+# How to make changes to status-go
+
+
+## Overview
+
+To make changes to status-go, the best approach is to first identify the issue/feature and the changes to be made directly in status-go.
+For any bugs we want to most likely write a failing test in status-go, and make sure that it passes, before we test on mobile.
+
+Once you are quite confident that the status-go code is ready to be tested on mobile, you can test it locally by running the following command:
+
+```
+env STATUS_GO_SRC_OVERRIDE={your-status-go-directory} make run-{android/ios}
+```
+
+This will recompile status-go and run status-mobile on your device with that updated status-go version.
+
+Once you have tested the status-go changes locally and you think it's ready for a PR:
+
+1) Create a PR in status-go
+
+2) Point your local status-mobile branch to that PR by running the script:
+
+```
+scripts/update-status-go.sh {status-go-branch-name}
+```
+
+This will update `status-go-version.json`
+
+Commit updated status-go-version.json and create a status-mobile PR
+
+Once both PRs have been approved and are good to merge, you can follow the [merge guidelines](./merging-pr-process.md)
