 ## ptth_server instance data
 
 These are captured during process start and then don't change. They're kinda
 like metrics, but static.
 
-- Machine ID
-- Git version (if possible)
-- Server ID

+## Todo
+
+- ( ) Add `find`-like API endpoint on servers
+- ( ) Implement sync for one file
+- ( ) Implement sync for one dir
+- ( ) Implement recursive sync
+
+## Find endpoint
+
+Retrieves `stat` info recursively for all files in a dir.
+
+Also, add mtime. That will make the syncer client a little better.
