+# Actor Crash Course
+
+## Prerequisites
+
+- Must have Rivet docker compose running
+- Must have hub running just for the device link
+
+## Actor test
+
+```bash
+cargo build
+cd examples/js-deno
+../../target/debug/rivet login --api-endpoint http://localhost:8080
+# copy the path to localhost:5080/device/link/... and finish linking
+../../target/debug/rivet deploy default
+# copy build id
+../../target/debug/rivet actor create default -t name=rng --build MY_BUILD_ID --region local --network-mode host --port protocol=tcp,name=http,host
+# copy public_hostname and public_port
+curl 127.0.0.1:20081
+../../target/debug/rivet actor destroy default --id MY_ACTOR_ID
+```
+
+## Reference
+
+- See `rivet --help` for more commands
+- rivet.jsonc config spec at `packages/toolchain/src/config/mod.rs`
+- WIP typedefs for actors [here](https://github.com/rivet-gg/rivet/blob/925b9b5c2f024f40615e910e9670655249eb2bc7/sdks/actor-types/src/internal/90_rivet_ns.ts)
+
+## Known issues
+
+- Only supports host networking
+- Networking is not working (afaik)
+- LZ4 compression for JS tars don't work (defaults to correct compression, no action needed)
+
+## Troubleshooting
+
+### `Error getting bootstrap: get project failed`
+
+Make sure to run `rivet logout` if you reset the core cluster.
+
