 How to use QR Code Encoder with Elixir
 ======================================
 
-For now, the only way to compile qrcode is to start erlang, and compile all the files manually.
+Add :qrcode to `mix.deps`
 ::
 
-    cd src
-    erl
+    defp deps do
+      [{:qrcode, git: “git@gitlab.com:Pacodastre/qrcode.git”}]
+    end
 
-    # In the interpreter, type the following:
-    c(gf256)
-    c(qrcode_demo)
-    c(qrcode_mask)
-    c(qrcode_matrix)
-    c(base32)
-    c(bits)
-    c(qrcode_demo)
-    c(qrcode)
-    c(qrcode_reedsolomon)
+Then run:
+::
 
-Then, whenever you have this compiled, you should have access to the functions avaiable in elixir.
+    mix deps.get
+    mix deps.compile
