 ## Using OpaquePrompts with LangChain
 
 OpaquePrompts offers a [LangChain](https://python.langchain.com/docs/get_started/introduction.html) integration, enabling you to easily build privacy-preserving LLM applications. See the [OpaquePrompts page in the LangChain documentation](https://python.langchain.com/docs/integrations/llms/opaqueprompts) for more.
+
+## Troubleshooting
+
+### Version Mismatch
+
+We may make breaking changes and drop support for old versions of the Python package. If this happens, you should see an error message like this when making a `sanitize` or `desanitize` call:
+
+```
+Request sent using package version 0.1.0, but minimum supported version is 0.2.0. Please update the opaqueprompts package to a supported version.
+```
+
+If you see this, simply upgrade `opaqueprompts` with `pip install -U opaqueprompts` and then you should be able to continue using the package without issue.
+
+### Missing Version Header
+
+The logic to gracefully handle version mismatch was not added to the `opaqueprompts` package until version 0.1.0. As such, if you are using an older version of `opaqueprompts`, you may see the following error:
+
+```
+Client-Version header not set, please ensure this request was sent using opaqueprompts version >= 0.1.0
+```
+
+If you see this, make sure to update your `opaqueprompts` package to the latest version per the instructions in the "Version Mismatch" section.
