+fun Prov.myCustomTask() = task {

-
-If you're having a deeper look into the provs code, you'll see regularly a task definition like this and might wonder ...
-
-### What is a task ?
+## What is a task ?
 
 A task is the **basic execution unit** in provs. When executed, each task produces exactly one result (line) with either success or failure.
 
@@ -26,9 +12,108 @@ The success or failure is computed automatically in the following way:
 * a task defined with **optional** (i.e. `= optional { /* ... */ }` always returns success (even if there are failing subtasks)
 * **requireLast** defines a task which must provide an explicit result and solely this result counts for success calculation
 
+## Task declaration 
+
+### Recommended way
+
+A task can be declared by 
+
+```kotlin
+fun Prov.myCustomTask() = task { /* ... code and subtasks come here ... */ }
+// e.g.
+fun Prov.myEchoTask() = task { 
+    cmd("echo hello world!") 
+}
+```
+
+The task will succeed if all sub-tasks (called tasks during execution) have succeeded resp. if no sub-task was called.  
+
+### Alternative ways
+
+The following ways are equivalent but are more verbose:
+
+```kotlin
+// Redundant declaration of the return type (ProvResult), which is already declared by task
+fun Prov.myCustomTask(): ProvResult = task { /* ... code and subtasks come here ... */ }
+
+// Redundant parentheses behind task
+fun Prov.myCustomTask() = task() { /* ... code and subtasks come here ... */ }
+
+// Redundant definition of the task name, but could be used to output a different task name  
+fun Prov.myCustomTask() = task("myCustomTask") { /* ... code and subtasks come here ... */ }
+
+// Functionally equal, but with additional curly brackets 
+fun Prov.myCustomTask() { task { /* ... code and subtasks come here ... */ } }
+```
+
+Btw, the following lines and WILL NOT work as expected. 
+Due to too much lamda nesting, the code within the task is NOT executed:
+
+```kotlin
+fun Prov.myCustomTask() = { task { /* ... code and subtasks come here ... */ } }
+fun Prov.myCustomTask() {{ task { /* ... code and subtasks come here ... */ } }}
+```
+
+### Add custom results
+
+If you want to add a result explicitly, you can use method `addResultToEval`.
+This maxy be used e.g. to add explicitly an error line, like in: 
+
+```kotlin
+fun Prov.myCustomTask() = task {
+    /* some other code ... */
+    addResultToEval(ProvResult(false, err = "my error msg"))
+    /* some other code ... */
+}
+```
+or alternatively you can use `taskWithResult`.
+
+#### TaskWithResult
+
+In case you want to include the return value (of type `ProvResult`) of a task to be added to the evaluation, 
+you can use `taskWithResult` instead of `task` and return the value, e.g. like 
+
+```kotlin
+fun Prov.myEchoTask() = taskWithResult { 
+    cmd("echo hello world!") 
+    // ...
+    ProvResult(false, "Error: ... error message ...")  // will be the returned as return value and included in the evaluation 
+}
+```
+
+IMPORTANT: the value you want to return must be placed at the end of the lambda code (as usual in functional programming)!
+The following will NOT work as expected:
+
+```kotlin
+fun Prov.myEchoTask() = taskWithResult {
+    ProvResult(false, "Error: ... error message ...")  // will be ignored
+    // the result from the call below (i.e. from task "cmd") will be returned by myEchoTask,
+    // which is redundant as its result is already included in the evaluation anyway. 
+    cmd("echo hello world!")  
+}
+```
+
+
+### Task output
+
+If a task is run e.g. with `local().myEchoTask()`, it will produce output like
+```
+>  Success -- myEchoTask 
+--->  Success -- cmd [/bin/bash, -c, echo hello world!]
+```
+

-## Architecture

-Multiple architectural layers provide different levels of functionality:

-## Module structure

-For the modules we use domain-drive design according to:

-## Module dependencies

-
-__Explanation__:
-
-Modules:
-
-<ol type="A">
-  <li>Common module: has both a domain layer and an infrastructure layer</li>
-  <li>Module with only domain layer: e.g. for very simple logic where no infrastructure layer is needed</li>
-  <li>Module with only infrastructure layer: these are often _utility modules_, which provide a collection of utility functions</li>

-Dependencies:
-
-1. Domain layer calls (a function in) the infrastructure layer of the same module
-    * _Common practice of dependencies within a module_
-1. Domain layer calls (a function in) the domain layer another module
-    * _Common practice of dependencies between modules_
-1. Base layer calls domain layer
-    * _Usually not recommended!_
-4. Domain layer calls infrastructure layer in another module
-    * _This sometimes can make sense, e.g. if module B just needs some low-level function of module D instead of full provisioning. 
-      However, in most cases it is recommended to call the domain layer of module D whenever possible_
-5. Domain layer calls infrastructure layer in another module, which only has infrastructure layer
-    * _Common practice for calling utility modules, which don't have a domain layer._

+## example2
+```kotlin
+fun Prov.provisionIdeDesktop(onlyModules: List<String>? = null) {
+    if (onlyModules == null) {
+        aptInstall(OPEN_VPM)
+    }
+}
+```
+
+## Decission
+
+We use extension function and composed static.
+
+## Reason
+
+1. Similar to composed objects we can easily mock `aptInstall` in tests. Both solutions are equivalent.
+2. Inheritance in case of composed objects we can solve by static composition.
+3. Object composition we can solve by static composition.
+
+There is no reason left to change the current implementd pattern.
