 ## Custom configuration
 
-If you call the `require('dap-python').setup` method it will create a few
-`nvim-dap` configuration entries. These configurations are general purpose
-configurations suitable for many use cases, but you may need to customize the
-configurations - for example if you want to use Docker containers.

+add additional configurations or customize them.
 
-To add your own entries you can create per project `.vscode/launch.json`
-configuration files. See `:help dap-launch.json`.

 Or you can add your own global entries by extending the
 `dap.configurations.python` list after calling the `setup` function:
 
 ```lua
-require('dap-python').setup('/path/to/python')
+require('dap-python').setup('debugpy-adapter') -- or uv, or path to python, see #usage
 table.insert(require('dap').configurations.python, {
   type = 'python',
   request = 'launch',
   name = 'My custom launch configuration',
+
+  -- `program` is what you'd use in `python <program>` in a shell
+  -- If you need to run the equivalent of `python -m <module>`, replace
+  -- `program = '${file}` entry with `module = "modulename"
   program = '${file}',
