 Usage
 -----
 
-1. Drag and drop archive files to `arc_unpacker`.
-2. Drag and drop non-archive files onto `file_decoder`.
-3. Some formats need additional switches in order to unpack correctly.
-   These can be found out using `--help`.
+1. See `--help` to list all the formats.
+2. Choose one of the formats.
+3. Provide parameters it requires (`--help --fmt=FMT` to inspect them). Most of
+   them work out-of-the-box.
+4. Finally, run the program.
+
+There is also auto-detection feature (meaning you can drag'n'drop the files
+on the executable), but it may not work occasionally, or refuse to work
+completely if the format requires additional parameters. So for now use it
+wisely. In the long run, this is going to be improved in #17.

-If the game isn't listed above, there is still a small chance that the files
-can be extracted nonetheless. Note that some archives provide no way to verify
-correctness of the extracted files, which means that there can be false
-positives and you might get garbage files. That shouldn't happen with any of
-the games listed above, though.
