+Use this to add Company specific Simulation stuff like the configuration of the auth method.

+The following structure is generated by `./helperCompany.scala init`:
+

+03-simulation/src

+         | main/scala/company/simulation
+         |                     | CompanySimulation.scala

+```
+## CompanySimulation
+The Company's base class to run the Simulations.
+
+Example (generated by `./helperCompany.scala init`):
+
+```scala
+package mycompany.camundala.simulation
+
+import camundala.simulation.custom.*
+
+/**
+ * Add here company specific stuff, to run the Simulations.
+ */
+trait CompanySimulation extends BasicSimulationDsl:
+
+  override def config =
+    super.config //TODO Adjust config if needed
+
+end CompanySimulation
+```
+
+## SimulationConfig
+You can customize the Simulation Configuration.
+
+```scala
+super.config
+   .withTenantId("myTenant")
+```
+### Default Config
+
+```scala
+  // define tenant if you have one
+  tenantId: Option[String] = None,
+  // the Camunda Port
+  // there are Requests that wait until the process is ready - like getTask.
+  // the Simulation waits 1 second between the Requests.
+  // so with a timeout of 10 sec it will try 10 times (retryDuration = 1.second)
+  maxCount: Int = 10,
+  // REST endpoint of Camunda
+  endpoint: String = "http://localhost:8080/engine-rest",
+  // you can add authentication with this - default there is none.
+  // see BasicSimulationDsl / OAuthSimulationDsl for examples
+  authHeader: B => B = (b: B) => b,
+  // the maximum LogLevel you want to print the LogEntries.
+  logLevel: LogLevel = LogLevel.INFO
+```
+
+
+## Authentication
+We provide at the moment the following authentication methods:
+
+### Basic Authentication
+
+```scala
+import camundala.simulation.custom.*
+
+trait CompanySimulation extends BasicSimulationDsl:
+
+  override lazy val username = sys.env.getOrElse("CAMUNDA_USER", "demo")
+  override lazy val password = sys.env.getOrElse("CAMUNDA_PASSWORD", "demo")
+  //...
+```
+
+You can override the `username` and `password` to use your credentials,
+default is `demo`/`demo`.
+
+### OAuth2 Authentication
+
+```scala
+import camundala.simulation.custom.*
+
+trait CompanySimulation extends OAuthSimulationDsl:
+
+  lazy val fsso: Fsso = Fsso(
+    s"$fssoBaseUrl/auth/realms/${config.tenantId.get}/protocol/openid-connect",
+    Map(
+      "grant_type" -> "password",
+      "client_id" -> "bpf",
+      "client_secret" -> fssoClientSecret,
+      "username" -> fssoUser,
+      "password" -> fssoPassword,
+      "scope" -> "fcs"
+    ))
+  //...
+  private lazy val fssoBaseUrl = sys.env.getOrElse("FSSO_BASE_URL", "http://host.lima.internal:8090")
+  //...
+```
+
+Here you have to provide the FSSO configuration.
+- `Fsso.url` is the URL of the FSSO Server.
+- `Fsso.bodyForm` is the body of the POST request to get the token.
