 ### installation
-`make install` or `raco pkg install`
+`make build && make install` will build and copy `tt` binary into `$PREFIX/bin`.
+
+### configuration
+Put your `<nick>` and `<uri>` into `~/.tt/me`. For example, mine is:
+
+```
+$ cat ~/.tt/me
+xandkar https://xandkar.net/twtxt.txt
+```
+It will be used to fill the `User-Agent` header, so that others can tell you're
+reading their twtxts and perhaps read yours. This isn't strictly necessary and
+if omitted, you'll stay anonymous.
 
 ### usage
-`tt (FOLLOW-FILE)`
+Download feeds from the Internet:
+`tt d (FOLLOW-FILE)`
+
+Read your timeline:
+`tt r (FOLLOW-FILE)`
+
+`FOLLOW-FILE` contains lines with space-separated nick and twtxt.txt URI, like:
+
+```
+xandkar https://xandkar.net/twtxt.txt
+```
+
+See the rest of the usage options:
+`tt -h`
+
+`tt <command> -h`

+
+### LWW downloads
+Downloaded timelines are stored in `~/.tt/cache/<SHA1_OF_URI>`, but no attempt
+is made to preserve the previously-downloaded messages - each download
+overrites the previous. One of the implications is that authors can edit/delete
+history without you noticing.
