Part 1: Strings

First off, go to the briefing screen, and on the top, click on the strings tab. Go to Briefing Text line 0 and type in the name of the mission. (i.e., "Assault in the Asteroid Field") Then go to Briefing Text line 1 and type in whatever text you want for the first step of the briefing. For this tutorial, we are going to use the text "[Red Squadron] will hyper into an asteroid belt and take out some Imperials." Remember to keep the "[" and "]" around whatever text you want highlighted. 

Then go to Briefing Text line 2 and type in whatever text you want for the second page of the briefing. Lets use the text "If you encounter and [Imperials], destroy them." 

Part 2: The briefing map. 

Step 1: Page 1: 
Shall we add some icons? I think so. Click on the add icon button and add a X-Wing icon. Move it to the bottom of the map. Click on the text button on the top of the screen , and select the second text there. It should be "[Red Squadron] will hyper into an asteroid belt and take out some Imperials." Then select the X-Wing icon, and hit the up arrow on the side of your screen until the X-Wing is about 1/3 the way up the map. 

Step 2: Page 2: 
Click on the add icon button and add a Strike Cruiser icon, and then a TIE Fighter icon. Make both of their team colors Imperial. Put them on the left side of the screen. Then push the text button and add the text that says "If you encounter and [Imperials], destroy them." Move the Strike cruiser and TIE Fighter icons to about the center of the screen by pressing the right arrow. Select the Strike Cruiser, and press the right arrow once, and do the same for the TIE fighter icon, alternating between the two and moving each one only once at a time. This will be a slow process, but makes for a smoother animation. You can put all the movement for one icon in first, then use the slider to go back to where you want another one to start moving, and put in all the movement for that one.

Once you are done moving the icons, move the slider about 5 seconds worth of length, and right click on the TIE Fighter icon and press the "Box Selection" button . Then, right click on the Strike Cruiser icon and click on the little blue "i" at the side of the screen . This will show the ship specs for that ship. Move the slider at the bottom of your screen until the ship spec time of the Strike cruiser icon is complete, and insert a "Clear all boxes" instruction by pressing the button on the top of your screen for that instruction . 

NOTE: You may have to adjust the total time of the briefing depending on how long you have made each step.
