 # DID Authorisation Proxy
 
 ## Description
+
 The service implemented in the `authorization-server` subfolder together with the Nginx instance defined in the `nginx`
 subfolder of this repository makes possible to integrate Energy Web DID
 solution (https://energy-web-foundation.gitbook.io/energy-web/foundational-concepts/self-sovereign-identity#decentralized-identifiers-dids)

 ## Setting for development
 
 ### Installation

 ```shell
 yarn install
 ```
 
 ### Building and starting the development stack
+
 ```shell
 docker-compose -f docker-compose.dev.yaml up --build
 ```
 
 ### Starting the authorisation service in dev mode
+
 ```shell
 cd authorization-server
 ```

 Copy `.env.example` file to `.env` file
 
 Edit `.env` file and:

+-   set `JWT_SECRET` to contain your secret phrase used to generate and validate tokens.
+-   set `ACCEPTED_ROLES` to contain roles that DIDs are required to be enrolled to
+
+**It is recommended for CACHE_SERVER_LOGIN_PRVKEY not to have any roles. Also, the account must not be used as an end user as it is being used as a proxy user.**
 
 For the detailed env variables description check [this document](./docs/ENV_VARS.md).
 
 Execute `yarn start:dev`
 
 ### How it works
+
 Put a private key into the `PRIVATE_KEY` env variable:
+
 ```shell
 export PRIVATE_KEY=<your private key here>
 ```
 
 Generate an identity token and store it in the `IDENTITY_TOKEN` env variable:
+
 ```shell
 export IDENTITY_TOKEN=$(node generate-identity-cli/index.js -p $PRIVATE_KEY -b 999999999999)
 ```
 
 Now, you can request access and refresh tokens pair:

 curl "http://localhost:8080/auth/login" \

 To run this solution on production, you need to build docker images:
