+`jq` is a very simple command-line json parser. It can read data in json format and return specific values.
 
 Its most important options are `-e` and `-a`. `-e` extracts the value of a given key from a json array or object:
 
     # Find the object with key "title" from a json object stored in the file "json"
-    jshon -e 'title' < 'json'
+    jq '.title' < 'json'
 
 The `-a` option maps all remaining options across the currently selected element. It has to be combined with other options, for example the `-e` option. 
 
     # Find the names of all elements stored in the json object in file "json"
-    jshon -a -e 'name' < 'json'
+    jq '[].name' < 'json'
