-Matching pipeline
-=================
+Code Matching
+=============
+
+The aim of this tutorial is to show how to use the MatchCode.io API to perform
+code matching on an archive of files.
+
+.. note::
+ This tutorial assumes that you have a working installation of PurlDB. If you
+ don't, please refer to the `installation
+ <../purldb/overview.html#installation>`_ page.
+
+Throughout this tutorial, we will use ``pkg:npm/deep-equal@1.0.1`` and a
+modified copy of ``index.js`` from it.

+
+Instructions
+------------
+
+- First, index the package ``pkg:npm/deep-equal@1.0.1``::
+
+ /api/collect/?purl=pkg:npm/deep-equal@1.0.1
+
+- Visit ``/api/matching/`` and POST a new matching request.
+
+.. note::
+ Whether you follow this tutorial and previous instructions using cURL or
+ Python script, the final results should be the same.
+
+.. code-block:: bash
+
+ api_url="http://localhost/api/matching/"
+ content_type="Content-Type: application/json"
+ upload_file="upload_file=@"
+ curl -X POST "$api_url" -H "$content_type" -F "$upload_file"
+
+- When the match has completed, the results can be seen at ``/api/matching//results``
+
+.. code-block:: json
+
+ {
+ }
