+## Testing in Docker
+
+A `Dockerfile` has been provided which has a clean testing environment with Ubuntu Xenial.  It is very similar to the online Travis CI testing environment, but uses a more modern version of Ubuntu.
+
+See `travis/docker/README.md` for more information.
+
 ## New Tests
 
 To add a new test to an existing module, just add an inline doctest.  If the test needs access to an external module, add the import statement to the `testsetup` block in the corresponding file in `docs/source/<module>.rst`.

+# Testing in a Can
+
+This is a Dockerfile which has all of the requirements for testing pwntools.
+
+It's pretty simple, just run `make`.  All of your changes will be copied into the docker container, and the doctest suite will be executed automatically.
+
+```shell
+$ make -C travis/docker ANDROID=yes
+$ make -C travis/docker ANDROID=no TARGET=docs/source/tubes/ssh.rst
+```
+
+## Options
+
+Currently, the options `TARGET` and `ANDROID` are available.
+
+### `ANDROID`
+
+Controls whether or not to run the Android test.  The valid options are ``yes`` (the default) and ``no``.
+
+### `TARGET`
+
+This is appended to the `sphinx` command line, but generally is useful to sepcify a specific `rst` file to parse (e.g. to only run those tests).
+
+## Known Issues
+
+Currently, some tests are broken when executed in Docker.
+
+- `process.leak()` is broken, as it relies on `/proc/<pid>/mem`
+- `srop` tests are broken, since there are issues with `SYS_sigreturn` when running in Docker.
