+Terminal program for converting between bases.  
 
 To build, run `make`. To install, build and run `sudo make install`.  To
 uninstall, run `sudo make uninstall`.
 
-Run `hexc {operator} {string1 string2 string3...}` to produce a converted string or series of strings.  
+Run `hexc {operator} {string1 string2 string3...}` or `hexc {-i[input base size] -o[output base size] {string1 string2 string3...}` to produce a converted string or series of strings.  
 
 The operators are as follows:

+### Examples
 ```
 ~$ hexc -bd 10101 111
 10101 -> 21
 111 -> 7
-~$ hexc -hb 3b9ac9ff ABC123
-3B9AC9FF -> 00111011100110101100100111111111
-ABC123 -> 101010111100000100100011
+~$ hexc -i8 -o16
+312 -> CA
 ```  
 
 ### To-do
-* Implement conversion to and from ASCII
-* Implement the ability to feed text files as input
-* Figure out some better way to implement HexToBin (I know it's ugly)
-* Raise limit on BinToDec and HexToDec
+* Fix bug of inaccurate output when converting very large numbers
