 ### Description
 
-This command runs the `npm build` command on the matched folders.  This is
-useful when you install a new version of node, and must recompile all your
-C++ addons with the new binary.  It is also useful when installing with
-`--ignore-scripts` and `--no-bin-links`, to explicitly choose which
-packages to build and/or link bins.
-
-If one or more package specs are provided, then only packages with a
-name and version matching one of the specifiers will be rebuilt.
+This command does the following:
+
+1. Execute lifecycle scripts (`preinstall`, `install`, `postinstall`, `prepare`)
+2. Links bins depending on whether bin links are enabled
+
+This command is particularly useful in scenarios including but not limited to:
+
+1. Installing a new version of **node.js**, where you need to recompile all your C++ add-ons with the updated binary.
+2. Installing with `--ignore-scripts` and `--no-bin-links`, to explicitly choose which packages to build and/or link bins.
+
+If one or more package specs are provided, then only packages with a name and version matching one of the specifiers will be rebuilt.
+
+Usually, you should not need to run `npm rebuild` as it is already done for you as part of npm install (unless you suppressed these steps with `--ignore-scripts` or `--no-bin-links`).
+
+If there is a `binding.gyp` file in the root of your package, then npm will use a default install hook:
+
+```
+"scripts": {
+    "install": "node-gyp rebuild"
+}
+```
+
+This default behavior is suppressed if the `package.json` has its own `install` or `preinstall` scripts. It is also suppressed if the package specifies `"gypfile": false`
