-Spring Tutorials
+Java and Spring Tutorials
 ================

-This project is **a collection of small and focused tutorials** each covering a single and well defined area of development. 
-Most of the tutorial projects are focused on the `Spring Framework` (and `Spring Security`).  
+This project is **a collection of small and focused tutorials** - each covering a single and well defined area of development in the Java ecosystem. 
+A strong focus of these is, of course, the Spring Framework - Spring, Spring Boot and Spring Securiyt. 
 In additional to Spring, the following technologies are in focus: `core Java`, `Jackson`, `HttpClient`, `Guava`. 

+
 Building the project
 ====================
 To do the full build, do: `mvn install -Pdefault -Dgib.enabled=false`
-
-
-Working with the code in Eclipse
-================================
-Any IDE can be used to work with the projects, but if you're using Eclipse, consider the following. 
-
- import the included **formatter** in Eclipse: 
-`https://github.com/eugenp/tutorials/tree/master/eclipse`
-
-
-CI - Jenkins
-================================
-This tutorials project is being built **[>> HERE](https://rest-security.ci.cloudbees.com/job/tutorials-unit/)**
