+Salmiac
+======
+
+
+A confidential VM running unmodified container images in AWS [Nitro Enclaves](https://aws.amazon.com/ec2/nitro/).
+Salmiac makes it possible to run an application in isolated compute environments to protect and securely process highly sensitive data.
+
+By default bare Nitro Enclaves doesn't provide any networking capability outside of the enclave environment as well
+as no persistent storage, meaning that all your data is lost when container image finishes its execution.
+
+Salmiac enhances Nitro Enclaves by enabling networking for external communication and providing encrypted persistent storage.

+
+Quick Start Guide
+--------------
+
+1. Install Rust:
+   Follow [this](https://www.rust-lang.org/tools/install) guide.
+
+
+2. Install Docker:
+   Follow [this](https://docs.docker.com/engine/install/) guide.
+
+
+3. Set up your Nitro-enabled AWS EC2 instance:
+    - Install docker on your EC2:
+      Follow step #2
+    - Install nitro-cli on your EC2:
+      Follow [this](https://docs.aws.amazon.com/enclaves/latest/user/nitro-enclave-cli-install.html) guide.
+
+
+4. Build requisite docker images needed to run container converter
+   ```bash
+   # Run from the root of the repository
+   # build enclave-base image
+   cd salmiac/docker/enclave-base
+   docker build -t enclave-base .
+
+   # build parent-base image
+   cd ..//parent-base
+   docker build -t parent-base .
+    ```
+
+5. Compile container converter:
+    ```bash
+      # Run from the root of the repository
+      cd salmiac
+      ./build-converter.sh   
+    ```
+
+6. Create a simple conversion request json file
+   ```javascript
+    {
+      "input_image": {
+         "name": "<your application image tag>",         
+      },
+      "output_image": {
+         "name": "<your output image tag>",            
+      },
+      "converter_options": {
+         "debug": true
+      },
+      "nitro_enclaves_options": {
+         "cpu_count": 2,
+         "mem_size": "4096M"
+      }
+   }
+   ```
+
+7. Make your application Nitro VM-capable by running container converter with the file from previous step
+   ```bash
+      # Run from the root of the repository
+      cd tools/container-converter/target/debug
+      ./container-converter --request-file <path to file from step 4>
+    ```
+
+8. Copy converted image into your EC2 instance and run the image
+   ```bash
+      # Copy your converted image from step #7 into your EC2 isntance
+      # ...       
+      # Run copied image inside EC2
+      docker run -it --rm --privileged -v /run/nitro_enclaves:/run/nitro_enclaves <your image name>
+    ```
