 - The installer can use `git`, `curl`, or `wget` to download `nvm`, whichever is available.
 
+#### Installing in Docker
+
+To install `nvm` in Docker, you may need to prepare your image's environment in advance in order to use `node` & `npm`. Here's a winning recipe:
+
+```Dockerfile
+# set your target node version
+ENV NODE_VERSION 14.13.1
+# set NVM_DIR
+ENV NVM_DIR="$HOME/.nvm"
+# patch PATH
+ENV PATH $NVM_DIR/versions/node/v$NODE_VERSION/bin:$PATH
+# install!
+RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.36.0/install.sh | bash \
+  && source $NVM_DIR/nvm.sh \
+  && nvm install ${NODE_VERSION}
+```
+
 #### Troubleshooting on Linux
 
 On Linux, after running the install script, if you get `nvm: command not found` or see no feedback from your terminal after you type `command -v nvm`, simply close your current terminal, open a new terminal, and try verifying again.
