 # Usage instructions
 
-!!! TODO !!!
+There is two ways of interacting with the server via the API or the `Client` Module
+
+## API
+
+Start a new iex session and compilie `paxos.ex` and `server.ex`:
+
+```elixir
+c "paxos.ex"; c "server.ex"
+```
+
+** Paxos needs to be compiled before the server as the server requires macros written in the paxos file **
+
+Now start 3 instances of the server:
+
+```elixir
+procs = Enum.to_list(1..3) |> Enum.map(fn x -> :"p#{x}" end)
+pids = procs |> Enum.map(fn x -> Server.start(x, procs) end)
+```
+
+After the 3 instances have been started you can use Server helper functions to communicate with the Server:
+
+```elixir
+Server.start_game(:p1, [:p1, :p2])
+Server.get_game_state(:p1, 1)
+Server.make_move(:p1, 1, 0)
+```
+
+## Using the Client
+
+Open 2 different terminals. One terminal will be the display game and the other will be used to control the game
+
+In the first terminal start an iex session with a session name:
+```
+iex --sname c1
+```
+
+In the second terminal start an iex session with a session name:
+```
+iex --sname c2
+```
+
+On the first terminal connect to the second terminal:
+```elixir
+# In c1
+Node.connect(:"c2@<computer_name>")
+```
+
+On both terminals compile paxos and server:
+```elixir
+# In both run
+c "paxos.ex"; c "server.ex"
+```
+
+On the first terminal start the servers, create a game and enter display mode:
+```elixir
+# In c1
+procs = Enum.to_list(1..3) |> Enum.map(fn x -> :"p#{x}" end)
+pids = procs |> Enum.map(fn x -> Server.start(x, procs) end)
+
+Server.start_game(:p1, [:p1, :p2])
+Client.display_game(:p1, 1)
+```
+
+You now should see something like:
+
+```
+                    0         H
+
+                                    1
+           Be
+                                       H
+
+         5                               2
+                        Be
+
+         Be                            Li
+
+
+              4                     3
+
+
+                        Be
+```
+
+The Center "Atom" is your hand, while the Letters arround are the game_state or board,
+the number represents where you can put the "Atom" in your hand
+
+
+On the second terminal start enter control mode:
+```elixir
+# In c2
+Client.control_game(:p1, 1)
+```
+
+You should see:
+```
+Type the number you want to play or q to exit:
+```
+
+Keep your mouse in the second terminal, and insert the number, where you want to make your move, and hit enter!
+
+The map should update on the top screen and now you can play the game!
