+### How to Customize the Default Prompt Folder
+
+The default prompt folder is located at `$HOME/.config/codegpt/prompt`. You can change this to another directory by executing:
+
+```sh
+codegpt config set prompt.folder /path/to/your/prompt
+```
+
+To load the prompt files from the custom folder, run:
+
+```sh
+codegpt prompt --load
+```
+
+Upon execution, you will see messages similar to the following:
+
+```sh
+save code_review_file_diff.tmpl to /Users/xxxxx/.config/codegpt/prompt/code_review_file_diff.tmpl
+save summarize_file_diff.tmpl to /Users/xxxxx/.config/codegpt/prompt/summarize_file_diff.tmpl
+save summarize_title.tmpl to /Users/xxxxx/.config/codegpt/prompt/summarize_title.tmpl
+save conventional_commit.tmpl to /Users/xxxxx/.config/codegpt/prompt/conventional_commit.tmpl
+```
