Switch your Timbre namespace imports:
What about all the Timbre logging calls in your code?
You've got two choices-
#### 2a. Redirect Timbre output to Telemere
Add [`taoensso.telemere.timbre/timbre->telemere-appender`](https://cljdoc.org/d/com.taoensso/telemere/CURRENT/api/taoensso.telemere.timbre#timbre->telemere-appender) as a Timbre appender. It'll redirect Timbre's output to Telemere.
In this case you may want to disable all your other Timbre appenders, and all your Timbre filtering.
#### 2b. Change your ns imports
The [`taoensso.telemere.timbre`](https://cljdoc.org/d/com.taoensso/telemere/CURRENT/api/taoensso.telemere.timbre) namespace contains a shim of most of Timbre's API so you can switch your Timbre namespace imports:

In this case your Timbre appenders and filtering will be ignored.
Feel free to keep using this shim API **as long as you like**, there's no need to rewrite any of your existing code unless you specifically want to use features that are only possible with Telemere's [signal creators](./1-Getting-started#create-signals), etc.
