+# Frequently Asked Questions
+
+### I'm not seeing the latest `@openmrs/esm-framework`. How do I update the dependency?
+
+In a repository using Yarn:
+
+```
+yarn upgrade @openmrs/esm-framework openmrs  // to upgrade
+git checkout package.json  // to reset the version specifiers to 'next'
+```
+
+### How do I keep my local dev server up to date?
+
+Just pull the repository you want to work on and run `yarn` or `npm install`.
+That will install the latest dependencies, which includes `openmrs`, which is
+the tool that runs the dev server.
+
+### How do I find out where the code I need to work on is?
+
+There is no simple correlation between packages and pages and content.
+
+The first thing to check is the [list of repositories](http://o3-dev.docs.openmrs.org/#/main/map?id=repositories-you-should-know-octocat)
+and their descriptions. There aren't very many, so it's likely you can
+figure out what you're trying to work on just by looking at the list.
+
+If that doesn't work out, another trick is to clone all of the repositories
+and then run `grep` across them to look for something you expect to find—
+e.g. a piece of text from the UI.
+
+If you have done both of the above things and still haven't found the
+code you're looking for, feel free to ask in the
+[#openmrs-helpme](https://openmrs.slack.com/archives/C02UNMKFH8V) channel
+on Slack.
