* Update version-5-installation.md
The command `npm run start` doesn't work locally following these directions, but `npm run start:development` does. Based on the package.json commands, the `:development` command seems reasonable:
```
"start": "NODE_ENV=production node dist/index.js",
"start:development": "NODE_ENV=development CONCURRENCY=${CONCURRENCY:-1} TS_NODE_PROJECT=./src/tsconfig.json ts-node-dev --inspect --transpile-only --no-notify -r tsconfig-paths/register ./src/index.ts",
```
Here's the output I received from `npm run start`:
```
