Q&A

• Q: Why do you make this?
  A: I found difficult working on fluids under Fabric, so I made some tricks and they work surprisingly well. And later on I decided to make it a sepereate lib mod so I can use it among multiple projects.
• Q: WTF is this name for?
  A: Reservoir is a place to store water to help peoples, and this is a lib helping devs creating water(all types of fluids actually), so here it is(still nonsense but whatever lol).
• Q: Will there be a Forge/NeoForged version?
  A: No.
• Q: What about other versions?
  A: When it got out of pre-release era, I would probably port it to other major versions, but not now.
