1. Add tsetse as a dev dependency: yarn add tsetse --dev

2. Use workspace version of TypeScript

3. Add the plugin via plugins compiler option in the tsconfig. If you are using tsetse as a package then the path to the plugin might look like this:

   {
     "compilerOptions": {
       "plugins": [
         {
           "name": "tsetse"
         }
       ]
     }
   }

4. Restart the editor to reload TS initialization features.

Make sure the LSP is using (requiring) the same workspace version of TS used by the IDE.
