+### Publishing a new copy of our fork
+
+Note that for versioning we should retain the original OSS version and add a suffix for any customisations we make.
+
+* If you've just pulled in downstream changes then you'd publish a new suffixed version e.g. if the OSS version is `0.21.4` then we'd use `0.21.4-1`.
+* If you've made a new customisation then increment the suffixed version e.g. if the current version is `0.21.4-1` then you'd use `0.21.4-2` next.
+
+To publish this Atlassian fork run the following commands:
+
+1. `atlas packages permission grant -u {{staffid}}` to grant publishing writes within Artifactory
+2. `yarn preconstruct build` to generate the dist
+3. `cd packages/cli/` to navigate into the CLI workspace
+4. `npm version {{version}}` to increment the version
+5. `npm publish` to upload to artifactory
+6. Discard the git diff generated for `yarn.lock` and `package-lock.json`.
+7. Commit the updated version number within `packages/cli/package.json`.
