-### Architecture Overview

-
-
-### Relation with SOFIE
-
-Nore information about this compoment and its relation to the SOFIE project can be found in [D2.5 Federation Framework, SOFIE deliverable](https://media.voog.com/0000/0042/0957/files/SOFIE_D2.5-Federation_Framework%2C_2nd_version.pdf)
-

-### Key Technologies
-
-
-
-## Usage
-
-
-## Installation
-
-### Prerequisites
-Python 3, Hyperledger Indy SDK and the python wrapper, PyJWT are required. Use the following commands to install the prerequisites in Ubuntu 18.04 
-
-* sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys CE7709D068DB5E88
-* sudo add-apt-repository "deb https://repo.sovrin.org/sdk/deb bionic stable"
-* sudo apt-get update
-* sudo apt-get install -y libindy
-* pip3 install python3-indy pyjwt web3 
-
-
-### Configuration
-A sample configuration file is provided at conf/sample.conf
-
-### Execution from source
-From the root directory run `python3 IAA/iaa.py <configuration file>` e.g., `python3 IAA/iaa.py conf/iaa.conf`
-
-### Dockerized version
-In order to build IAA image, execute the script `docker-build.sh`. Then you can run IAA using, for example,  `docker run -tid --rm -p 9000:9000 iaa`. You can verfiry that IAA is running properly be executing the script `examples/validate_token.sh`
-
-### Usage
-The executed script creates an HTTP server that listens for REST API calls at port 9000. The REST API of IAA component is documented in 
-
-https://app.swaggerhub.com/apis-docs/nikosft/SOFIE-PDS-IAA/1.0.0#/IAA/vertoken 
-
-Please select **schema** to see all available API parameters and their documentation.
-
-#### Examples
-Verifying a DID (see also tests/test_api.py)
-```python
-user = {
-        'wallet_config': json.dumps({'id': 'user_wallet',"storage_config":{"path":"tests/indy_wallets"}}),
-        'wallet_credentials': json.dumps({'key': 'user_wallet_key'}),
-        'did' : '4qk3Ab43ufPQVif4GAzLUW'
-    }
-payload = {'token-type':'DID', 'token':user['did']}
-response  = requests.post("http://localhost:9000/verifytoken", data = payload).text
-response =json.loads(response)
-assert(response['code'] == 401)
-challenge = response['challenge']
-wallet_handle = await wallet.open_wallet(user['wallet_config'], user['wallet_credentials'])
-verkey = await did.key_for_local_did(wallet_handle, user['did'])
-signature = await crypto.crypto_sign(wallet_handle, verkey, challenge.encode())
-signature64 = base64.b64encode(signature)
-payload = {'token-type':'DID', 'token':user['did'], 'challenge': challenge, 'proof':signature64}
-response  = requests.post("http://localhost:9000/verifytoken", data = payload).text
-response =json.loads(response)
-assert(response['code'] == 200)
-await wallet.close_wallet(wallet_handle)
-```
-
-## Testing
-
-### Prerequisites
-
-Tests are executed using pytest and pytest-asyncio. To install it execute 
-
-* pip3 install -U pytest 
-* pip3 install pytest-asyncio
-
-### Running the tests
-From the root directory run `python3 -m pytest -s  tests/`
-
-
-## Integration
