 ### Glossary
-repeaters - the blocks which allow to interact with redstone over internet \
-packet - a bunch of bytes sent over the internet, that do something with a single repeater
+gateways - the blocks (daylight detector) that read or emit redstone with a specified power, controlled with UDP packets \
+packet - a bunch of bytes sent over the internet, that do something with a specified gateway
+
+### Crafting
+
+To craft a gateway, combine:
+- nether star
+- ender chest
+- chorus flower
+- daylight detector
+
+### Usage
+Each gateway has an ID assigned. To view it, shift right-click a gateway.
+
+To destroy a gateway, use silk touch.
 
 ### How it works
 A packet is int / 4 bytes / 32 bits
