 ### Development
 
-Once the general idea is tied down, you can open a pull request with your code.
-We encourage to open a pull request early on.
+Once the general idea is tied down, you can open a pull request (towards the `main` branch) with your code.
+We encourage to open a pull request early on, to incorporate review comments from the beginning.
 
 For development, we recommend _test driven development_, that is writing tests and the features at the same time supporting each other.

 Python reference implementation of the [Laboratory Experiment COntrol (LECO) protocol](https://github.com/pymeasure/leco-protocol).
 
-The [reviewed branch](https://github.com/pymeasure/pyleco/tree/reviewed) contains reviewed code, which does not yet contain all necessary modules and classes.
-Development happens in the [main](https://github.com/pymeasure/pyleco/tree/main) branch.
-
 **Note**: LECO is still under development, such that the code and API might change.
 The LECO protocol branch [pyleco-state](https://github.com/pymeasure/leco-protocol/tree/pyleco-state) contains the assumptions used in this project, which are not yet accepted into the LECO main branch.
 See this [documentation](https://leco-laboratory-experiment-control-protocol--69.org.readthedocs.build/en/69/) for the LECO definitions including these assumptions.
