+### Performing a clean reinstall
+
+Run the one-line installer script with the `--reinstall-clean` parameter to perform a clean reinstall of the
+Netdata Agent. This will wipe all existing configuration and historical data, but can be useful sometimes for
+getting a badly broken installation working again. Unlike the regular `--reinstall` parameter, this may use a
+different install type than the original install used.
+
+If you used any [optional
+parameters](/packaging/installer/methods/kickstart.md#optional-parameters-to-alter-your-installation) during initial
+installation, you need to pass them to the script again during reinstallation. If you cannot remember which options you
+used, read the contents of the `.environment` file and look for a `REINSTALL_OPTIONS` line. This line contains a list of
+optional parameters.
+
+```bash
+wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-kickstart.sh --reinstall-clean
+```
+
+### Changing the install type of an existing installation
+
+The clean reinstall procedure outlined above can also be used to manually change the install type for an existing
+installation. Without any extra parameters, it will automatically pick the preferred installation type for your
+system, even if that has changed since the original install. If you want to force use of a specific install type,
+you can use the `--native-only`, `--static-only`, or `--build-only` parameter to control which install type gets
+used, just like with a new install.
+
+When using the `--reinstall-clean` option to change the install type, you will need to manually preserve any
+configuration or historical data you want to keep. The following directories may need to be preserved:
+
+- `/etc/netdata` (`/opt/netdata/etc/netdata` for static installs): For agent configuration.
+- `/var/lib/netdata` (`/opt/netdata/var/lib/netdata` for static installs): For claiming configuration.
+- `/var/cache/netdata` (`/opt/netdata/var/cache/netdata` for static installs): For historical data.
+
+When copying these directories back after the reinstall, you may need to update file ownership by running `chown
+-R netdata:netdata` on them.
+
