Lines 35 to 48 in 0c2bb0e

	@spec remote_repo_create(String.t(), String.t(), boolean) :: {:ok, map} | {:error, any}
	def remote_repo_create(org_name, repo_name, private \\ false) do
	url = api_base_url() <> "org/#{org_name}/repos"
	Logger.info("remote_repo_create api endpoint: #{url}")
	params = %{
	name: repo_name,
	private: private,
	description: repo_name,
	readme: repo_name
	}
	Gitea.Http.post(url, params)
	end

I would like to be able to setup more params and be able to define the current default ones:

   params = %{ 
     name: repo_name, 
     private: private, 
     description: repo_name, 
     readme: repo_name 
   } 

Maybe in this case having a keyword list as third parameter might be a good option:

opts = [private: true. auto_init: true, ...]
def remote_repo_create(org_name, repo_name, opts) do 

linked to #18 as I want to use especially the auto_init value to have the repository created with a default Readme
