<refsection><title>Description</title>
<para>The command <command>nix-pull</command> obtains a list of
pre-built store paths from the URL <replaceable>url</replaceable>, and
for each of these store paths, registers a substitute derivation that
downloads and unpacks it into the Nix store. This is used to speed up
installations: if you attempt to install something that has already
been built and stored into the network cache, Nix can transparently
re-use the pre-built store paths.</para>
<para>The file at <replaceable>url</replaceable> must be compatible
with the files created by <replaceable>nix-push</replaceable>.</para>
