 ## Contributing / Development
 
-[Setup local development environment for OpenMRS SPA](https://o3-docs.openmrs.org/docs/frontend-modules/development)
+Check out the developer documentation [here](https://o3-docs.openmrs.org/docs/frontend-modules/development).
+
+This monorepo uses [yarn](https://yarnpkg.com/).
+
+To install the dependencies, run:
+
+```bash
+yarn
+```
+
+To start a dev server for the home app, run:
+
+```bash
+yarn start --sources 'packages/esm-home-app'
+```
+
+## Running tests
+
+To run all tests, run:
+
+```bash
+yarn turbo run test --filter=@openmrs/esm-home-app
+```
+
+To run a specific test file, run:
+
+```bash
+yarn turbo run test -- <test-file-name>
+```
+
+The above command will only run tests in the file or files that match the provided string.
+
+To generate a `coverage` report, run:
+
+```bash
+yarn turbo run coverage
+```
+
+By default, `turbo` will cache test runs. This means that re-running tests without changing any of the related files will return the cached logs from the last run. To bypass the cache, run tests with the `force` flag, as follows:
+
+```bash
+yarn turbo run test --force
+```
+
+## Troubleshooting
+
+If you notice that your local version of the application is not working or that there's a mismatch between what you see locally versus what's in [dev3](https://dev3.openmrs.org/openmrs/spa), you likely have outdated versions of core libraries. To update core libraries, run the following commands:
+
+```bash
+# Upgrade core libraries
+yarn up openmrs@next @openmrs/esm-framework@next
+
+# Reset version specifiers to `next`. Don't commit actual version numbers.
+git checkout package.json
+
+# Run `yarn` to recreate the lockfile
+yarn
+```
