 DESCRIPTION
     I got sick of imgur not working on mobile, so I built this
-    Images are resized to a max dimension of {3} px
+    Images are resized to a max dimension of {MAX_SIZE} px
     Don't use this for anything serious
 
 EXAMPLES
-    ~$ cat kitten.jpg | curl -F '{0}=@/dev/stdin' {1}
-       {1}/YXKV.jpg
-    ~$ firefox {1}/YXKV.jpg
+    ~$ cat kitten.jpg | curl -F '{POST}=@/dev/stdin' {URL}
+       {URL}/YXKV.jpg
+    ~$ firefox {URL}/YXKV.jpg
 
     Add this to your .bashrc:
 
-    alias {0}="curl -F '{0}=@/dev/stdin' {1}"
+    alias {POST}="curl -F '{POST}=@/dev/stdin' {URL}"
 
-    Now you can pipe directly into {0}!
+    Now you can pipe directly into {POST}!
