 At the same time, `mamba` utilizes the same command line parser, package installation and deinstallation code and transaction verification routines as `conda` to stay as compatible as possible.
 
-Mamba is part of a bigger ecosystem to make scientific packaging more sustainable. You can read our [announcement blog post](https://medium.com/@QuantStack/open-software-packaging-for-science-61cecee7fc23).
-The ecosystem also consists of `quetz`, an open source `conda` package server and `boa`, a fast `conda` package builder.

 ### `repoquery`
 
 To efficiently query repositories and query package dependencies you can use `mamba repoquery` or `micromamba repoquery`.

 See the [repoquery documentation](https://mamba.readthedocs.io/en/latest/user_guide/mamba.html#repoquery) for details.
 
 ### Installing lock files
 
-`micromamba` can be used to install lock files generated by [conda-lock](https://conda.github.io/conda-lock/) without having to install `conda-lock`. Simply invoke e.g. `micromamba create -n my-env -f conda-lock.yml` with an environment lockfile named `*-lock.yml` or `*-lock.yaml`.

 ### setup-micromamba (setup-miniconda replacement)
 
 [setup-micromamba](https://github.com/marketplace/actions/setup-micromamba) is a replacement for [setup-miniconda](https://github.com/marketplace/actions/setup-miniconda) that uses `micromamba`.
+
 It can significantly reduce your CI setup time by:
 
 - Using `micromamba`, which takes around 1 s to install.
 - Caching package downloads.
 - Caching entire `conda` environments.
 
-## micromamba
-
-`micromamba` is a small, pure-C++ reimplementation of `mamba`/`conda`. It strives to be a full replacement for `mamba` and `conda`. As such, it doesn't use any `conda` code (in fact it doesn't require Python at all).
-
-See the [documentation on `micromamba`](https://mamba.readthedocs.io/en/latest/user_guide/micromamba.html) for details.
