README.md

@@ -70,5 +70,24 @@ Prebuilt ISO images for every version can be found at [pub.cloudapio.eu](https:/
 
 These images are built manually whenever I decide to make a new version, and thus don't reflect the latest changes on the `main` branch.
 
+## Is there third-party software I can use on Luna?
+
+Yes, actually! Check out the [ports](ports/) directory.
+Right now, only [bc](https://github.com/gavinhoward/bc) is ported, because right now our C Library is quite primitive and doesn't support projects more complex than that. 
+
+And bc itself doesn't run very well... most notably, user input doesn't echo. But that's on our side. At least it runs!
+
+You should also keep in mind that it is not possible to compile software written in any language other than C for Luna right now.
+
+But feel free to try to port some program yourself and add it to the ports directory!
+
+Port usage: 
+    
+`ports/add-port.sh <port-name>` will build and add a port to the list of installed ports, and the built port will automatically get installed into the system root every time you run Luna.
+    
+`ports/remove-port.sh <port-name>` will remove the port from the list of installed ports, remove built files from the system root, as well as the build directory.
+
+`ports/make-package.sh <port-name>` will compile the port and make a package archive from it, which may be used in the future with a package manager :)
