+# Quick Start Guide
+
+A Docker container is provided for user to try out [bcc](https://github.com/iovisor/bcc).
+
+From your host shell:
+```bash
+docker run -it --rm \
+  --privileged \
+  -v /lib/modules:/lib/modules:ro \
+  -v /usr/src:/usr/src:ro \
+  -v /etc/localtime:/etc/localtime:ro \
+  --workdir /usr/share/bcc/tools \
+  zlim/bcc
+```
+
+Now, from the container shell, you can try the various pre-installed bcc tools.
+
+For examples, please refer to the [tutorial](docs/tutorial.md#1-general-performance).
+
+If you wish to install bcc on your host, please refer to [INSTALL.md](INSTALL.md).
