Contributions to ESP-IDF-CXX - fixing bugs, adding features, adding documentation - are welcome! We accept contributions via Github Pull Requests.
Currently, we use the same contribution guidelines as ESP-IDF itself as basis. Please see the ESP-IDF Contributions Guide for more information. However, the workflow is quite simplified, we only use github for collaboration. Furthermore, we use the Conventional Commits format for commits.
Please also consider the legal part: You will be required to sign the Contributor Agreement for any Pull Request.
