+## Stop blocks from random ticks or ticks
+
+#### Random ticks
+Most blocks in the game perform randomTicks and this part is quiet optimized in itself. Yet, the more blocks you have the bigger the strain on a server. Even stairs do randomTick() for some mysterious reason. 
+Preventing randomTick() is a somewhat safe option. You just prevent some mechanics from running, like copper weathering, bamboo growing. At least in vanilla I haven't found any breaking blocks that crash the game if they are banned. I have randomly selected 50% of all the blocks in the game and banned them. No issues.
+
+Here is some data from profiler:
+  Versions: Minecraft 1.20.1, Forge 4.30.0. 
+  Mods: NoRandomTicks and WorldEdit
+  Blocks: 3800 bamboo, 5800 acacia stairs, 4200 birch leaves

+#### Ticks
+This territory is full of surprizes. Some blocks may be unaffected at all while others may stop working or only half of the functionality may be gone. E.g. minecraft:fire, if you ban it from ticking the only thing that will happen is it won't destroy block (if set on wood for example) and extinguish. So, basically behaves like on netherrack. 
+Furnaces don't give a shit. So, unless you know how a block works or ready for a long process of trail & error, I recommend to avoid this feature. 
+
+#### Fluids
+I couldn't prevent them from ticking because they have a very specific logic tied to this method which is unique to every liquid. So, if you prevent it from happening the game crashes. 
+If you know how to do that, please tell me. 
+
+## Usage
+The way I see it, this mod may help you:
+- Squeeze some performance if you are in a really tight spot. This is for a server, remember, this mod helps the server way more than to a client. 
+- Prevent some mechanics from happening while leaving the block.
