 * initial indexing is way faster, especially when the volume is on a network disk

+if you set `--no-hash`, you can enable hashing for specific volumes using flag `:c,ehash`
+
+
+## upload rules
+
+you can set upload rules using volume flags, some examples:
+
+* `:c,sz=1k-3m` sets allowed filesize between 1 KiB and 3 MiB inclusive (suffixes: b, k, m, g)
+* `:c,nosub` disallow uploading into subdirectories; goes well with `rotn` and `rotf`:
+* `:c,rotn=1000,2` moves uploads into subfolders, up to 1000 files in each folder before making a new one, two levels deep (must be at least 1)
+* `:c,rotf=%Y/%m/%d/%H` enforces files to be uploaded into a structure of subfolders according to that date format
+  * if someone uploads to `/foo/bar` the path would be rewritten to `/foo/bar/2021/08/06/23` for example
+  * but the actual value is not verified, just the structure, so the uploader can choose any values which conform to the format string
+    * just to avoid additional complexity in up2k which is enough of a mess already
+* `:c,lifetime=300` delete uploaded files when they become 5 minutes old
+
+you can also set transaction limits which apply per-IP and per-volume, but these assume `-j 1` (default) otherwise the limits will be off, for example `-j 4` would allow anywhere between 1x and 4x the limits you set depending on which processing node the client gets routed to
+
+* `:c,maxn=250,3600` allows 250 files over 1 hour from each IP (tracked per-volume)
+* `:c,maxb=1g,300` allows 1 GiB total over 5 minutes from each IP (tracked per-volume)
+
+
+## compress uploads
+
+files can be autocompressed on upload, either on user-request (if config allows) or forced by server-config
+
+* volume flag `gz` allows gz compression
+* volume flag `xz` allows lzma compression
+* volume flag `pk` **forces** compression on all files
+* url parameter `pk` requests compression with server-default algorithm
+* url parameter `gz` or `xz` requests compression with a specific algorithm
+* url parameter `xz` requests xz compression
+
+things to note,
+* the `gz` and `xz` arguments take a single optional argument, the compression level (range 0 to 9)
+* the `pk` volume flag takes the optional argument `ALGORITHM,LEVEL` which will then be forced for all uploads, for example `gz,9` or `xz,0`
+* default compression is gzip level 9
+* all upload methods except up2k are supported
+* the files will be indexed after compression, so dupe-detection and file-search will not work as expected
