-`aiida-aimall`'s main draw is that it enables automation to link the outputs of standard computational chemistry software directly to an AIMAll calculation. A list of provided workflows is shown in Table 1. The software with the most robust implementation is Gaussian software,[@gaussian] as Gaussian already has an implemented `aiida` package. Other computational chemistry software like ORCA can be run through the `QMToAIMWorkchain`, which uses `aiida-shell` to run software than can be run through the command line. If .molden or .cp2k output formats are available, one could alternatively use these to generate the needed .wfx files for AIMAll, and automatically run AIMAll through the `GenerateWFXToAIMWorkchain`.

 ## Controllers to limit computer burden when running large numbers of jobs
-The last main contribution of `aiida-aimall` is through the definition of `FromGroupSubmissionController`s from the `aiida-submission-controller` package. These controllers limit active processes and can be used together as
-demonstrated in (the example notebook) to automate the entire `SubstituentParameterWorkchain`. These use a number of `Workchains` developed just for their use in these controllers. The process flows as `SmilesToGaussianController` -> `AIMAllReorController` -> `GaussianController` -> `AIMAllController`. The latter two controllers can also be seen and used as general use controllers wrapping `GaussianCalculations` and `AimqbCalculations`
