I skimmed the changes and they seem good to me. Haven't tested anything

I just tested these changes locally, they seem to work fine.

The only thing that seems wrong to me is the "Building and Using" readme changes. You shouldn't have to manually run tsc, and for local tests/debugging you don't have to use pm2, yarn start should work fine. Could you change it to something like this?

## Building and Using

We use [yarn](https://yarnpkg.com/) instead of npm. Execute `yarn` in the root of the repository to install dependencies and build the project. Then `yarn start` to run the server. You can run `yarn start --help` to get a list of available options. You can also configure the server with environment variables, or with a .env file.

For a production environment, you can use [pm2](https://pm2.keymetrics.io/) like so: `pm2 start built/start.js --name multi`. pm2 will restart the server if it crashes, among other things.

To connect to a local server, disconnect from EO (from network options) and then connect to `127.0.0.1`. (The default server is `multi.etternaonline.com`)
