 __unpack__: This takes an input SoundBank file and writes all of the embedded `.wem` files to a directory.
 [ww2ogg](https://github.com/hcs64/ww2ogg/releases) can then be used to convert the `.wem` files to a playable Ogg Vorbis format. 
 
-__repack__: This takes an input SoundBank file, along with target `.wem` files and writes a new SoundBank with target wems replaced. Audiokinetic's [Wwise](https://www.audiokinetic.com/download/) tool can be used to convert any `.wav` of your choice into the `.wem` format for audio replacement.
+__replace__: This takes an input SoundBank file, along with target `.wem` files and writes a new SoundBank with target wems replaced. All metadata stored within the SoundBank will be updated to support the replacement `.wem`s. Replacement `.wem` files are allowed to be larger or smaller than the original embedded `wem`. 
 
 ## Usage

+`-b(nkpath)` specifies the path to the `.bnk` or `.nbnk` file to use as a source; replacement wems will replace the wems inside of this SoundBank.

+`-t(arget)` specifies a path to a directory that will be used to gather wem replacements. This directory will be searched for all compatible `.wem` files. Their filenames will be used as an index to the target wems to replace, starting at 1. For example, a `002.wem` file in this directory will replace the second wem in the original source SoundBank with the contents of that file. To file out what the indexes are for each `.wem` file in a SoundBank, first run the unpack command. These `.wem` files must not be manually padded; the tool will automatically add padding as needed.

 ## Limitations
 
 1. This software has not been thoroughly tested yet and isn't gaurenteed to work with all SoundBank files. Do [file a bug](https://github.com/hpxro7/bnkutil/issues/new) on this github page if you encounter a problem.
-2. Replacing wem files that are _larger_ than their original source wem file is currently not supported. This will be supported in the near future.
