+# RChat - RChain support to decentralize chat (Zulip)
+
+Show case example how to make chat applications like Zulip decentralized with on-chain data.
+
+## Goal
+
+1. Extract chat messages from Zulip and store it on-chain.
+1. Read on-chain tables, keys and messages.
+1. _TODO: Import messages to Zulip_.
+
+## Install nodejs dependencies
+
+```sh
+npm install
+```
+
+## Run local Zulip server with RChain nodes
+
+Control of the whole process is defined with `npm` scripts in [package.json](package.json).
+
+The first step is to start Zulip with its dependencies and RNode instances which will store on-chain data. Starting from fresh it will take a few minutes to complete. Check _docker-compose_ logs and web access for more info.
+
+_TODO: Read-only RNode is defined in configuration but not currently used. Additional info should be provided how to read exported on-chain data._
+
+```sh
+npm run start-docker
+```
+
+To control docker-compose services which includes both [docker-compose.yml](docker-compose.yml) and [docker-compose-zulip.yml](docker-compose-zulip.yml) this npm script can be used.
+
+```sh
+# Get logs from all containers
+npm run dc -- logs -f
+
+# Get logs only from bootstrap RNode
+npm run dc -- logs -f boot
+```
+
+### Check when Zulip and RNode are started from the browser
+
+Zulip: [https://localhost:1443/](https://localhost:1443/).  
+RNode: [http://localhost:40403/status](http://localhost:40403/status).
+
+# Configure initial Zulip account (organization)
+
+To login to a locally started Zulip instance it's necessary to follow the Zulip procedure and create an organization with an initial account.
+
+This command will print a temporary link to access the initial Zulip configuration. Follow the link, create your account and login to Zulip server.
+
+```sh
+npm run zulip-gen-org-link
+```
+
+## Configure smart contract to store chat messages
+
+This step is necessary to execute only once when RChain nodes are started from a fresh state.
+
+Creates a main contract with operations to insert DB data on-chain.
+
+**Result of these deploys will produce URI output which must be updated in [**.env**](.env) file.**
+
+```sh
+npm run iddb-deploy
+```
+
+After __.env__ file is updated with __IDDB_CONTRACT_URI__ execute command to create a contract for Zulip DB.
+
+```sh
+npm run myzulipdb-deploy
+```
+
+Update __DB_CONTRACT_URI__ in __.env__ file which is used as part of private channel for insert operations ([chain_replica.mjs](chain_replica.mjs)) and to get read-only channel for read operations ([read-db.mjs](read-db.mjs)).
+
+_NOTE: Whenever `iddb-deploy` and `myzulipdb-deploy` are deployed again the corresponding record in __.env__ file must be updated._
+
+## Start JS script to process new messages from Zulip and import on-chain
+
+```sh
+npm start
+```
+
+## Stop containers and clean data
+
+Stop and remove all containers (data stored on disk will not be touched).
+
+```sh
+npm run dc -- down
+```
+
+Delete all data on disk. `sudo` is needed because RNode uses _root_ user inside the container, so the mounted folder will be owned by _root_. 
+
+```sh
+sudo rm -R data
+```
