 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
+
+There's no formal build script/process yet. To build your own `bitwarden/api` image run
+```bash
+dotnet restore
+dotnet publish
+docker build . -t bitbetter/api
+```
+
+replace anywhere `bitwarden/api` is used with `bitbetter/api` and give it a go. no promises
+
+## Issuing your own licenses
+
+The repo is setup to replace the licesning signing cert in bitwarden.core with my own personal self signed cert (`cert.cert`)
+If you want to be able to sign your own licenses obviously you'll have to replace it with your own self signed cert.
+
+you can generate one with openssl like so:
+```bash
+openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.cert -days 36500 -outform DER
+```
+
 ## But why? Its open source?
 
 Yes, bitwarden is great. If I didn't care about it i wouldn't be doing this.
 I was bothered that if i want to host bitwarden myself, at my house, 
 for my family to use (with the ability to share access) I would still have to pay a monthly ENTERPRISE organization fee.
-To host it myself. And maintain it myself. Basically WTH was bit wardening doing I was paying them for?
