+npm-update(1) -- Update a package
+=================================
+
+## SYNOPSIS
+
+    npm update [-g] [<name> [<name> ...]]
+
+    aliases: up, upgrade
+
+## DESCRIPTION
+
+This command will update all the packages listed to the latest version
+(specified by the `tag` config), respecting semver.
+
+It will also install missing packages. As with all commands that install
+packages, the `--dev` flag will cause `devDependencies` to be processed
+as well.
+
+If the `-g` flag is specified, this command will update globally installed
+packages.
+
+If no package name is specified, all packages in the specified location (global
+or local) will be updated.
+
+As of `npm@2.6.1`, the `npm update` will only inspect top-level packages.
+Prior versions of `npm` would also recursively inspect all dependencies.
+To get the old behavior, use `npm --depth 9999 update`.
+
+## EXAMPLES
+
+IMPORTANT VERSION NOTE: these examples assume `npm@2.6.1` or later.  For
+older versions of `npm`, you must specify `--depth 0` to get the behavior
+described below.
+
+For the examples below, assume that the current package is `app` and it depends
+on dependencies, `dep1` (`dep2`, .. etc.).  The published versions of `dep1` are:
+
+```
+{
+  "dist-tags": { "latest": "1.2.2" },
+  "versions": [
+    "1.2.2",
+    "1.2.1",
+    "1.2.0",
+    "1.1.2",
+    "1.1.1",
+    "1.0.0",
+    "0.4.1",
+    "0.4.0",
+    "0.2.0"
+  ]
+}
+```
+
+### Caret Dependencies
+
+If `app`'s `package.json` contains:
+
+```
+"dependencies": {
+  "dep1": "^1.1.1"
+}
+```
+
+Then `npm update` will install `dep1@1.2.2`, because `1.2.2` is `latest` and
+`1.2.2` satisfies `^1.1.1`.
+
+### Tilde Dependencies
+
+However, if `app`'s `package.json` contains:
+
+```
+"dependencies": {
+  "dep1": "~1.1.1"
+}
+```
+
+In this case, running `npm update` will install `dep1@1.1.2`.  Even though the `latest`
+tag points to `1.2.2`, this version does not satisfy `~1.1.1`, which is equivalent
+to `>=1.1.1 <1.2.0`.  So the highest-sorting version that satisfies `~1.1.1` is used,
+which is `1.1.2`.
+
+### Caret Dependencies below 1.0.0
+
+Suppose `app` has a caret dependency on a version below `1.0.0`, for example:
+
+```
+"dependencies": {
+  "dep1": "^0.2.0"
+}
+```
+
+`npm update` will install `dep1@0.2.0`, because there are no other
+versions which satisfy `^0.2.0`.
+
+If the dependence were on `^0.4.0`:
+
+```
+"dependencies": {
+  "dep1": "^0.4.0"
+}
+```
+
+Then `npm update` will install `dep1@0.4.1`, because that is the highest-sorting
+version that satisfies `^0.4.0` (`>= 0.4.0 <0.5.0`)
+
+### Recording Updates with `--save`
+
+When you want to update a package and save the new version as
+the minimum required dependency in `package.json`, you can use
+`npm update --save`.  For example if `package.json` contains
+
+```
+"dependencies": {
+  "dep1": "^1.1.1"
+}
+```
+
+Then `npm update --save` will install `dep1@1.2.2` (i.e., `latest`),
+and `package.json` will be modified:
+
+```
+"dependencies": {
+  "dep1": "^1.2.2"
+}
+```
+
+Note that `npm` will only write an updated version to `package.json`
+if it installs a new package.
+
+### Updating Globally-Installed Packages
+
+`npm update -g` will apply the `update` action to each globally installed
+package that is `outdated` -- that is, has a version that is different from
+`latest`.
+
+NOTE: If a package has been upgraded to a version newer than `latest`, it will
+be _downgraded_.
