 **** How to create URL
 
+- Standart rules of URLs apply, if you know how to pass params in URL to any website, you don't even have to read this
+- Open some text editor
+- Paste in default URL: ~https://tools.treebrary.org/thread-watcher/feed.xml?~ (you can use plain HTTP if you want to)
+- Now you can append any of the supported parameters (which you can find in the above table):
+- For example if we want to be informed about threds with "cute" in their title
+  - ~q=cute~ which would make ~https://tools.treebrary.org/thread-watcher/feed.xml?q=cute~
+- If you want more than one param, separate with ~&~, for example:
+  - ~q=cute~ and ~q=pretty~ ~https://tools.treebrary.org/thread-watcher/feed.xml?q=cute&q=pretty~
+- Same is true for when you also want to specify ChoD
+  - ~https://tools.treebrary.org/thread-watcher/feed.xml?q=cute&q=pretty&chod=98~
+  - This will only notify you about threads that:
+    - Have ~cute~ or ~pretty~ in their title
+    - Are in the lowest 98% part of catalog (it's on position ~147/150 e.g. 3 threads before being bumped off)
+- Note that ~//~ are not special characters ~q=/general/~ will work as expected and match thread with "​/general​/" in it's title
+- Also note that regex is *NOT* supported for now, so something like ~q=rainbow*~ will only match threads with "rainbow[asterisk]"
+  in their title
