 # BrainGlobe Workflows
 
 `brainglobe-workflows` is a package that provides users with a number of out-of-the-box data analysis workflows employed in neuroscience, implemented using BrainGlobe tools.
+
+These workflows represent the most common use-cases and are meant to be easy to reuse. They also serve as an example of how to combine several BrainGlobe tools  (possibly together with other tools) to achieve a goal, such as whole brain cell detection and atlas registration.
+
 You can view the [full documentation for each workflow](https://brainglobe.info/documentation/brainglobe-workflows/index.html) online.
 You can also find the documentation for the backend BrainGlobe tools these workflows use [on our website](https://brainglobe.info/).
 
-At present, the package offers the following workflows:

-## Secondary purposes of brainglobe-workflows, for developers
+Additionally, this repository provides functionalities to support code developers. See [Developers documentation](#developers-documentation) for further details.
 
-We also use these workflows to support code development. We do this by regularly benchmarking the time they take to complete to ensure performance is stable as the code changes.
-* Developers can install these benchmarks locally via `pip install .[dev]`. By executing `asv run`,  the benchmarks will run with default parameters on a small dataset that is downloaded from [GIN](https://gin.g-node.org/G-Node/info/wiki). See [the asv docs](https://asv.readthedocs.io/en/v0.6.1/using.html#running-benchmarks) for further details on how to run benchmarks.
-* Developers can also run these benchmarks on  data available locally, by specifying the relevant paths in an input configuration file (JSON file).
-* We additionally run and benchmark the workflows locally on a internal desktop machine with large example datasets. These benchmarks are run periodically and the results are made publicly available.

 `brainglobe-workflows` is built using BrainGlobe tools, and it will automatically fetch the tools that it needs and install them into your environment.
 Once BrainGlobe version 1 is available, this package will fetch all BrainGlobe tools and handle their install into your environment, to prevent potential conflicts from partial-installs.
