 ## What you need
 ### Hardware
 1. Raspberry Pi
-1. Micro USB power adapter - a cable is also fine (you can connect to any USB port)
+1. Micro USB power adapter (check RPi requirements, but ideally 2.5A) - a cable is also fine (you can connect to any USB port)
 1. Min 8 GB (micro)SD card
 1. SD card reader (and a microSD to SD adapter if necessary)
 1. Ethernet cable - optional - you can connect the RPi to a HDMI screen (plus a USB mouse + keyboard) and connect it to WiFi as you would any computer. However, this setup is meant to be made over SSH - consider your Pi a server (even though it's on a table next to you :)). You can connect it to a display and once you input the WiFi password, just connect to the Pi via SSH from a different computer.
