Description

The description here seems to be outdated.

For building a simple DIY hardware I just copied
firmware/variants/esp32s3/diy/my_esp32s3_diy_oled/
to
firmware/variants/esp32s3/DIY_ESP32S3/
and edited it.

What must be done that it can be found for building?

$ pio run --environment DIY_ESP32S3

@git2fa, Welcome to Meshtastic! 👋

Thanks for opening your first issue. If it's helpful, an easy way
to get logs is the "Open Serial Monitor" button on the Web Flasher.

If you have ideas for features, note that we often debate big ideas
in the discussions tab
first. This tracker tends to be for ideas that have community
consensus and a clear implementation.

We're very active on discord,
especially the #firmware and #alphanauts-testing channels. If you'll
be around for a while, we'd love to see you there!

Welcome to the community! ❤️

Found the solution. Forgotten to edit the first line with
[env:DIY_ESP32S3]

Where can be found the existing board-definitions?
How the DIO of the SX1276 is normally used and how this can be integrated?
