Step 1: Finding a Place to Build
The first step you do is find a place to build your base. I personally like to build into mountains.
Step 2: Build Your Base
You can make your base 10-20 blocks underground or more and then make a room as big as you want.
Step 3: Build a House
In this step you should build a house around it or any building to cover it up. And then put a line of bookcase where the entrance.
Step 4: Secret Time
Now where your entrance is you should mark it with something that reminds you where your base is.
Step 6: Decorate
Now just decorate it! Any way you want!
This is my first instruct able I hope you guys enjoyed it!
