-# pillow-mbm-plugin
-Pillow plugin for KSP MBM texture files
+# Pillow-mbm
+Pillow-mbm is a plugin for [pillow](https://pillow.readthedocs.io/en/stable/) 
+that adds support for KSP's proprietary MBM texture format.
+
+## Installation
+
+To install from Pypi, run:
+
+```shell
+python -m pip install pillow-mbm
+```
+
+## Usage
+
+To decode MBM files, use the `convert-mbm` command, along with a glob or a
+list of files to decode. By default, it will convert to png in place.
+
+```
+Usage: convert-mbm [OPTIONS] [FILENAMES]...
+
+  Decode Kerbal Space Program MBM files
+
+Options:
+  -f, --flip / -F, --no-flip  Vertically flip image after converting.
+  -r, --remove                Remove input images after converting.
+  -s, --suffix TEXT           Suffix to append to output file(s). Ignored if
+                              output is a single file.
+
+  -x, --extension TEXT        Extension to use for output. Ignored if output
+                              is a single file. Output filetype is deduced
+                              from this  [default: .png]
+
+  -o, --output PATH           Output file or directory. If outputting to a
+                              file, input filenames must be only a single
+                              item. By default, files are decoded in place.
+
+  --version                   Show the version and exit.
+  --help                      Show this message and exit.
