+
+### Game Mechanics
+Crops will grow at a specified time which you will see in the config.\
+1000 is default (7am) As we know, Minecraft has 24000 ticks / Day\
+All crops will grow successively if their pot is watered.
+
+### Season & Greenhouse
+Season is an important part of StardewValley Farming System
+which means crops only grow in a suitable season. Inproper
+seasons will make crops into dead stage but you can use 
+greenhouse glass to allow them grow all year.\
+Season change has two modes: Automatic and Command\
+You might use command to change season to sync other plugin's season for example RealisticSeason.\
+
+### Fertilizer
+There are three templates of fertiziliers: \
+SpeedGrow: Crops have a small chance to grow two stages at a time\
+RetainingSoil: Pot have a small chance to retain its water after crops grow\
+QuailityCrops: When haveresting, players have a higher chance to get high quality crops.\
+
+### Sprinkler & WateringCan
+Sprinkler is a semi-automatic way of watering pot. You can add water to sprinkler with
+water bucket or watering can. Max storage and range can be customized.\
+Watering can also has its max storage and range. 1x1 1x3 3x3 and even 9x99 is supported!\
+
+### OverWeight
+If configurated, crops will still absorb water every day and have a very little chance to be OverWeight(gigantic) before it's dead.\
+
+### Quality
+Crops have three qualities, if you don't want this feature just disable it in config. 
+Quality is determined by the fertizilier players use and their luck!\
+
+### Harvest Repeatedly
+If configurated, crops can be harvested with hands repeatedly and return to a specified stage.
+
+### Highly Optimizied
+1.Crops only grow at the specified time and won't impact the performance in other times.\
+2.Growing judge is async and only the last step ** replace blcoks ** is sync.\
+3.Crops will not actually grow at the same time. It's laggy to replace so many blocks at the same time. They will grow in a random time(in seconds) which you can specified in the config after "grow-time"(7am default)\
+4.Defaultly crops will only grow in loaded chunks. If you want a mechanic similar to OriginRealms just DISABLE SEASON, GIGANTIC(OverWeight) and REPEATED HARVESTING.\
+In this way crops data will be removed from file after it comes to its max stage. In other words, plugin will only record the crops still on growing.\
+NEVER SET "only-grow-in-loaded-chunks" TRUE IF YOU DON'T DISABLE THREE FEATURES MENTIONED ABOVE.
