How to Install Pixelmon Reforged
First, you must install the Technic Launcher. Download it here: https://www.technicpack.net/download
Once it is downloaded, run the Launcher and let it install.
When that is finished, open up the Technic Launcher and install Pixelmon Reforged by clicking on this link https://www.technicpack.net/modpack/hallowed-fantasy-reforged.1278515 and then clicking "Install this Modpack" at the top of the page.
Once you have downloaded the modpack, launch it and when it loads, click the "Multiplayer" button. Once you have done that, click on the "Add New Server" button and copy and paste the IP "play.hallowedfantasy.com". You can then join the server.
If you are having trouble installing Pixelmon Reforged or joining the server, join our Discord server here https://discord.gg/yWBpPhJ and ask a staff member for help, or create a new thread at this link http://www.hallowedfantasy.com/forum/newthread/8590150/m/45008785 stating your issue.

If you are unable to use the Technic Launcher for some reason, you can use the normal Minecraft Launcher and install the mod by downloading it from http://reforged.gg and placing it into your .Minecraft mods folder in %appdata%. You must have the latest version of Forge for Minecraft 1.12.2 in order to run Pixelmon Reforged on the normal Minecraft Launcher. If you are unsure how to do that, watch this video https://www.youtube.com/watch?v=AlljnE9U_8U&feature=youtu.be and follow the instructions.
