Installing CraftBoot

Hello! Presumably if you are reading this, a server owner or modpack maker sent you here so you could install their modpack. Here's how you can set up their modpack with CraftBoot:

1. Download the latest version of craftboot.jar from here (make sure you get the jar file and not the source code).
2. Rename craftboot.jar to something that makes sense for the modpack you're installing (i.e. if you're installing AwesomeCraft, name it awesomecraft.jar or something). It doesn't matter what name you pick; it just has to be unique to the modpack you're installing. (important: once you've installed CraftBoot, never rename the file again)
3. Run the jar file! You can probably double-click it in most cases, but you might have to do Open With -> Java if your computer is configured oddly. (if you wanna use a command-line for some reason, the command is "java -jar whatever-you-named-it.jar")
4. You'll be asked to enter a URL. The server owner or modpack maker who sent you here should have given you a URL to enter here (they might have called it a configuration URL or a launcher.properties URL or something like that). So yeah, put that URL in! (oh and be sure to include the "http://" or "https://" bit)

Cautionary note: Do not enter the URL if it came from a source you don't trust. Malicious URLs could contain settings that would allow the perpetrator to steal your Minecraft login details! (if you are worried about a particular URL, open it in a web browser and make sure "yggdrasilAuthUrl" is nowhere to be found)

CraftBoot should now be installed. Assuming that URL was correct and everything went smoothly, CraftBoot should open up with the modpacks and launch page of the modpack you want. Double-click modpacks in the left panel to install or launch them. You will be asked to enter your Minecraft login details, and you may also be asked to select optional mods to install or not install. After that, the modpack should launch; have fun!
