+once built, you won't need to build this again. for the remainder of your development, you can use the following script to launch the environment shell:
+```shell
+$ ./launch.sh
+```
+
+this will launch the docker image and give you a shell which has all of the toolchains and flashing utilities installed. to build the firmware image and flash it to the ch32 (assuming you have a wch-linke attached) run the following from inside the env shell: 
+
 ```shell
 $ ./build-run.sh
 ```
 this will build the firmware image, and attempt to upload it to the board using `wlink`. once uploaded, it will attach a serial debugger. 
 
+to exit the serial debugger simply use `ctrl-c`. to exit the environment shell use:
+
+```shell
+$ exit

 # FLASHING
 flashing is done using the [`wlink`](https://github.com/ch32-rs/wlink?tab=readme-ov-file#install) utility. `probe-rs` also works, but can be flaky, and does not support SDI prints very well.
