+### Thanks and Credits
+
+I want to thanks and credit:
+
+* `pweingardt` for the [Mylyn Gilab Connector](https://github.com/pweingardt/mylyn-gitlab) which helps me in my initial plug-ins setup.
+* `zeripath` for the [Java Gitea API](https://github.com/zeripath/java-gitea-api) I used first to communicate with Gitea's instance before facing ssl and JDK 11 compliance issues. 
+* Contributors to the [GitHub Mylyn Connector](https://github.com/eclipse/egit-github) which helps me to understand how I can make GUI of the plugin different.
+
+## Authentication
+
+Starting with version 0.3.0, the *Mylyn/Gitea Tasks Connector* plugin will be signed with a self-signed certificate. 
+In addition to this _internal_ signature, a detached GPG signature is provided for all files associated with the release (including this README) in the `gpg/` directory,
+more over all commits in *Mylyn/Gitea Tasks Connector* related repositories are also now signed.
+
+Self-signed certificate finger print: `E4:DE:51:E9:22:C9:2E:41:26:50:E8:C4:C8:5C:DF:E5:B1:04:36:D8:B8:46:E5:C9:C2:EF:06:9E:29:3C:55:01`

 2. Add a new Tasks Repository, using the new *Gitea Issues* repository type.
   1. Enter the project URL (something like `http(s)://my-gitea-instance.org/myname_or_organisation/my_repository(.git)`) (the connector will disguard the `.git` if present)
-  2. Enter the API key token you have created via your Gitea’s web interface: `Settings | Applications | Generate New Token`. \
-  It's also possible to use usename/password.

If you don't have a valid certificate (like a self signed certificate), the plugin will refuse to connect. If you want to add your CA certificate to the java keystore, you have to:

+Note: Starting with Java8, Let'Encrypt Certificates are accepted default.

 * *Mylyn/Gitea Tasks Connector* is using the Gitea's instance Swagger API. It's obvious but it can only communicate with the Gitea's instance only if the Swagger API is activate. This feature is active by default, so contact your Gitea's instance administrator if it has been disabled.
 * List of Eclipse versions plugins is compliant with, is to be defined. It will be test with the version of Eclipse I'm using (Linux/Windows) in front of an *always* up to date gitea instance. 
-* If you create a new milestone or add a new member via the web interface, you have to update the repository configuration, so that the connector reloads the project members and milestones. Right click on the Gitea repository in the Task repositories view and click on "Update Repository Configuration".

 * Offline mode is not supported.
 * Out of the box support for valid certificates only. 
 * Supports only token and user/password as authentication scheme.
+* The _Project_ feature is not supported as there is no Gitea Swagger API for that (at least in version 1.13)
