-Qodo Merge will try to increase the number of lines of context, via the parameter:
-
-```
-[config]
-patch_extra_lines_before=3
-patch_extra_lines_after=1
-```
-
-Increasing this number provides more context to the model, but will also increase the token budget, and may overwhelm the model with too much information, unrelated to the actual PR code changes.
-
-If the PR is too large (see [PR Compression strategy](https://github.com/Codium-ai/pr-agent/blob/main/PR_COMPRESSION.md)), Qodo Merge may automatically set this number to 0, and will use the original git patch.

+## Bringing additional repository metadata to Qodo Merge 💎
+
+To provide Qodo Merge with additional context about your project, you can enable automatic repository metadata detection. 
+
+If you set
+
+```toml
+[config]
+add_repo_metadata = true
+```
+
+Qodo Merge will attempt to fetch repository metadata from the root directory of your PR's head branch, looking for common metadata files such as:
+[AGENT.MD](https://agents.md/), [QODO.MD](https://docs.qodo.ai/qodo-documentation/qodo-command/getting-started/setup-and-quickstart), [CLAUDE.MD](https://www.anthropic.com/engineering/claude-code-best-practices), etc.
+
+You can also specify custom filenames to search for:
+
+```toml
+[config]
+add_repo_metadata_file_list= ["file1.md", "file2.md", ...]
+```
