+# Dev Container
+
+A dev container in the most simple context allows one to create a consistent development environment within a docker container that can easily be opened locally or remotely via codespaces such that contributors don't need to install anything to contribute.

+## Using A Dev Container
+
+### Locally
+
+To use this dev container locally, make sure Docker is installed and in VSCode install the `ms-vscode-remote.remote-containers` extension. Then from the root of Dioxus you can type `Ctrl + Shift + P`, then choose `Dev Containers: Rebuild and Reopen in Devcontainer`.
+
+### Codespaces
+
+TBD
+
+## Troubleshooting
+
+If having difficulty commiting with github, and you use ssh or gpg keys, you may need to ensure that the keys are being shared properly between your host and VSCode.
+
+Though VSCode does a pretty good job sharing credentials between host and devcontainer, to save some time you can always just reopen the container locally to commit with `Ctrl + Shift + P`, then choose `Dev Containers: Reopen Folder Locally`
