-## Introduction 🚀
-
-Cocos AI is a **cutting-edge platform** designed to enable secure multiparty computation (SMPC) using **Confidential Computing** and **Trusted Execution Environments (TEEs)**.
-
-It empowers organizations to collaboratively process sensitive data for AI/ML workloads while ensuring:
-
-- 🔒 **Data Privacy**: Your data stays encrypted and secure throughout the computation.
-- 🛡️ **Trust and Integrity**: Protected by hardware enclaves with robust remote attestation protocols.
-- 🤝 **Seamless Collaboration**: Multiple organizations can work together without exposing sensitive information.
+# Cocos AI
+[Cocos AI (Confdential Computing System for AI/ML)][cocos] is a platform for secure multiparty computation (SMPC)
+based on the [Confidential Computing][cc] and [Trusted Execution Environments (TEEs)][tee].

-## Features 🛠️
+With Cocos AI it becomes possible to run AI/ML workloads on combined datasets from multiple organizations
+while guaranteeing the privacy and security of the data and the algorithms.
+Data is always encrypted, protected by hardware secure enclaves (Trusted Execution Environments),
+attested via secure remote attestation protocols, and invisible to cloud processors or any other
+3rd party to which computation is offloaded.
 
-Cocos AI provides essential features for secure and efficient collaborative AI/ML:
+## Features
 
-- 🖥️ **TEE Enablement and Monitoring**: Secure VM management for deploying and monitoring workloads.
-- 🛡️ **Hardware Abstraction Layer (HAL)**: Built on a hardened Linux kernel, secure bootloader, and minimal root filesystem (minimal TCB).
-- 🕵️ **In-Enclave Agent and Networking Controller**: Essential system software for managing secure workloads.
-- 🔒 **Encrypted Data Transfer**: Asynchronous data transfer and secure result delivery.
-- 🛠️ **API for Platform Manipulation**: Programmatic control for managing workloads.
-- ✅ **Attestation and Verification Tools**: Hardware- and software-supported attestation for integrity assurance.
-- 🖱️ **Command-Line Interface (CLI)**: A user-friendly CLI for system interaction.
+Cocos AI is implementing the following features:
 
-## 🚀 Quick Start
+- TEE enablement, deployment and monitoring (secure VM manager)
+- HAL for TEEs based on hardened Linux kernel, secure bootloader and custom-tailored embedded rootfs for minimal TCB
+- In-enclave agent, netowrking controller and other system software
+- Encrypted asynchronous data transfer and result delivery
+- API for programmable platform manipulation
+- HW and SW supported attestation with verification tools
+- CLI for system interaction
+
+## Usage
+
+Clone the repo and create binaries:
 
-### Clone the Repository and Build Binaries
 ```bash
 git clone git@github.com:ultravioletrs/cocos.git
 make
 ```
 
-This will generate three binaries:
+This will create 3 binaries:
 ```bash
 ls build/
 # cocos-agent  cocos-cli  cocos-manager
 ```
 
-### Deployment Overview:
-- **Manager**: Deploy on the AMD SEV-SNP host to orchestrate workloads.
-- **Agent**: Build into the [EOS](https://github.com/ultravioletrs/eos)-based HAL for secure enclave management.
-- **CLI**: Interact with remote agents to control operations.
+- Manager can be deployed on the AMD SEV-SNP host
+- Agent can be built into [EOS][eos]-based HAL
+- CLI can be used to communicate to remote Agent.

 ## Usage
 
+#### Run Computation
+
+To run a computation, use the following command:
+
+```bash
+./build/cocos-cli manager run --computation '{"name": "my-computation"}'
+```
+
 #### Get attestation
 Retrieves attestation information from the SEV guest and saves it to a file.
 To retrieve attestation from agent, use the following command:
 ```bash
-./build/cocos-cli attestation get '<report_data>'
+./build/cocos-cli agent attestation get '<report_data>'
 ```
 
 #### Validate attestation
 Validates the retrieved attestation information against a specified policy and checks its authenticity.
 To validate and verify attestation from agent, use the following command:
 ```bash
-./build/cocos-cli attestation validate '<attestation>' --report_data '<report_data>'
+./build/cocos-cli agent attestation validate '<attestation>' --report_data '<report_data>'
 ```
 ##### Flags
 - --config: Path to a JSON file containing the validation configuration. This can be used to override individual flags.
@@ -62,60 +70,21 @@ To validate and verify attestation from agent, use the following command:
 To upload an algorithm, use the following command:
 
 ```bash
-./build/cocos-cli algo /path/to/algorithm <private_key_file_path>
+./build/cocos-cli agent algo /path/to/algorithm
 ```
 
-##### Flags
-- -a, --algorithm string        Algorithm type to run (default "bin")
--     --args stringArray        Arguments to pass to the algorithm
--     --python-runtime string   Python runtime to use (default "python3")
-- -r, --requirements string     Python requirements file
-
 #### Upload Dataset
 
 To upload a dataset, use the following command:
 
 ```bash
-./build/cocos-cli data /path/to/dataset.csv <private_key_file_path>
+./build/cocos-cli agent data /path/to/dataset.csv
 ```
 
-Users can also upload directories which will be compressed on transit. Once received by agent they will be stored as compressed files or decompressed if the user passed the decompression argument.
-
-##### Flags
-- -d, --decompress   Decompress the dataset on agent
-
-
-
 #### Retrieve result
 
 To retrieve the computation result, use the following command:
 
 ```bash
-./build/cocos-cli result <private_key_file_path>
-```
-
-#### Checksum
-When defining the manifest dataset and algorithm checksums are required. This can be done as below:
-
-```bash
-./build/cocos-cli checksum <path_to_dataset_or_algorithm>
-```
-
-#### Measure IGVM file
-We assume that our current working directory is the root of the cocos repository, both on the host machine and in the VM.
-
-`igvmmeasure` calculates the launch measurement for an IGVM file and can generate a signed version. It ensures integrity by precomputing the expected launch digest, which can be verified against the attestation report. The tool parses IGVM directives, outputs the measurement as a hex string, or creates a signed file for verification at guest launch.
-
-##### Example
-We measure an IGVM file using our measure command, run:
-
-```bash
-./build/cocos-cli igvmmeasure /path/to/igvm/file
-```
-
-The tool will parse the directives in the IGVM file, calculate the launch measurement, and output the computed digest. If successful, it prints the measurement to standard output.
-
-Here is a sample output
-```
