 Notice that, with this representation, successor edges are implicitly described. The first node under another ''<node/>'' tag is seen as the successor. Additional edges would be added as ''<edge/>'' tags.
-==== Compressed project (GSZ) ====
 ==== Java resources file ====
+The third required file to open a project. It follow the same definition as the java [[https://docs.oracle.com/javase/tutorial/deployment/jar/manifestindex.html|manifest file]].
+It cannot be renamed or moved. It needs to be ''META-INF/MANIFEST.MF''.
+This is a simple text file that list the files used in the project including the **project registry** and **graph** file.
+A simple example of its content is:
+<code>
+Name: project.gs
+Content-Type: application/x-grogra-registry+xml
+Name: Model.rgg
+Content-Type: text/x-grogra-rgg; charset=UTF-8
+Name: graph.xml
+Content-Type: application/x-grogra-graph+xml
+</code>
+Each file is mapped with its name and a MimeType (i.e. the explicit type of the file. Several files could have the same extension but be processed differently).
+==== Compressed project (GSZ) ====
+A project can be compressed into an archive. The standard GroIMP extension is .gsz, but is is a simple archive. Any .zip, 7z, or other archive format would work (as long as you rename the extension .gsz).
+The archive contains all the content of the project. It can be viewed, modified, or extracted with any archive tools on you computer.
+Note that:
+  * GroIMP requires the archive extension to be .gsz.
+  * The archive need to follow the same compression order as a java package. Thus, if you want to compress the project manually you need to include first the META-INF directory.
+For instance to compress a project in the current folder you can use the command:
-===== Create a project =====
+''zip -r myProject.gsz META-INF/ *''
