 The general processing workflow for almost any crosslink search is depicted [here](workflows/general_wf.png).
 
-*The provided workflows also require the installation of [MS Amanda](https://dx.doi.org/10.1021/pr500202e) which can be downloaded [here](https://ms.imp.ac.at/?action=ms-amanda).
+For MS2 searches (CID, ETD, HCD, stepped HCD) it can also be beneficial to employ the [IMP MS2 Spectrum Processor]() node, an example workflow for Proteome Discoverer 3.0 is given here: [pdAnalysis](https://github.com/hgb-bin-proteomics/MSAnnika/raw/master/workflows/PD3.0/DSSO_IMP_MS2.zip) / [zip](https://github.com/hgb-bin-proteomics/MSAnnika/raw/master/workflows/PD3.0/DSSO_IMP_MS2.zip)

+## Support for MGF and timsTOF Data
+
+The following MS Annika versions support MGF\* and timsTOF\*\* data input:
+- Proteome Discoverer 3.1: [MS Annika 2.0 v2.2.1](https://github.com/hgb-bin-proteomics/MSAnnika/releases/tag/v2.2.1)
+- Proteome Discoverer 3.0: [MS Annika 2.0 v1.1.4fix](https://github.com/hgb-bin-proteomics/MSAnnika/releases/tag/v1.1.4fix)
+- Proteome Discoverer <=2.5: [MS Annika 1.0 v1.0.0](https://github.com/hgb-bin-proteomics/MSAnnika/releases/tag/v1.0.0)\*\*\*
+
+\*MS Annika 2.0 only supports MS2 search for MGF files since MGF files don't contain sufficient MS3 information.  
+\*\*requires installation of the Bruker Ion Mobility reader.
