+# Make changes to DPLSH
+## When to use
+When for example the `kubectl` version need updating
+
+## Make the change
+
+1. Go to the DPLSH directory and make the necessary changes on a new branch
+2. Build DPLSH locally by running `IMAGE_URL=dplsh IMAGE_TAG=someTagName task build`
+3. Test that it works by running `DPLSH_IMAGE=dplsh:local ./dplsh` and running what ever commands need to be run to test that the change has the desired effect
+4. Check what version DPLSH is at here: https://github.com/danskernesdigitalebibliotek/dpl-platform/releases
+5. Push the branch, have it review and merge it into `main`
+6. Push a new tag to `main`. The tag should look like this: `dplsh-x.x.x`. (If in doubt about what version to bump to; read this: https://semver.org/)
+7. Wait for main to automically build and release the new version
+8. Go to your main branch, enter the `/infrastructure` directory and run `../tools/dplsh/dplsh.sh --update`.
+
+You are done and have the newest version of DPLSH on your machine.
