In order to share folders, your node needs to have the node attribute "tailfs:share".
In order to access shares, your node needs to have the node attribute "tailfs:access".
For example, to enable sharing and accessing shares for all member nodes:
"nodeAttrs": [
{
"target": ["autogroup:member"],
"attr": [
"tailfs:share",
"tailfs:access",
],
}]
Each share is identified by a name and points to a directory at a specific path. For example, to share the path /Users/me/Documents under the name "docs", you would run:
$ tailscale share add docs /Users/me/Documents
