+## Getting More Detail on Startup Problems
+
+Twine logs information as it starts up and works that is not normally visible.
+If you're having problems, though, these logs might tell you more about the
+source of the problem. To see them, you'll need to start Twine from the command
+line. Once you've started Twine from the command line, you'll see Twine's logs
+in that window.
+
+### Linux
+
+How to do this depends on the distribution of Linux you use. In a desktop
+environment, you will need to start a terminal session. Gnome and KDE have apps
+(called "Gnome Terminal" and "Konsole") to do this.
+
+Once you've started a terminal session, you'll need to run Twine from wherever
+it was installed. Unfortunately, this varies by distribution as well.
+
+### MacOS
+
+Open your Applications folder, then the Utilities folder. Open Terminal in this
+folder, then type the following into the window that appears and press the Enter
+key:
+
+`/Applications/Twine.app/Contents/MacOS/Twine`
+
+### Windows
+
+Open the Start menu, then run the Command Prompt application. This will open a
+window. After it's opened, open the Start menu again and locate Twine, but
+right-click on it instead of opening the entry. Choose the _Open file location_
+option from the context menu. This will open a folder containing the Twine icon.
+Right-click this icon and choose _Copy as path_ from the context menu.
+
+Finally, go back to the Command Prompt window and right-click inside the window.
+This will paste the location of Twine into the window. If you've copied the path
+correctly, what you have pasted should end with `Twine.exe`. Don't edit what was
+pasted; only press the Enter key to launch Twine.
