 ## Usage
 
 ### ddscompress.py
+usage: `ddscompress.py [-h] [--convertcmd CMD] [--compresscmd CMD] [files ...]`
 
 Converts any number of files to `.dds` format, automatically choosing dxt1 or dxt5 depending on if the source image has anything in its alpha channel. Designed to be used with a glob, e.g: `ddscompress.py *.png`
 
-### ddsdecompress.py
+positional arguments:
+  `files`: input texture files
 
-Converts any number of files to `.png` from `.dds`. Designed to be used with a glob, e.g: `ddsdecompress.py *.dds`
+optional arguments:
+  `-h, --help `: show this help message and exit
+  `--convertcmd CMD`: name of imagemagick's convert tool (default: `convert`)
+  `--compresscmd CMD`: name of the nvidia dds compress tool (default: `nvcompress`)
+
+### ddsdecompress.py
+usage: `ddsdecompress.py [-h] [--decompresscmd CMD] [files ...]`
+
+Converts any number of files to `.tga` from `.dds`. Designed to be used with a glob, e.g: `ddsdecompress.py *.dds`
+positional arguments:
+  `files`: input dds files
+
+optional arguments:
+  `-h, --help`: show this help message and exit
+  `--decompresscmd CMD`: name of the nvidia dds decompress tool (default: `nvdecompress`)
 
 ### ddsck.py
+usage: `ddsck.py [-h] [--convertcmd CMD] [--infocmd CMD] [files ...]`
 
-Checks any number of dds files for common issues, including formats not supported by KSP, and DXT5 textures that don't use the alpha channel. Designed to be used with a glob, e.g: `ddsck.py *.dds`
