linux-x64`
+* `napi-v3-win32-ia32`
+* `napi-v3-win32-x64`
+* `napi-v6-darwin-x64`
+* `napi-v6-linux-x64`
+* `napi-v6-win32-ia32`
+* `napi-v6-win32-x64`
+
+Support for other platforms and architectures may be added in the future if CI supports building on them.
+
+If your environment isn't supported, it'll use `node-gyp` to build SQLite but you will need to install a C++ compiler and linker.
+
+### Other ways to install
+
+It is also possible to make your own build of `sqlite3` from its source instead of its npm package ([See below.](#building-from-the-source)).
 
 The `sqlite3` module also works with [node-webkit](https://github.com/rogerwang/node-webkit) if node-webkit contains a supported version of Node.js engine. [(See below.)](#building-for-node-webkit)
 
 SQLite's [SQLCipher extension](https://github.com/sqlcipher/sqlcipher) is also supported. [(See below.)](#building-for-sqlcipher)

-# Installing
-
-You can use [`npm`](https://github.com/isaacs/npm) to download and install:
-
-* The latest `sqlite3` package: `npm install sqlite3`
-
-* GitHub's `master` branch: `npm install https://github.com/mapbox/node-sqlite3/tarball/master`
-
-The module uses [node-pre-gyp](https://github.com/mapbox/node-pre-gyp) to download a pre-compiled binary for your platform, if it exists. Otherwise, it uses `node-gyp` to build the extension.
-
-It is also possible to make your own build of `sqlite3` from its source instead of its npm package ([see below](#building-from-the-source)).
-
-It is possible to use the installed package in [node-webkit](https://github.com/rogerwang/node-webkit) instead of the vanilla Node.js. See [Building for node-webkit](#building-for-node-webkit) for details.

 ## Source install
 
 To skip searching for pre-compiled binaries, and force a build from source, use
 
-    npm install --build-from-source
+```bash
+npm install --build-from-source
+```
 
 The sqlite3 module depends only on libsqlite3. However, by default, an internal/bundled copy of sqlite will be built and statically linked, so an externally installed sqlite3 is not required.
 
 If you wish to install against an external sqlite then you need to pass the `--sqlite` argument to `npm` wrapper:
 
-    npm install --build-from-source --sqlite=/usr/local
+```bash
+npm install --build-from-source --sqlite=/usr/local
+```
 
 If building against an external sqlite3 make sure to have the development headers available. Mac OS X ships with these by default. If you don't have them installed, install the `-dev` package with your package manager, e.g. `apt-get install libsqlite3-dev` for Debian/Ubuntu. Make sure that you have at least `libsqlite3` >= 3.6.
 
 Note, if building against homebrew-installed sqlite on OS X you can do:
 
-    npm install --build-from-source --sqlite=/usr/local/opt/sqlite/
+```bash
+npm install --build-from-source --sqlite=/usr/local/opt/sqlite/
+```
 
 By default the node-gyp install will use `python` as part of the installation. A
 different python executable can be specified on the command line.
 
-    npm install --build-from-source --python=/usr/bin/python2
+```bash
+npm install --build-from-source --python=/usr/bin/python2
+```
 
 This uses the npm_config_python config, so values in .npmrc will be honoured:
 
-    python=/usr/bin/python2
+```bash
+python=/usr/bin/python2
