+### Positron
+
+[Positron](https://positron.posit.co/) is an IDE for data science based on
+Code OSS, which has deep integration with R.
+Positron does not have an extension like Visual Studio Code's Dev Containers extension,
+so it cannot control Dev Containers from Positron, and it requires to use
+[Remote SSH](https://positron.posit.co/remote-ssh.html) to connect to the container.
+
+The easiest way to connect to a container with Positron is to create a Dev Container
+with [DevPod](https://devpod.sh/), which has Positron support and automatically
+creates the container and connects to it from Positron.
