 # Joining a MultiWorld Game
 
-To join, set the following launch options: `-v6ap_name YourName -v6ap_ip ServerIP:Port`.
-Optionally, add `-v6ap_passwd "YourPassword"` if the room you are using requires a password. All parameters without quotation marks.
-The Name in this case is the one specified in your generated .yaml file.
-In case you are using the Archipelago Website, the IP should be `archipelago.gg`.
+To join an Archipelago MultiWorld game, you must set the game's launch options. The two mandatory launch options are:  
+  `-v6ap_name slotName`  
+  `-v6ap_ip server:port`
 
+If the game you are joining requires a password, you should also add the following to your launch options:  
+`-v6ap_passwd secretPassword`
+
+If the game is to be played offline in single-player mode, you should include this launch option:  
+`-v6ap_file filePath`
+
+Launch options may be found by right-clicking on the game in Steam and clicking "Properties" in the context menu. From there, open the "General" tab. There is a "Launch Options" setting near the bottom wherein you should enter the above options. Note that all launch options are separated by a space, and if there are spaces in your slot name or password, it should be surrounded with quotes.
 If everything worked out, you will see a textbox informing you the connection has been established after the story intro.
 
 # Playing offline
 
 To play offline, first generate a seed on the game's settings page.
-Create a room and download the `.apv6` file, and start the game with the `-v6ap_file FileName` launch argument.
+Create a room and download the `.apv6` file, include the offline single-player launch option described above.
 
 ## Installation Troubleshooting
 
-Start the game from the command line to view helpful messages regarding V6AP. These will look something like "V6AP: Message"

 ### Game no longer starts after copying the .exe
 
-Most likely you forgot to set the launch options. `-v6ap_name YourName` and `-v6ap_ip ServerIP:Port` are required for startup for Multiworlds, and
-`-v6ap_file FileName` is required for (offline) singleplayer.
-If your Name or Password have spaces in them, surround them in quotes.
+The most likely cause of a startup failure is invalid launch options. Ensure the launch options are set properly as described above in
+**Joining a MultiWorld Game**.
 
 ## Game Troubleshooting
 
 ### What happens if I lose connection?
 
-V6AP tries to reconnect a few times, so be patient.
-Should the problem still be there after about a minute or two, just save and restart the game.
+If a disconnection occurs, wait a moment to see if the game automatically reconnects itself. If the problem presists, save and restart the game.
