+npm-dist-tag(1) -- Modify package distribution tags
+===================================================
+
+## SYNOPSIS
+
+    npm dist-tag add <pkg>@<version> [<tag>]
+    npm dist-tag rm <pkg> <tag>
+    npm dist-tag ls [<pkg>]
+
+## DESCRIPTION
+
+Add, remove, and enumerate distribution tags on a package:
+
+* add:
+  Tags the specified version of the package with the specified tag, or the
+  `--tag` config if not specified.
+
+* rm:
+  Clear a tag that is no longer in use from the package.
+
+* ls:
+  Show all of the dist-tags for a package, defaulting to the package in
+  the curren prefix.
+
+A tag can be used when installing packages as a reference to a version instead
+of using a specific version number:
+
+    npm install <name>@<tag>
+
+When installing dependencies, a preferred tagged version may be specified:
+
+    npm install --tag <tag>
+
+This also applies to `npm dedupe`.
+
+Publishing a package always sets the "latest" tag to the published version.
+
+## PURPOSE
+
+Tags can be used to provide an alias instead of version numbers.  For
+example, `npm` currently uses the tag "next" to identify the upcoming
+version, and the tag "latest" to identify the current version.
+
+A project might choose to have multiple streams of development, e.g.,
+"stable", "canary".
+
+## CAVEATS
+
+This command used to be known as `npm tag`, which only created new tags, and so
+had a different syntax.
+
+Tags must share a namespace with version numbers, because they are specified in
+the same slot: `npm install <pkg>@<version>` vs `npm install <pkg>@<tag>`.
+
+Tags that can be interpreted as valid semver ranges will be rejected. For
+example, `v1.4` cannot be used as a tag, because it is interpreted by semver as
+`>=1.4.0 <1.5.0`.  See <https://github.com/npm/npm/issues/6082>.
+
+The simplest way to avoid semver problems with tags is to use tags that do not
+begin with a number or the letter `v`.
