-<para>The command <command>nix-push</command> produces a
-<emphasis>binary cache</emphasis>, a directory containing compressed
-Nix archives (NARs) plus some metadata of the closure of the specified
-store paths.  This directory can then be made available through a web
-server to other Nix installations, allowing them to skip building from
-source and instead download binaries from the cache

-
-<para>To add the closure of Thunderbird to a binary cache:
-
-<screen>
-$ nix-push --dest /tmp/cache $(nix-build -A thunderbird)
-</screen>
-
-Assuming that <filename>/tmp/cache</filename> is exported by a web
-server as <uri>http://example.org/cache</uri>, you can then use this
-cache on another machine to speed up the installation of Thunderbird:
-
-<screen>
-$ nix-build -A thunderbird --option binary-caches http://example.org/cache
-</screen>
-
-Alternatively, you could add <literal>binary-caches =
-http://example.org/cache</literal> to
-<filename>nix.conf</filename>.</para>
-
-<para>To also include build-time dependencies (such as source
-tarballs):
-
-<screen>
-$ nix-push --dest /tmp/cache $(nix-instantiate -A thunderbird)
-</screen>
-
-</para>
-
-<para>To generate a signed binary cache, you must first generate a key
-pair, in this example called <literal>cache.example.org-1</literal>,
-storing the secret key in <filename>./sk</filename> and the public key
-in <filename>./pk</filename>:
-
-<screen>
-$ nix-store --generate-binary-cache-key cache.example.org-1 sk pk
-
-$ cat sk
-cache.example.org-1:jcMRQYFo8pQKzTtimpQLIPeHkMYZjfhB24hGfwF+u9PuX8H8FO7q564+X3G/JDlqqIqGar3OXRRwS9N3Wh3vbw==
-
-$ cat pk
-cache.example.org-1:7l/B/BTu6ueuPl9xvyQ5aqiKhmq9zl0UcEvTd1od728=
-</screen>
-
-You can then generate a binary cache signed with the secret key:
-
-<screen>
-$ nix-push --dest /tmp/cache --key-file ./sk $(type -p firefox)
-</screen>
-
-Users who wish to verify the integrity of binaries downloaded from
-your cache would add the following to their
-<filename>nix.conf</filename>:
-
-<programlisting>
-binary-caches = http://cache.example.org
-signed-binary-caches = *
-binary-cache-public-keys = cache.example.org-1:7l/B/BTu6ueuPl9xvyQ5aqiKhmq9zl0UcEvTd1od728=
-</programlisting>
-
-Nix will then ignore any binary that has a missing, incorrect or
-unrecognised signature.</para>

-<refsection><title>Binary cache format and operation</title>
-
-<para>A binary cache with URL <replaceable>url</replaceable> only
-denotes a valid binary cache if the file
-<uri><replaceable>url</replaceable>/nix-cache-info</uri> exists.  If
-this file does not exist (or cannot be downloaded), the cache is
-ignored.  If it does exist, it must be a text file containing cache
-properties.  Here’s an example:
-
-<screen>
-StoreDir: /nix/store
-WantMassQuery: 1
-Priority: 10
-</screen>
-
-The properties that are currently supported are:
-
-<variablelist>
-
-  <varlistentry><term><literal>StoreDir</literal></term>
-
-    <listitem><para>The path of the Nix store to which this binary
-    cache applies.  Binaries are not relocatable — a binary built for
-    <filename>/nix/store</filename> won’t generally work in
-    <filename>/home/alice/store</filename> — so to prevent binaries
-    from being used in a wrong store, a binary cache is only used if
-    its <literal>StoreDir</literal> matches the local Nix
-    configuration.  The default is
-    <filename>/nix/store</filename>.</para></listitem>

-
-  <varlistentry><term><literal>WantMassQuery</literal></term>
-
-    <listitem><para>Query operations such as <command>nix-env

-    thousands of HTTP requests, to determine which packages are
-    available in binary form.  While these requests are small, not
-    every server may appreciate a potential onslaught of queries.  If
-    <literal>WantMassQuery</literal> is set to <literal>0</literal>
-    (default), “mass queries” such as <command>nix-env -qas</command>
-    will skip this cache.  Thus a package may appear not to have a
-    binary substitute.  However, the binary will still be used when
-    you actually install the package.  If
-    <literal>WantMassQuery</literal> is set to <literal>1</literal>,
-    mass queries will use this cache.</para></listitem>
-
-  </varlistentry>
-
-  <varlistentry><term><literal>Priority</literal></term>
-
-    <listitem><para>Each binary cache has a priority (defaulting to
-    50).  Binary caches are checked for binaries in order of ascending
-    priority; thus a higher number denotes a lower priority.  The
-    binary cache <uri>https://cache.nixos.org</uri> has priority
-    40.</para></listitem>
-
-  </varlistentry>
-
-</variablelist>
-
-</para>
-
-<para>Every time Nix needs to build some store path
-<replaceable>p</replaceable>, it will check each configured binary
-cache to see if it has a NAR file for <replaceable>p</replaceable>,
-until it finds one.  If no cache has a NAR, Nix will fall back to
-building the path from source (if applicable).  To see if a cache with
-URL <replaceable>url</replaceable> has a binary for
-<replaceable>p</replaceable>, Nix fetches
-<replaceable>url/h</replaceable>, where <replaceable>h</replaceable>
-is the hash part of <replaceable>p</replaceable>.  Thus, if we have a
-cache <uri>https://cache.nixos.org</uri> and we want to obtain the
-store path
-<screen>
-/nix/store/a8922c0h87iilxzzvwn2hmv8x210aqb9-glibc-2.7
-</screen>
-then Nix will attempt to fetch
-<screen>
-https://cache.nixos.org/a8922c0h87iilxzzvwn2hmv8x210aqb9.narinfo
-</screen>
-(Commands such as <command>nix-env -qas</command> will issue an HTTP
-HEAD request, since it only needs to know if the
-<filename>.narinfo</filename> file exists.)  The
-<filename>.narinfo</filename> file is a simple text file that looks
-like this:
-
-<screen>
-StorePath: /nix/store/a8922c0h87iilxzzvwn2hmv8x210aqb9-glibc-2.7
