+# imploder
+
+This util creates and extracts zip archives with the DCL Implode compression and is used mainly for modding the game MDK 2.
+
+Please note that this util intentionally doesn't add any info on modification date of the files when creating an archive. This is because setting "last_modified" adds a "UT extra field modtime" in addition to the regular "file last modified on (DOS date/time)" field. This means that files in an archive created by this util won't have any modification date written.
+
+Here is some help:
+```
+Usage: imploder <COMMAND>
+
+Commands:
+  create   Create an archive from a directory: create <directory> <archive>
+  extract  Extract an archive into a directory: extract <archive> <directory>
+  help     Print this message or the help of the given subcommand(s)
+
+Options:
+  -h, --help     Print help
+  -V, --version  Print version
+
+Examples:
+    imploder create directory/ out.zip
+    imploder extract archive.zip directory/
+
+please note that for `create` the directory contents are placed at the archive root
+```
