+# Updates
+
+The following directory structure shows how a update/patch package has to be structured.The purpose of the different files will be 
+covered afterwards.
+
+* {UniquePackageName.tar.gz}
+    * signature.cert
+    * Files
+        * package.json
+        * {other_files_or_subdirectories}
+       
+## Package Name
+
+The unique package name is generated by the update server. Usually they are called:
+
+* Modules: {Module Name}_{New Version}.tar.gz
+* Framework: {Framework Name}_{New Version}.tar.gz
+* Resources: {Resource Name}_{New Version}.tar.gz
+* Other Components: {Component Name}_{New Version}.tar.gz
+
+By providing unique package names it's possible to define other updates as dependencies and prevent overwriting update packages.
+
+## signature.cert
+
+The `signature.cert` contains the signature for the package which will be used to certify the origin of the package. 
+The public key provided with the application is used to decrypt the certificate and compare it to the actual package data.
+
+## Files
+
+In the files directory all files are stored.
+
+### package.json
+
+The `package.json` file contains information of the package.
+
+```
+```
+
+### Other
+
+All other files are related to updates, patches, extensions and installation. These files can be simple assets that will be used or 
+replaced in modules, classes in the framework that need to be updated and sql methods for updateing the database schema.
