Importing from bibtex or zotero
Many users will want to import a library from a bibtex file
that another program such as
jabref will have exported. These programs usually have a
file that points to a path
where the document file can be found.
To import such a library you can use a provided script originally
zotero which is, however, general enough to work
for other programs too.
To install this script you can install the project papis-zotero and follow the instructions therein to import a bibliography file into papis.
You can also take a look at the zotero2papis project in order to see a different workflow and different implementation of a converter script. This blogpost explains the workflow using papis with zotero and SyncThing.
