-* Get puush from here: http://b3.blha303.com.au/puush-linux/files/puush
-* Copy 'puush' to /usr/bin.
-* Use it with `puush file.name`. 
+* Get curl if you don't have it already. Most package managers have it as `curl` (apt-get install curl, yum install curl), or check this page: http://curl.haxx.se/download.html
+* Get puush from here: https://github.com/blha303/puush-linux/raw/master/puush
+* Copy 'puush' to /usr/local/bin, and use `chmod +x /usr/local/bin/puush`.
+* For uploading a file, use `puush file.ext`.
+* For uploading from stdin, use `cat file.ext | puush - ext`.
 
-You'll need to set up an environment variable, PUUSH_API_KEY. You can do this per-session with `export PUUSH_API_KEY="apiKeyHere"`, or by putting that command in `~/.bashrc`.
