+Running all unit tests
+======================
+
+Since it is non-trivial to setup all dependencies for our unit testing suite,
+we provide a docker image that bundles all of them into one container, both
+phpunit for PHP and mocha for JS.
+
+You can fetch and run the image from the docker hub like this:
+
+```console
+docker run --rm --read-only -v ~/PrivateBin:/srv:ro privatebin/unit-testing
+```
+
+The parameters in detail:
+
+- `-v ~/PrivateBin:/srv:ro` - Replace `~/PrivateBin` with the location of
+  the checked out PrivateBin repository on your machine. It is recommended to
+  mount it read-only, which guarantees that your repository isn't damaged by
+  an accidentally destructive test case in it.
+- `--read-only` - This image supports running in read-only mode. Only /tmp
+  may be written into.
+- `-rm` - Remove the container after the run. This saves you doing a cleanup
+  on your docker environment, if you run the image frequently.
+
+You can also run just the php and javascript test suites instead of both:
+
+```console
+docker run --rm --read-only -v ~/PrivateBin:/srv:ro privatebin/unit-testing phpunit
+docker run --rm --read-only -v ~/PrivateBin:/srv:ro privatebin/unit-testing mocha
+```
+
+We also provide a Janitor image that includes the  Cloud9  and Theia WebIDEs as
+well as the integrated unit testing utilities. See our [docker wiki
+page](https://github.com/PrivateBin/PrivateBin/wiki/Docker#janitor-image-with-cloud9-and-theia-webide-janitortechnologyprivatebin)
