+#### Editing the prompts
+The prompts for the various PR-Agent tools are defined in the `pr_agent/settings` folder.
+
+In practice, the prompts are loaded and stored as a standard setting object. Hence,
+editing them is similar to editing any other configuration value - just place the relevant key in `.pr_agent.toml`file, and override the default value.

+For example, if you want to edit the prompts of the [describe](./pr_agent/settings/pr_description_prompts.toml) tool, you can add the following to your `.pr_agent.toml` file:

+```
+Note that the new prompt will need to generate an output compatible with the relevant [post-process function](./pr_agent/tools/pr_description.py#L137).
