+### Changing Cmder Default `cmd.exe` Prompt Config File
+
+The default Cmder shell `cmd::Cmder` propmt is customized using `Clink` and is configured by editing a config file that exists in one of two locations:
+
+- Single User Portable Config `%CMDER_ROOT%\config\cmder_prompt_config.lua`
+- Shared Cmder install with Non-Portable Individual User Config `%CMDER_USER_CONFIG%\cmder_prompt_config.lua`
+
+If your Cmder setup does not have this file create it from `%CMDER_ROOT%\vendor\cmder_prompt_config.lua.default`
+
+Customizations include:
+
+- Colors.
+- Single/Multi-line.
+- Full path/Folder only.
+- `[user]@[host]` to the beginning of the prompt.
+- `~` for home directory.
+- `λ` symbol
+
+Documentation is in the file for each setting.
