+# The Searcher
+
+> **[INCOMING — Mission Control, Earth]**
+>
+> Cadet, an archive arrived. Somewhere in it, a single log file
+> mentions the word `BREACH`. We need it found.
+>
+> Two commands:
+>
+> - `find <path> -name "<pattern>"` — locate files by name
+> - `grep -rl "<text>" <path>` — search file contents recursively,
+>   list only the matching file paths
+>
+> Your script must produce two files:
+>
+> 1. `logs.txt` — every `.log` file under `archive/`
+> 2. `breach.txt` — the path to the file containing `BREACH`
+>
+> [END TRANSMISSION]
+
+## Your Task
+
+In `starter/starter.sh`, write the two commands.
+
+## Objectives
+
+- `logs.txt` lists every `.log` file under `archive/`
+- `breach.txt` contains the path to the file mentioning `BREACH`

+#
+# Your script must produce two files:

+#   - breach.txt — the path to the file containing the word BREACH
