Petrichor is a simple, techy, client side only QOL minecraft modpack.
Petrichors aim is a better vanilla (content wise) minecraft client experience especially in the more "techy" areas like NBT handling (note as this pack is still in beta and i found a licensing issue most of the tech related features will have to wait until i implement them myself).
Petrichor also aims for full optifine resource pack and shader pack parity.
Curently Petrichor supports shaders, (hopefully) full optifine resource pack format parity, minihud hud tweaks and schematics
You can install Petrichor using anything that accepts modrinth packs (you can also export it to a curseforge format using packwiz if needed). Personally i use Prismlauncher.
NOTE! If you want the basic connected textures (glass, sandstone etc) be sure to enable the bundled resourcepack(s) from Continuity
