%% Create the state
State1 = ot_text:create(),

%% Make an op. Let's say the request wanted to add "foo" at position 0
Op1 = #ot_text_r{i="foo",p=0},

%% Apply the operation
State2 = ot_text:apply(State1, [Op1]),

%% State2 now equals "foo"

%% We can also delete some text
Op2 = #ot_text_r{d=<<"o">>,p=1},

%% Apply the delete operation
State3 = ot_text:apply(State2, [Op2]).

%% State3 now equals "fo"
