 ## Setup
 
-To setup using the nightlies use:
+Setup a DaVinci version:
 
 ```bash
-lb-run --nightly=lhcb-master/Today DaVinci/v60r3 bash
+lb-run DaVinci/<version> bash
 ```
 
+Here `<version>` can also be `latest`, in which case the latest release is picked up.
+One can also setup DaVinci using the nightly builds:
+
+```bash
+lb-run --nightly=lhcb-head/<slot_number> DaVinci/HEAD bash
+```
+
+Here `<slot_number>` can be looked up at the nightlies [webpage](https://lhcb-nightlies.web.cern.ch/nightly/).
+The `<slot_number>` can also take values like `Today` or `Yesterday`, where either today's or yesterday's nightly
+build can be picked up accordingly.
+
 Alternatively, if you need to make non-trivial changes build your own [stack](https://gitlab.cern.ch/rmatev/lb-stack-setup) for DaVinci (WARNING: Takes a very long time to build and is not suited to virtual machines like lxplus)

 Objectives:
 
-- Configuring the Decay Tree Fitter algorithm (`DecayTreeFitterAlg`) to build a relation table i.e. map between the candidate and the refitted candidate.
-- Usage of the relations table and `ThOr` functor (e.g. `F.MAP_INPUT(func, RelTable`) to get refitted information of the candidate.
-- Defining different instances of DTF algorithm with mass constraints, primary vertex constraint.
+- Usage of Decay Tree Fitter (`DecayTreeFitter`) to store refitted quantities.
