+## read\_logs.rb
+
+read\_logs.rb looks in the `log/` directory for files ending with `.log`,
+`.log.1`, `.log.2.gz`, `.log.3.gz` and so forth. It filters out lines starting
+with a timestamp, `yyyy-mm-ddThh:mm:ss`, followed by random characters and a
+custom string provided as the only command line parameter. Finally
+it outputs all matched content after the provided string along with the date.
+
+The log files are read in the order based on the number in the filename.
+
+For example calling the script as
+
+```sh
+./bin/read_logs.rb 'doctrine.INFO:'
+```
+
+on a log file containing
+`[2025-02-04T19:51:49.356093+01:00] doctrine.INFO: Disconnecting [] []`
+
+will print:
+
+```
+2025-02-04 (Disconnecting [])
+```
