+## Documentation and help output
+
+For each script, there should be documentation written in pod and help output.
+
+Docs are read with perldoc. For example:
+
+```bash
+perldoc get_unique_updates/get_unique_updates.pl
+```
+
+Each script *should* have help output. For example:
+
+```bash
+get_unique_updates.pl --help
+```
+
+## Running tests
+
+Tests are run with `prove`. To run all tests for a script, run prove on all the test files in the test directory:
+
+```bash
+prove get_unique_updates/t/*.t
+```

+=head1 SYNOPSIS
+
+get_unique_updates.pl --input-file ~/temp/ --output-dir ~/temp
+
+ Options:
+   -help                Brief help message
+   -man                 Full documentation
+   --input-file         The file to parse, generated by worklog.py (required)
+   --output-dir         Directory to store output file (defaults to the directory this script is in, only used if --output-file is provided)
+   --output-file         The name of the file to save the output to. If this is not provided, the list of packages will be printed to STDOUT.
+
+=head1 DESCRIPTION
+
+Solus uses worklog.py to generate a list of packages that were updated in a given timeframe. The file it generates includes all updates to every package.
+
+This script takes that file as input and returns a list to STDOUT or a file that has only one line per package. That line will be the latest version built for the package.
+
+You must use the markdown output type with worklog.py for use with this script. e.g.
+
+    ./worklog.py --format md builds 2024-02-04 now >| ~/temp/solus_builds_2024-02-04.md
+
+Examples:
+
+    get_unique_updates.pl --input-file ~/temp/solus_builds_2024-02-04.md
+
+    get_unique_updates.pl --input-file ~/temp/solus_builds_2024-02-04.md --output-dir ~/temp --output-file solus_unique_builds_2024-02-04.md
