+# Launching Hyperledger Indy pool and validator
+
+## Abstract
+
+scripts in this directory builds, starts indy node pool and the cactus validator for indy
+
+## What will be built, run by using the scripts
+
+One bridge network and three containers will be started by `docker-compse up` command (after building the images).
+
+![Indy node pool and validator](./fig1.svg)
+
+- Network
+  - name: indy_net
+  - subnet: 172.16.0.0/24
+- Containers
+  - nginx container
+    - proxies requests from verifiers to the validator in the python container
+      - NOTE:  At the moment, this container does nothing. 
+      - TODO: Configure to proxy requests. Enable uWSGI (towards the python container).
+    - IP address: 172.16.0.3 on indy_net
+    - port 10080 is open to the world 
+  - python container
+    - validator code in the container receives requests from validators, which requests are proxied by the nginx container, and interacts with indy nodes in the indy_pool container
+      - NOTE:  At the moment, this container does nothing. 
+      - TODO: write validator code.
+    - IP address: 172.16.0.4
+    - port 80 is open to containers on indy_net
+  - indy_pool container
+    - indy nodes run in this container and serves requests from validator in the python container
+      - it mounts sandbox directory of host environment to save the status of Indy nodes
+    - IP address: 172.16.0.2
+    - ports 9701-9708 are open to containers on indy_net
+
+## How to build
+
+- get a copy of indy-sdk
+- edit `.env` to set environment variables
+- run `docker-compose build`
+
+### How to get a copy of indy-sdk
+
+You can use the following command to get a copy of indy-sdk source tree. 
+
+```
+git clone https://github.com/hyperledger/indy-sdk.git -b v1.16.0
+```
+### How to edit `.env` file
+
+Edit `.env` file in this directory to set the environment variables.
+
+```
+INDY_SDK_ROOT=../../git/indy-sdk/ci
+HTTP_PROXY=http://<proxy_host>:<proxy_port>
+NO_PROXY=
+```
+
+`INDY_SDK_ROOT` is the location of a Dockerfile (`indy-pool.dockerfile`) in the indy-sdk source tree, which will be used by the docker-compose command in this build process.
+
+Set `HTTP_PROXY` and `NO_PROXY` if your network requires HTTP proxy access to reach the internet.  
+
+
+### How to build docker images
+
+Use this command to build images
+
+```
+docker-compose build
+```
+## How to start and stop containers
+
+Use this command to start containers.
+
+```
+docker-compse up 
+```
+
+Press CTRL-C to stop the containers.
