 This project is a tool to modify bitwardens core dll to allow me to self license.
 Beware this does janky IL magic to rewrite the bitwarden core dll and install my self signed certificate.
 
 ## Building

 ### Signing licesnses
 
-I leave this up to the reader. They're just JSON files, with a signature section. All the code is open source.
-I'll add a tool in the future to just do it for you.
+There is a tool included to generate a license (see `src/liceseGen/`)
+
+generate a PFX above using a password of `test` and then build the tool using:
+
+```bash
+./src/licenseGen/build.sh
+```
+
+This tool build ontop of the bitbetter/api container image so make sure you've built that above using the root `./build.sh` script.
+
+After that you can run the tool using:
+
+```bash
+./src/LicenseGen/run.sh <PATH TO YOUR PFX>
