 # Development guideline
 These are some of the development guidelines and help to setup the library for development.
 
+## Docker
+A [Dockerfile](../Dockerfile) is provided and can be used for running test suites or any other command.
+You can either build the image and run the needed commands manually or rather use any of the following npm scripts:
+
+- `npm run docker:build` builds the docker image with the tag `asyncapi/modelina` (the rest of the scripts run this one as well).
+- `npm run docker:test` runs the main test suite.
+- `npm run docker:test:blackbox` runs the blackbox test suite.
+
 ## Environment setup
+
 To setup the environment follow these steps:
 1. Setup the project by first installing the dependencies `npm install`
-1. Make sure the tests pass by running `npm run test` script
-    - [blackbox testing](#blackbox-testing) are excluded when running the `test` script because it require some extra setup.
-1. Make sure code is well formatted and secure `npm run lint`
+2. Make sure the tests pass by running `npm run test` script
+    - [blackbox testing](#blackbox-testing) are excluded when running the `test` script because it require some extra setup. Please refer to [Blackbox testing section](#blackbox-testing) below.
+3. Make sure code is well formatted and secure `npm run lint`
 
 ## Blackbox testing
+Please refer to [Docker section](#docker) above if you wanna run the tests directly in Docker without configuring anything extra on your machine. 
+If you prefer to install all the dependencies locally, keep reading.
+
 The blackbox testing have some different requirements in order to successfully run:
 - To to run the `java` blackbox tests, you need to have JDK installed.
 - To to run the `ts` blackbox tests, you need to have TypeScript installed globally - `npm install -g typescript`.
