+# `@hyperledger/cactus-plugin-ledger-connector-cdl-socketio`
+
+This plugin provides `Cacti` a way to interact with Fujitsu CDL networks. Using this we can perform:
+
+- `sendSyncRequest`: Send sync-typed requests to the API.
+- `sendAsyncRequest`: Send async-typed requests to the API.
+
+## Getting started
+
+### Required software components
+
+- OS: Linux (recommended Ubuntu20.04,18.04 or CentOS7)
+- Docker (recommend: v17.06.2-ce or greater)
+- node.js v12 (recommend: v12.20.2 or greater)
+
+## Boot methods
+
+### Common setup
+
+1. Always run configure command first, from the project root directory:
+
+   ```bash
+   pushd ../..
+   npm run configure
+   popd
+   ```
+
+1. Copy default configuration
+
+- **Remember to replace default CA and to adjust the `default.yaml` configuration on production deployments!**
+  ```bash
+  mkdir -p /etc/cactus/connector-cdl-socketio
+  rm -r /etc/cactus/connector-cdl-socketio/*
+  cp -rf ./sample-config/* /etc/cactus/connector-cdl-socketio/
+  ```
+
+#### Configuring CDL API Gateway Access
+
+- Set the base URL of GW service in `cdlApiGateway.url`. Do not include `api/v1`, just the base URL. (example: `"http://localhost:3000"`).
+- If the service certificate is signed with a known CA (node uses Mozilla DB), then you can skip the next steps.
+- If the service is signed with unknown CA, you can specify the gateway certificate to trust manually:
+  - Set `cdlApiGateway.caPath` to path of API Gateway certificate (in PEM format). (example: `"/etc/cactus/connector-cdl-socketio/CA/cdl-api-gateway-ca.pem"`)
+  - (optional) If server name in cert doesn't match the one in `cdlApiGateway.url`, you can overwrite it in `cdlApiGateway.serverName`
+- (not recommended - only for development): To ignore certificate rejection (e.g. use self-signed certificate) set `cdlApiGateway.skipCertCheck` to `true`.
+
+### Docker
+
+- Docker build process will use artifacts from the latest build. Make sure `./dist` contains the version you want to dockerize.
+
+```
+# Build
+DOCKER_BUILDKIT=1 docker build ./packages/cactus-plugin-ledger-connector-cdl-socketio -t cactus-plugin-ledger-connector-cdl-socketio
+
+# Run
+docker run -v/etc/cactus/:/etc/cactus -p 5061:5061 cactus-plugin-ledger-connector-cdl-socketio
+```
+
+### Manual
+
+```
+npm run start
+```
+
+## Configuration
+
+- Validator can be configured in `/etc/cactus/connector-cdl-socketio/default.yaml` (see [sample-config](./sample-config/default.yaml) for details).
+
+## Manual Tests
+
+- `cdl-connector-manual.test` contains a Jest test script that will check every implemented operation on running CDL instance.
+- Script can be used as a quick reference for using this connector plugin.
