## Summary
-Simple [node.js](https://nodejs.org/) program to simulate a set of charging stations based on the OCPP-J 1.6 protocol.
+Simple [node.js](https://nodejs.org/) software to simulate a set of charging stations based on the OCPP-J 1.6 protocol as part of SAP e-Mobility solution.
+
+## Prerequisites
+
+Install the [node.js](https://nodejs.org/) LTS runtime environment:
+
+### Windows
+
+- [Chocolatey](https://chocolatey.org/):
+
+```powershell
+choco install -y nodejs-lts
+```
+
+### MacOSX
+
+- [Homebrew](https://brew.sh/):
+
+```shell
+brew install node@16
+```
+
+### GNU/Linux:
+
+- [NodeSource](https://github.com/nodesource/distributions) Node.js Binary Distributions for version >= 16.X
+
+## Installation
+
+In the repository root, run the following command:
+
+```shell
+npm install
+```
+
+## Initial configuration
+
+Copy the configuration template file [src/assets/config-template.json](src/assets/config-template.json) to [src/assets/config.json](src/assets/config.json).
+Copy the authorization RFID tags template file [src/assets/authorization-tags-template.json](src/assets/authorization-tags-template.json) to [src/assets/authorization-tags.json](src/assets/authorization-tags.json).
+
+Tweak them to your needs by following the section [configuration files syntax](README.md#configuration-files-syntax).
+
+## Start
+
+To start the program, run: `npm start`.
+
+## Start Web UI
-## Configuration syntax
+See Web UI [README.md](src/ui/web/README.md) for more information.
-All configuration files are in the JSON standard format.
+## Configuration files syntax
-The program's global configuration parameters must be within the src/assets/config.json file. A configuration template file is available at [src/assets/config-template.json](src/assets/config-template.json).
+All configuration files are in the JSON standard format.
-All charging station templates are in the directory [src/assets/station-templates](src/assets/station-templates).
+**Configuration files locations**:
-A list of RFID tags must be defined for the automatic transaction generator with the default location and name src/assets/authorization-tags.json. A template file is available at [src/assets/authorization-tags-template.json](src/assets/authorization-tags-template.json).
+- charging stations simulator configuration: [src/assets/config.json](src/assets/config.json);
+- charging station configuration templates: [src/assets/station-templates](src/assets/station-templates);
+- charging station configurations: [dist/assets/configurations](dist/assets/configurations);
+- charging station RFID tags lists: [src/assets](src/assets).
-### Global configuration
+The charging stations simulator's configuration parameters must be within the `src/assets/config.json` file. A charging station simulator configuration template file is available at [src/assets/config-template.json](src/assets/config-template.json).
+
+All charging station configuration templates are in the directory [src/assets/station-templates](src/assets/station-templates).
+
+A list of RFID tags must be defined for the automatic transaction generator with a default location and name: `src/assets/authorization-tags.json`. A template file is available at [src/assets/authorization-tags-template.json](src/assets/authorization-tags-template.json).
+
+**Configuration files hierarchy and priority**:
+
+1. charging station configuration: [dist/assets/configurations](dist/assets/configurations);
+2. charging station configuration template: [src/assets/station-templates](src/assets/station-templates);
+3. charging stations simulator configuration: [src/assets/config.json](src/assets/config.json).
+
+The charging stations simulator have an automatic configuration files reload feature at change for:
+
+- charging stations simulator configuration;
+- charging station configuration templates;
+- charging station authorization RFID tags lists.
+
+But the modifications to test have to be done to the files in the build target directory [dist/assets](dist/assets). Once the modifications are finished, they have to be reported or copied to the matching files in the build source directory [src/assets](src/assets) to ensure they will be taken into account at next build.

-## Start
+### Charging station configuration
-To start the program, run: `npm start`.
+**dist/assets/configurations/\<hashId\>.json**:
+
+The charging station configuration file is automatically generated at startup from the charging station configuration template file and is persistent.
+
+The charging station configuration file content can be regenerated partially on matching charging station configuration template file changes. The charging station serial number is kept unchanged.
+
+#### stationInfo section
+
+The syntax is similar to charging station configuration template with some added fields like the charging station id (name) and the 'Configuration' section removed.
+
+#### configurationKey section
+
+The syntax is similar to the charging station configuration template 'Configuration' section.
