 ## Differences from Python version
 
-
 Templating for Alert messages has been updated. In the Python version, `str.format(...)` was used with certain keys passed in that could be used to format messages. In the Go version, we use a struct, `AlertNotice` defined in `alert.go` and the built in Go templating format. Eg.
 
 minitor-py:
 ```yaml
 alerts:
-  log_command:
-    command: ['echo', '{monitor_name}']
-  log_shell:
+  log:
     command: 'echo {monitor_name}'
 ```
 
 minitor-go:
 ```yaml
 alerts:
-  log_command:
-    command: ['echo', '{{.MonitorName}}']
-  log_shell:
+  log:
     command: 'echo {{.MonitorName}}'
 ```
 
-Finally, newlines in a shell command don't terminate a particular command. Semicolons must be used and continuations should not.
+For the time being, legacy configs for the Python version of Minitor should be compatible if you apply the `-py-compat` flag when running Minitor. Eventually, this flag will go away when later breaking changes are introduced.
 
-minitor-py:
-```yaml
-alerts:
-  log_shell:
-    command: >
-      echo "line 1"
-      echo "line 2"
-      echo "continued" \
-        "line"
-```
+## Future
 
-minitor-go:
-```yaml
-alerts:
-  log_shell:
-    command: >
-      echo "line 1";
-      echo "line 2";
-      echo "continued"
-        "line"
-```
-
-## To do
-There are two sets of task lists. The first is to get rough parity on key features with the Python version. The second is to make some improvements to the framework.
-
-Pairity:
-
-  - [x] Run monitor commands
-  - [x] Run monitor commands in a shell
-  - [x] Run alert commands
-  - [x] Run alert commands in a shell
-  - [x] Allow templating of alert commands
-  - [x] Implement Prometheus client to export metrics
-  - [x] Test coverage
-  - [x] Integration testing (manual or otherwise)
-  - [x] Allow commands and shell commands in the same config key
-
-Improvement (potentially breaking):
+Future, potentially breaking changes
 
   - [ ] Implement leveled logging (maybe glog or logrus)
-  - [ ] Consider switching from YAML to TOML
   - [ ] Consider value of templating vs injecting values into Env variables
-  - [ ] Consider dropping `alert_up` and `alert_down` in favor of using Go templates that offer more control of messaging
   - [ ] Async checking
-  - [ ] Use durations rather than seconds checked in event loop
   - [ ] Revisit metrics and see if they all make sense
+  - [ ] Consider dropping `alert_up` and `alert_down` in favor of using Go templates that offer more control of messaging (Breaking)
+  - [ ] Use durations rather than seconds checked in event loop (Potentially breaking)
