 # Static loading vs. dynamic loading
 
+If you add a script file with a `DO SCRIPT FILE` trigger, like we described in
+[Create your own Hello world], the script file will be copied into the mission
+file. This mission file (file extension .MIZ) is only a compressed ZIP archive
+with another file ending.
+
+If you change the script file after adding it to the mission, the changes are
+not available on mission start. You have to re-add the script after each change.
+This can be very annoying and often leads to forgetting to add the change again.
+Then you wonder why the script does not deliver the desired result.
+
+But when the mission is finished you can upload it to your dedicated DCS server
+or give it to a friend and it should run without problems. This way of embedding
+the scripts do we call `static loading` and the resulting mission is very
+portable.
+
+The other way on loading scripts is by using `DO SCRIPT`. This time the mission
+editor don't show a file browse button. Instead you see a (very small) text
+field to enter the code directly into it. It is only usefull for very small
+script snippets. But we can use it to load a file from our hard drive like this:
