+Build CircuitPython in a Github-Devcontainer
+============================================
+
+To build CircuitPython within a Github-Devcontainer, you need to perform
+the following steps.
+
+  1. checkout the code to a devcontainer
+
+    - click on the green "<> Code"-button
+    - select the Codespaces-tab
+    - choose "+ new with options..." from the "..."-menu
+    - in the following screen select the branch and then
+    - select ".devcontainer/cortex-m/devcontainer.json" instead
+      of "Default Codespaces configuration"
+    - update region as necessary
+    - finally, click on the green "Create codespace" button
+
+  2. Your codespace is created. Cloning the images is quite fast, but
+     preparing it for CircuitPython-development takes about 10 minutes.
+     Note that this is a one-time task.
+
+  3. During creation, you can run the command
+     `tail -f /workspaces/.codespaces/.persistedshare/creation.log`
+     to see what is going on.
+
+  4. To actually build CircuitPython, run
+
+         cd ports/raspberrypi
+         make -j $(nproc) BOARD=whatever TRANSLATION=xx_XX
+
+     This takes about 2m40s.
