+# Message schemas

+This repository contains the message schemas for events published and consumed by the account
+selector and account data manager.
+
+## Generate code
+
+Generation of code is done with `buf`. Look for installation instructions here:
+
+https://github.com/bufbuild/buf
+
+Once installed, simply run:
+
+```
+buf generate --template buf.gen.yaml
+```
+
+Or use `poe`:
+
+```
+poe generate
+```
