    * `SimpleInputAmplDistributor`: This distributor selects a fair number of amplified test method per Amplifier per test methods, if possible. The total budget is specified by the command line option ``--max-test-amplified`, and is the total number of amplified test methods to keep, _i.e._ it will be divide by the number of Amplifiers and by the number of test methods to be amplified.
                                     Example: We have 2 Amplifiers. We apply them to 2 test methods. For each test methods, amplifiers generate 4 new test methods, totally 8 amplified test methods. If the budget is 6, it will select: 3 amplified test methods per amplifier, and 2 for one test method and 2 for the other.

+#### Supported JDKs & Build Tools
+
+DSpot runs with the following Java versions:
+
+* Java 1.8
+* Java 11
+* Java 16 (used as JDK, not tested if it can support Java 16 language features)
+
+It can amplify tests of projects built with:
+
+* Maven 3.6
+* Gradle 7

 ## Minimizing and Prettifying DSpot Amplified Test Cases
 With the [DSpot Prettifier](dspot-prettifier) you can remove redundant assertions from your amplified test cases & give them more expressive names with the help of code2vec and context2vec.
