 We try to stay up to date with GraphQL Java as much as possible maintaining the retro-compatibility
 with javax and Springframework 5.
 
-On each release we publish two flavours of this project:
- - the main one is using `jakarta` and Springframework `6.*` 
- - the legacy one is using `javax` and Springframework `5.*`
+On each release we publish three flavours of this project:
+ - [latest jakarta](#jakarta-and-springframework-6)
+ - [jakarta5](#jakarta5)
+ - [javax](#javax-and-springframework-5)
+ 
+All of them also supports legacy projects that can compile with older JDK versions: the minimum JDK
+version supported is the `11`.
 
-On maven central you can distinguish them from the version because the `javax` flavor has the 
-suffix `-javax`.
+## Jakarta and Springframework 6.*
+This is the main flavour using the latest version of `Jakarta` (currently the `6.*`) and the latest
+version of `Springframework` (currently the `6.*`). All the codebase can be found in the branch: 
+`master`
 
-Both of them also supports legacy projects that can compile with older JDK versions: the oldest
-supported one is the `11`.

+<dependency>
+    <groupId>com.graphql-java-kickstart</groupId>
+    <artifactId>graphql-java-servlet</artifactId>
+    <version>${graphql-java-servlet.version}</version>
+</dependency>
+```
+
+## Jakarta5
+This flavour use the `jakarta` version `5.*` and it is meant to be used for all the projects that 
+are already migrated to jakarta, but they are waiting that `jakarta6` will become more broadly used.
+All the codebase can be found in the branch: `jakarta5`
+
+```xml
+<dependency>
+    <groupId>com.graphql-java-kickstart</groupId>
+    <artifactId>graphql-java-servlet-jakarta5</artifactId>
+    <version>${graphql-java-servlet-jakarta5.version}</version>
+</dependency>
+```
+
+## Javax and Springframework 5.*
+This is the legacy flavour using the `javax` dependency and the version `5.*` of `Springframework` 
+(since it is still broadly used by a lot of projects). All the codebase can be found in the branch: 
+`master`. 
+
+```xml
+<dependency>
+    <groupId>com.graphql-java-kickstart</groupId>
+    <artifactId>graphql-java-servlet-javax</artifactId>
+    <version>${graphql-java-servlet.version}</version>
+</dependency>
+```
