-If your repository has source files with unrecognized extensions, you can configure Codacy to include them in the next analysis:
+Codacy automatically detects and analyzes languages in your repository based on a list of supported file extensions. On the repository **Settings**, tab **Languages**, you can see the list of languages that Codacy has detected and will include in the next analysis.
 
-1.  Go to your repository's **Settings**, **File Extensions**.
+By default, the analysis is enabled for all languages that Codacy detects in you repository, and you can adapt them to your needs as follows:
+
+-   If your repository has source files with unrecognized extensions, you can [configure Codacy to include those extensions in the next analysis](#configuring-file-extensions)
+-   You can [disable the analysis of specific languages](#disable-language)
