+## Update using Node.js package manager (npm)
+
+You can update with Node.js package manager (npm) if you originally installed OGCIO-DS with npm (mentioned above).
+
+### Find out which version you're using
+
+To find out which version of OGCIO-DS your project is using, you can run:
+
+```
+npm list @ogcio/ogcio-ds
+```
+
+If you do not have command line access, you can see the version number in the `package.json` file in the root of your project directory. For example:
+
+```json
+"@ogcio/ogcio-ds": "0.0.8"
+```
+
+## Update OGCIO-DS using npm
+
+To find out the latest version of OGCIO-DS, check the [release notes](https://github.com/ogcio/ogcio-ds/releases) in the OGCIO-DS GitHub repository.
+
+You may need to make code changes to keep OGCIO-DS working in your project, if the major version number changes when you update. The major version number is the first digit in the version number.
+
+To update to the most recent version, run:
+
+```
+npm install @ogcio/ogcio-ds@latest
+```
+
+If you want to install an earlier version, replace `latest` with the version that you want to update to. For example:
+
+```
+npm install @ogcio/[email protected]
+```
