 Similarly, please don't use `processing` as the prefix for your library packages. We need to keep that name space clear for official things as well.
 
+## Release artifacts
+Below is the required structure for hosting the release artifacts of a Processing library. These files must be accessible at stable URLs. 
+
+For example, if your library is called `myLibrary` and the latest version is at `https://mywebsite.com/releases/latest/` the following links should be valid:
+
+* `https://mywebsite.com/releases/latest/myLibrary.zip`
+* `https://mywebsite.com/releases/latest/myLibrary.txt`
+* `https://mywebsite.com/releases/latest/myLibrary.pdex`
+
+> [!IMPORTANT]
+> All release artifacts must have the same base name (differing only by extension) and be hosted in the same directory.
+
+### Description of Files
+
+1.  **`myLibrary.zip` file**
+    
+    -   Contains the compiled library, documentation, and examples.
+2.  **`myLibrary.txt` file**
+    
+    -   A direct copy of the `myLibrary.properties` file but with the extension changed to `.txt`
+    -   Provides metadata such as the library's name, version, author, and dependencies.
+    -   Required for library submission and indexing in Processing’s Contribution Manager.
+3.  **`myLibrary.pdex` file**
+    
+    -   Identical to the `.zip` file but with a `.pdex` extension.
+    -   Enables direct installation via the Processing IDE using a `pde://` link.  
+        Example: `pde://https://mywebsite.com/releases/latest/myLibrary.pdex` ([read more](https://github.com/SableRaf/testURIscheme) about the `pde://` protocol)
