+# Atala PRISM V2 Performance Gatling Project
+
+Welcome to performance measurements project for Atala PRISM V2.
+
+The project is written on Kotlin and uses [Gatling](https://gatling.io/) load test framework.
+
+## Project structure
+
+The project is divided by the following main modules:
+* `common`: general module for constants and utility functions
+* `simulations`: Gatling simulations
+* `steps`: simulation steps that can be combined into simulations later
+
+## Running simulations
+
+To run all simulations, use the following command:
+```shell
+./gradlew gatlingRun
+```
+
+To run a specific simulation, specify the full path to the required simulation file.
+For example, running `ConnectionSimulation` from `simulations` package:
+```shell
+./gradlew gatlingRun-simulations.ConnectionSimulation
+```
+
+## Environments configuration
+
+There are multiple configuration environment variables available through `common.Configuration` module:
+* `ISSUER_AGENT_URL`: URL for Issuer Agent, example: `http://localhost:8080/prism-agent`
+* `ISSUER_AGENT_API_KEY`: access key for Issuer agent if hosted on remote env
+* `HOLDER_AGENT_URL`: URL for Holder Agent, example: `http://localhost:8090/prism-agent`
+* `HOLDER_AGENT_API_KEY`: access key for Holder agent if hosted on remote env
