-`SQUARE` holds the square - without spaces or anything else. Just all letters one after another.
+`SQUARE` holds the raw square - without spaces or anything else. Just all letters one after another.
 
 
 At the bottom, the `letters` variable holds all available letters from the `SQUARE` and their amounts.

+Example
+-------
+
+For a given magic word square puzzle, i.e. letters and number of letters are given, e.g.:
+
+```
+AAACCC
+CEEEEE
+EEEIIL
+LMRRRR
+RRSSSS
+TTTTUU
+```
+
+You should write it into the `SQUARE` variable like this:
+
+```
+SQUARE="AAACCCCEEEEEEEEIILLMRRRRRRSSSSTTTTUU"
+```
+
+If you run the script, the output should look like this after a few seconds:
+
+```
+Word length: 6
+{'C': 4, 'L': 2, 'R': 6, 'S': 4, 'I': 2, 'A': 3, 'E': 8, 'U': 2, 'M': 1, 'T': 4}
+Diag candidate: A
+Diag candidate: M
+1248 candidates.
+.------.
+|CIRCLE|
+|ICARUS|
+|RAREST|
+|CREATE|
+|LUSTRE|
+|ESTEEM|
+'------'
+```
+
+First, it determines the length per word from the `SQUARE` string.
+
+Then it lists all letters and their amount.
+
+"Diag candidate" means, that letter has an odd amount and is on the diagonal.
+
+"1248 candidates." means it found 1248 words in the dictionary which could fit into our square.
+
+After a few seconds, if a solution was found, it is displayed as the solved square.
