+# Analytics plugin configuration
+
+The configuration is located on `$GERRIT_SITE/etc/analytics.config` and allows
+to customize the default parameters for the analytics extraction.
+
+## Parameters
+
+- `contributors.botlike-filename-regexp`
+
+  List of regexps that identify a bot-like commit, commits that modify only
+  files whose name is a match will be flagged as bot-like.
+
+  Default: empty
+
+  Example:
+  ```ini
+  [contributors]
+    botlike-filename-regexp = .+\\.xml
+    botlike-filename-regexp = .+\\.bzl
+    botlike-filename-regexp = BUILD
+    botlike-filename-regexp = WORKSPACE
+  ```
+
+  Keep in mind that plugin configurations are written in [git-config style syntax](https://git-scm.com/docs/git-config#_syntax),
+  so you should be escaping regular expressions accordingly.
