+## When things go wrong
+
+After Borg runs, it indicates whether it succeeded via its exit code, a
+numeric ID indicating success, warning, or error. borgmatic consumes this exit
+code to decide how to respond. Normally, a Borg error results in a borgmatic
+error, while a Borg warning or success doesn't.
+
+But if that default behavior isn't sufficient for your needs, you can
+customize how borgmatic interprets [Borg's exit
+codes](https://borgbackup.readthedocs.io/en/stable/usage/general.html#return-codes).
+For instance, to elevate Borg warnings to errors, thereby causing borgmatic to
+error on them, use the following borgmatic configuration:
+
+```yaml
+borg_exit_codes:
+   - exit_code: 1
+     treat_as: error
+```
+
+Be aware though that Borg exits with a warning code for a variety of benign
+situations such as files changing while they're being read, so this example
+may not meet your needs. Keep reading though for more granular exit code
+configuration.
+
+Here's an example that squashes Borg errors to warnings:
+
+```yaml
+borg_exit_codes:
+   - exit_code: 2
+     treat_as: warning
+```
+
+Be careful with this example though, because it prevents borgmatic from
+erroring when Borg errors, which may not be desirable.
+
+<span class="minilink minilink-addedin">New in Borg version 1.4</span> Borg
+support for [more granular exit
+codes](https://borgbackup.readthedocs.io/en/1.4-maint/usage/general.html#return-codes)
+means that you can configure borgmatic to respond to specific Borg conditions.
+See the full list of [Borg 1.4 error and warning exit
+codes](https://borgbackup.readthedocs.io/en/1.4.0b1/internals/frontends.html#message-ids).
+The `rc:` numeric value there tells you the exit code for each.
+
+For instance, this borgmatic configuration elevates all Borg backup file
+permission warnings (exit code `105`)—and only those warnings—to errors:
+
+```yaml
+borg_exit_codes:
+   - exit_code: 105
+     treat_as: error
+```
+
+The following configuration does that *and* elevates backup file not found
+warnings (exit code `107`) to errors as well:
+
+```yaml
+borg_exit_codes:
+   - exit_code: 105
+     treat_as: error
+   - exit_code: 107
+     treat_as: error
+```
+
+If you don't know the exit code for a particular Borg error or warning you're
+experiencing, you can usually find it in your borgmatic output when
+`--verbosity 2` is enabled. For instance, here's a snippet of that output when
+a backup file is not found:
+
+```
+/noexist: stat: [Errno 2] No such file or directory: '/noexist'
+...
+terminating with warning status, rc 107
+```
+
+The exit status to use in that case would be `107` if you want to configure
+borgmatic to treat it as an error.
