+# ENVIRONMENT
+there is a docker image that contains the entire toolchain + flashing utility. first, you need to build the base docker image with the following script located in the ch32v-insert-coin directory:
+```shell
+$ ./init.sh
+```
+once built, you won't need to build this again. for the remainder of your development, you can use the following script:
+```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.

 # 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.
