+
+## Name
+
+`dotnet package download` — Download one or more NuGet packages to disk.
+
+## Synopsis
+
+```
+dotnet package download [<packages>...]
+    [--output <path>]
+    [--configfile <path> ]
+    [--prerelease]
+    [--source <package source>]
+    [--allow-insecure-connections]
+    [--interactive]
+    [--verbosity <level>]
+
+dotnet package download -h|--help
+```
+
+## Description
+
+`dotnet package download` downloads NuGet packages to a local directory. It **does not** add or update `PackageReference` entries in project files and **does not** build or restore a project.
+By default, the command downloads only the packages you specify (no transitive dependencies) to the current working directory.
+
+## Arguments
+
+* **`packages`**
+
+  One or more package IDs to download.
+  Each package can optionally include a version with `@`.
+  If a package version isn't specified, the latest version of the package is downloaded.
+  For example, `dotnet package download Contoso.Utilities` or `dotnet package download Contoso.Utilities@3.2.1`.
+  
+## Options
+
+* **`--allow-insecure-connections`**
+
+     Allows downloading from HTTP sources. Without this flag, insecure sources cause the command to error per [HTTPS-everywhere](https://aka.ms/nuget-https-everywhere) guidance.
+
+* **`--configfile <path>`**
+
+     Path to a NuGet.config to use.
+
+* **`--interactive`**
+
+     Enables interactive authentication if required.
+
+* **`-o, --output <path>`**
+
+     Directory where the package will be placed. Defaults to the current working directory.
+
+* **`--prerelease`**
+
+     Allows downloading prerelease versions.
+
+* **`-s --source <package source>`**
+
+     Specifies the NuGet package source to use.
+
+* **`-v, --verbosity <level>`**
+
+     Set the verbosity level of the command. Allowed values are `q[uiet]`, `m[inimal]`, `n[ormal]`, `d[etailed]`, and `diag[nostic]`.
+
