 This is a temporary workaround until we start publishing preview versions to the public npm registry. The following is assuming you are already signed in to the github registry.
 
 1. In a new folder install dependencies manually:
-```
+```bash
 npm install @octopusdeploy/api-client @modelcontextprotocol/sdk commander dotenv zod
 ```
 
 2. Create `.npmrc` file with the following contents:
-```
+```bash
 @octopusdeploy:registry=https://npm.pkg.github.com
 ```
 
 3. Install the mcp-server:
-```
+```bash
 npm install @octopusdeploy/mcp-server
 ```
 
 4. Run it via:
-```
+```bash
 npx "your/folders/full/path" -y @octopusdeploy/mcp-server
 ```
