+# How to grow an ARC - an example
+

+
+Data Science and Management & Cluster of Excellence on Plant Sciences (CEPLAS), University of Cologne
+
+*This work is supported by CEPLAS, funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) within Germany´s Excellence Strategy – EXC-2048/1 – project ID 390686111.*
+
+This example uses the command line.  
+It shows the process of growing an ARC to be used in demos and also while trying options and arguments of the [ARC Commander](https://github.com/nfdi4plants/arcCommander).  
+Please note, this is work in progress and the ARC is example ARC is not completed yet.  
+Successively, it is planned to add and use more features.  
+
+## Used OS and ARC Commander version  
+
+Used for this example:  
+> arc version: v0.5.0  
+> macOS Ventura 13.5.1  
+
+## Prepare the ARC  
+
+- Decide on and prepare:  
+> "NAME" and/or "ARC_NAME" of the investigation  
+> Here, used for both: **Grow-an-ARC_Example**
+
+- create an empty project in the HUB (no README), name: "ARC_NAME"  
+- create an empty directory on the local device (Mac) with the same name, name: "ARC_NAME"  
+- go into this directory  
+
+### Initiate the ARC locally
+
+```bash
+arc init
+```  
+
+### Create the investigation
+
+```bash
+arc i create -i ARC_NAME   
+``` 
+
+## isa.investigation - general metadata  
+
+- More information can be added later.
+- Decide and prepare:  
+> "TITLE" of the investigation  
+> "DESCRIPTION" of the investigation  
+
+```bash
+arc investigation update --identifier "ARC_NAME" --title "TITEL" --description "DESCRIPTION"  
+```
+
+## isa.investigation contact person(s) metadata  
+
+### Adding a contact person for the investigation - example
+
+```bash
+arc i person register -l Schrader -f Andrea --email andrea.schrader@uni-koeln.de --address "50674 Cologne, Germany" --affiliation "Data Science and Management & Cluster of Excellence on Plant Sciences (CEPLAS), University of Cologne" --roles "contact person; data-curator; leads investigation; designs experiments; supervisor; performs experiments" --rolestermsourceref "SCORO; SCORO; SCORO; SCORO; SCORO; SCORO" --orcid "0000-0002-3879-7057"  
+```
+
+### Adding a second contact person - with placeholders and example ontology entries  
+
+I am using here my ORCID iD as e.g. "0000-0000-0000-0000" will cause an error in the validation.  
+Of course, the ORCID iD of PERSON2 should be used here.
+
+```bash
+arc i person register -l LASTNAME_PERSON2 -f FIRSTNAME_PERSON2 -m MIDNAME_PERSON2 --email person2@uniX.de --address "XXXXX CITY, COUNTRY" --affiliation "AFFILIATION_PERSON2" --roles "principal investigator; leads investigation; designs experiments; supervisor" --rolestermsourceref "SCORO; SCORO; SCORO; SCORO" --orcid "0000-0002-3879-7057"  
+```
+
+## isa.investigation publication(s) metadata
+
+### Adding a publication - Example with placeholders and example ontology entries
+
+```bash
+arc i publication register --doi "10.XXXX/pp.XXX.XXXXXX" -p "PUBMED_ID" --authorlist "Author1; Author2; Author3; Author4; Author5" --title "PUBLICATION_TITLE" --status "published" --statustermaccessionnumber "http://www.ebi.ac.uk/efo/EFO_0001796" --statustermsourceref "EFO"  
+```
+
+- switched manually statustermaccessionnumber and statustermsourceref in isa.investigation.xlsx which are interchanged due to a bug (already reported)  
+- added manually the ontology source reference information as no option is available for this yet:  
+
+Term Source Name |	EFO	| SCORO
+---|---|---
+Term Source File |	http://www.ebi.ac.uk/efo/efo.owl	| http://purl.org/spar/scoro
+Term Source Version	| 3.49.0 | 1.9.1
+Term Source Description	| Experimental Factor Ontology |	Scholarly Contributions and Roles Ontology
+
+### Adding a second publication
+
+As above but ontology reference information do not need to be entered in duplicates.
+
+## Connect the ARC with the HUB 
+
+Connect the local ARC with the HUB "project" and sync changes
+
+- Prepare a TOKENSTRING (personal access token (e.g. like here: https://github.com/nfdi4plants/arcCommander/discussions/157))
+- replace TOKENSTRING,YourGitLabNAME and ARC_NAME below
+
+```bash
+arc sync -r https://oauth2:TOKENSTRING@git.nfdi4plants.org/YourGitLabNAME/ARC_NAME -m "Initiated an ARC, added investigation metadata added manually the ontology source reference information as no option is available for this so far."
+```
+
+## Add a README, a LICENCE and a .gitignore file
+
+Here: A template README has been added here as TEMPLATE_README.md.  
+> When this is used, it needs to be named "README.md".  
+
+Here: A CC-BY 4.0 license has been added.  
+Here: An initial .gitignore file has been added with the entry ".DS_Store" for macOS.  
+
+### Sync with the HUB
+
+```bash
+arc sync -m "Added a README template, .gitignore for macOS and a CC-BY 4.0 licence file."
+```  
+
+## Only for this Grow-an-ARC_Example - add the README.md which contains the procedure described here.
+
+```bash
+touch README.md
+```
