The <link url="http://hg.nginx.org/njs">repository</link>
with njs sources can be cloned with the following command:
(requires <link url="https://www.mercurial-scm.org">Mercurial</link> client):
<example>
hg clone http://hg.nginx.org/njs
</example>
Then the modules should be compiled using the
<literal>--add-module</literal> configuration parameter:
<example>
./configure --add-module=<value>path-to-njs</value>/nginx
</example>
The modules can also be built as
<link doc="../ngx_core_module.xml" id="load_module">dynamic</link>:
<example>
./configure --add-dynamic-module=<value>path-to-njs</value>/nginx
</example>
</para>

<para>
To build only njs command-line <link doc="cli.xml">utility</link>, run
<literal>./configure</literal> and <literal>make njs</literal> commands
from njs root directory.
The utility is available as <literal>./build/njs</literal>.
