-Running analyses based on Rizin
-==================

-Now Quark also supports `Rizin`_ as one of our Android analysis frameworks. You can use option ``--core-library`` with ``rizin`` to enable the Rizin-based analysis library.
+Running in Docker
+=================
 
-.. _`Rizin`: https://github.com/rizinorg/rizin
+We could build the corresponding docker image by this command:
 
 .. code-block:: bash
 
-    quark -a Ahmyth.apk -s --core-library rizin
-
+    docker build . -t quark
 
-For now, Quark is compatible with Rizin v0.4.0. But, users don't have to installed a Rizin with that version. Quark provides a feature to automatically setup a independent Rizin. In this way, the dependency will not conflict with your environment. Type in the above command and let Quark handle everything else for you.
 
-If there is a working installation of Rizin installed in the system, Quark will check its version to determine if it is compatible. If true, Quark automatically uses it for the analysis. Otherwise, Quark uses the independent Rizin installed in the Quark directory (``~/.quark-engine``).
+When the image is ready, let's run an example to test the image:
 
-You can use option ``--rizin-path`` to specify the path of the Rizin executable.
+You may also interactively use quark in the docker container. For example:
 
 .. code-block:: bash
 
-    quark -a Ahmyth.apk -s --core-library rizin --rizin-path path_to_a_rizin_executable
+    $ docker run -v $(pwd):/tmp -it quark bash
+    (in-docker): /app/quark# cd /tmp
+    (in-docker)::/tmp# quark -a Ahmyth.apk -s
 
-Moreover, if you don't want Quark to install an independent Rizin, you can use the flag ``--disable-rizin-installation`` to disable this feature.
