+#### Getting correct Node version
+- Ensure you have the correct version of node installed, specified in `.node-version`
+- Use this command from the terminal to install nvm 
+```bash
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash
+``` 
+- Reload your terminal shell using (for Ubuntu):
+```bash
+source ~/.bashrc
+```
+- Install the specified Node version 
+```bash
+NODE_VERSION="$(tr -d '[:space:]' < .node-version)"
+nvm install "$NODE_VERSION"
+nvm use "$NODE_VERSION"
+```
+- verify the correct version was installed by running
+```bash
+node --version
+```
+and comparing the output to what is listed in `.node-version`
+#### Install npm packages
+- To install the npm packages listed in `package.json` run: 
+```bash
+ npm i 
+ ```
+### Start Development Server
