-# Backend Token Wallets
+# Jincor PC Backend
+This is backend module of Jincor ICO dashboard: https://contribute.jincor.com.
 
-Todo
+It was implemented to provide following functionality:
+1. ICO users sign up.
+1. Generation of Ethereum address upon user activation.
+1. Token purchase.
+1. Displaying User's transaction history.
+1. All important actions are protected with 2FA (email or google authenticator) by integration with Jincor Backend Verify service (https://github.com/JincorTech/backend-verify)
+1. For more info check API docs: https://jincortech.github.io/backend-ico-dashboard
+
+## Technology stack
+
+1. Typescript, Express, InversifyJS (DI), TypeORM (MongoDB interaction).
+1. Web3JS - interaction with Ethereum client. ICO backend supports any JSON-RPC compliant client.
+1. Mocha/chai - unit/functional tests.
+1. Docker.
+
+## How to start development and run tests?
+
+1. Clone this repo.
+1. Run `docker-compose build --no-cache`.
+1. Run `docker-compose up -d`.
+1. Run `cp .env.test .env`.
+1. To install dependencies run `docker-compose exec ico npm i`.
+1. Run tests `docker-compose exec ico npm test`.
+
+## How to generate docs?
+
+1. Install aglio `npm install -g aglio`.
+1. Run `mkdir /usr/local/lib/node_modules/aglio/node_modules/aglio-theme-olio/cache`.
+1. Generate `aglio --theme-variables cyborg --theme-template triple -i apiary.apib -o ./docs/index.html`.
