TUTORIALS ON MINECRAFT MODS INSTALLATION ⧉: THE SPACE AGE MOD 1.12.2 minecraft - how to download and install Space Age 1.12.2 (with forge on Windows)

NOTE: Info on CraftStones' YouTube channel content:
Due to YouTube algorithms (most likely the algorithms, maybe something else, alternatively, or in addition) you can't meet videos on Skyblocks, SkyFactory, Pojavlauncher on the channel any more (or for now, hopefully).
Such videos (a part of) have been classified as "dangerous and/or harmful content", therefore all of them are set not to be public now.
You can still gain Pojavlauncher from its page on Play Store/Google Play (yes, the Google tool) yourself.
You can still gain Skyblocks, SkyFactory from safe CurseForge pages (ones for Minecraft Java Edition), from safe Planetminecraft topics (ones for Minecraft Java Edtion, and those for Minecraft Bedrock Edition), from safe MCPEDL pages (ones for Minecraft Bedrock Edition) yourself.
If you wonder if they're free (or whether they could give you an unauthorized free access to audio content, audiovisual content, full video games, software, or streaming services that normally require payment), keep in mind that Skyblocks Maps, SkyFactory Modpacks are free (unless otherwise explicitly stated - so read, look at their Licenses), so is Pojavlauncher, plus, you need to have the official game account to play Pojavlauncher, like you need it to use CurseForge launcher, and the official ones (Minecraft Java Edition launcher, Miecraft Bedrock Edition launcher). All the launchers that have been told here are safe (so are their pages, of course).
Sorry for the limitations.
