+# code2prompt
+
+> Generate AI-ready prompts from a codebase (extracts, filters and formats code for LLMs).
+> More information: <https://code2prompt.dev/docs/how_to/filter_files/>.
+
+- Generate a prompt for the current project and copy it to the clipboard (default behaviour):
+
+`code2prompt {{path/to/project}}`
+
+- Include only specific files and exclude a directory:
+
+`code2prompt {{path/to/project}} {{[-i|--include]}} "{{**/*.rs}}" {{[-e|--exclude]}} "{{tests/**}}"`
+
+- Write the prompt to a file instead of the clipboard:
+
+`code2prompt {{path/to/project}} {{[-O|--output-file]}} {{my_prompt.txt}}`
+
+- Produce structured JSON output:
+
+`code2prompt {{path/to/project}} {{[-F|--output-format]}} json`
+
+- Use a custom Handlebars template when generating the prompt:
+
+`code2prompt {{path/to/project}} {{[-t|--template]}} {{my_template.hbs}}`
