Add data to schema column from form

Hello,
I have confused with the phoenix docs, hope someone here to answer my basic questions

So, If We have a migrated schema called players with a column :name, how we have to built a form with whom we can add data to this field :name (string)? The point is that how do we call the function to record the data to the exactly this schema players? I have tried (based on a different CRUD resource) creating a:

<%= form_for @changeset, @action, [multipart: true], fn f -> %>

<%= text_input f, :name %>

with

changeset = Home.change_players(%Players{})

and

def change_players(%Players{} = players, attrs \\ %{}) do
  Players.changeset(players, attrs)
end

but obviously its not like that

Best Regards
