+We also use the Lychee Log Parser, which evaluates whether the problems detected
+by lychee are actual problems with the site or server. Whenever you add
+changes, it is your responsibility to fix all problems (even if the erroneous
+links are in a part of the code that you have not changed). In this way,
+together we will maintain the quality of the links and fix the errors that
+occur.
+
+To fix an error, open the job that crashed. In the log you will find
+information about which file the error is in and which link is affected:
+
+```bash
+2024-02-07 02:08:54 - ERROR - Broken links found!
+2024-02-07 02:08:54 - ERROR - ---
+2024-02-07 02:08:54 - ERROR - Broken links in "BROKEN.md":
+2024-02-07 02:08:54 - ERROR - ---
+2024-02-07 02:08:54 - ERROR - Broken link: https://use.fontawesome.com/
+2024-02-07 02:08:54 - ERROR - Failed: Network error: 404
+2024-02-07 02:08:54 - ERROR - ---
+```
+
+In this case, the file is `"BROKEN.md"` and the invalid link is
+`https://use.fontawesome.com/`. Check whether the path has changed or the
+page has expired. If the page has expired, use <https://web.archive.org/> to
+restore the older version. Lychee automatically suggests url fix for the broken
+links:
+
+```shell
+ 2024-02-09 13:02:52 - ERROR - ---
+2024-02-09 13:02:52 - INFO - Check if broken URL server is expired. If it's no longer available, you can fix broken links using the suggestions below:
+2024-02-09 13:02:52 - INFO - ---
+2024-02-09 13:02:52 - INFO - Suggestions for the "BROKEN.md"
+2024-02-09 13:02:52 - INFO - ---
+2024-02-09 13:02:52 - INFO - https://use.fontawesome.com/ - http://web.archive.org/web/20211220191310/https://use.fontawesome.com/
+2024-02-09 13:02:52 - INFO - ---
+```
+
+If the page does not have a saved version in the archive, remove the link and
+add an annotation.
+
+If you think that the error that appeared is not an error of the site but
+of the server you are connecting to, please open an issue and we will help
+you solve the problem.
