+p
+    |  As of v1.7.0, spaCy comes with new command line helpers to download and
+    |  link models and show useful debugging information. For a list of available
+    |  commands, type #[code python -m spacy --help].
+
++aside("Why python -m?")
+    |  The problem with a global entry point is that it's resolved by looking up
+    |  entries in your #[code PATH] environment variable. This can give you
+    |  unexpected results, especially when using #[code virtualenv]. For
+    |  instance, you may have spaCy installed on your system but not in your
+    |  current environment. The command will then execute the wrong
+    |  spaCy installation. #[code python -m] prevents fallbacks to system modules
+    |  and makes sure the correct version of spaCy is used.
+
++h(2, "download") Download
+
+p
+    |  Download #[+a("/docs/usage/models") models] for spaCy. The downloader finds the
+    |  best-matching compatible version, uses pip to download the model as a
+    |  package and automatically creates a
+    |  #[+a("/docs/usage/models#usage") shortcut link] to load the model by name.
+    |  Direct downloads don't perform any compatibility checks and require the
+    |  model name to be specified with its version (e.g., #[code en_core_web_sm-1.2.0]).
+
++code.

++h(2, "link") Link
+
+p
+    |  Create a #[+a("/docs/usage/models#usage") shortcut link] for a model,
