 ### runectl
 `runectl` is a command line assit tool for inclavare-containers. Its usage includes:
-- Given the signature file of an Enclave, `runectl gen-token` can generate the correspondingg token file from Intel `aesmd` service.
+- Given the signature file of an Enclave, `runectl gen-token` can generate the corresponding token file from Intel `aesmd` service.
 - `runectl attest` can allow users to challenge the enclave with the assist of Intel Attestatiion Service through remote attestation requests. This function will be available soon.

-# Hardware requirements
-- Install [Intel SGX driver for Linux](https://github.com/intel/linux-sgx-driver#build-and-install-the-intelr-sgx-driver), required by Intel SGX SDK && PSW.
-- Install [enable_rdfsbase kernel module](https://github.com/occlum/enable_rdfsbase#how-to-build), allowing to use `rdfsbase` -family instructions in Occlum.

-# Build and install rune
-`rune` is a CLI tool for spawning and running enclaves in containers according to the OCI specification.
-
-Please refer to [this guide](https://github.com/alibaba/inclavare-containers#rune) to build `rune` from scratch.
-
----
-
-# Build Occlum application bundle
-## Download occlum sdk image
-``` shell
-yum install -y libseccomp-devel
-mkdir "$HOME/rune_workdir"
-docker pull occlum/occlum:0.11.0-centos7.2
-docker run -it --device /dev/isgx \
-  -v $HOME/rune_workdir:/root/rune_workdir \
-  occlum/occlum:0.11.0-centos7.2
-```
-
-You can then build a hello world demo program or your product codes in this [occlum sdk container environment](https://hub.docker.com/layers/occlum/occlum/0.11.0-centos7.2/images/sha256-9c27eefe5df9db6a63ade1f722ff62c107ff119c1b17cbbf4df75f238b4b2054?context=explore).
-
-[This guide](https://github.com/occlum/occlum#hello-occlum) can help you to create your first occlum build.
-
-## Prepare the materials
-After your occlum build, execute the following commands in occlum sdk container environment:
-
-``` shell
-cp -a .occlum /root/rune_workdir
-cd /root/rune_workdir
-mkdir lib
-cp /usr/lib64/libseccomp.so.2 lib
-cp /usr/lib64/libprotobuf.so.8 lib
-cp /usr/lib64/libsgx_u*.so* lib
-cp /usr/lib64/libsgx_enclave_common.so.1 lib
-cp /usr/lib64/libsgx_launch.so.1 lib
-```
-
-## Build occlum application image
-Now you can build your occlum application image in the `$HOME/rune_workdir` directory of your host system.
-
-Type the following commands to create a `Dockerfile`:
-``` Dockerfile
-cat >Dockerfile <<EOF
-FROM centos:7.2.1511
-
-RUN mkdir -p /run/rune/.occlum
-WORKDIR /run/rune
-
-COPY lib /lib 
-COPY .occlum .occlum
-
-RUN ln -sfn .occlum/build/lib/libocclum-pal.so liberpal-occlum.so
-RUN ldconfig
-
-ENTRYPOINT ["/bin/hello_world"]
-EOF
-```
-
-and then build it with the command:
-```shell
-docker build . -t occlum-app
-```
-
-## Create bundle
-In order to use `rune` you must have your container in the format of an OCI bundle. If you have Docker installed you can use its `export` method to acquire a root filesystem from an existing Docker container.
-
-``` shell
-# create the top most bundle directory
-cd "$HOME/rune_workdir"
-mkdir rune-container
-cd rune-container
-
-# create the rootfs directory
-mkdir rootfs
-
-# export occlum-app via Docker into the rootfs directory
-docker export $(docker create occlum-app) | sudo tar -C rootfs -xvf -
-```
-
-After a root filesystem is populated you just generate a spec in the format of a config.json file inside your bundle. `rune` provides a spec command which is similar to `runc` to generate a template file that you are then able to edit.
-
-``` shell
-rune spec
-```
-
-To find features and documentation for fields in the spec please refer to the [specs](https://github.com/opencontainers/runtime-spec) repository.
-
-In order to run the hello world demo program in Occlum with `rune`, you need to change the entrypoint from `sh` to `/bin/hello_world`
-``` json
-  "process": {
-      "args": [
-          "/bin/hello_world"
-      ],
-  }
-```
-
-and then configure enclave runtime as following:
-``` json
-  "annotations": {
-      "enclave.type": "intelSgx",
-      "enclave.runtime.path": "/run/rune/liberpal-occlum.so",
-      "enclave.runtime.args": ".occlum"
-  }
-```
-
----
-
-# Run Occlum application
-Assuming you have an OCI bundle from the previous step you can execute the container in this way.
-
-``` shell
-cd "$HOME/rune_workdir/rune-container"
-sudo rune run rune-container
-```
