 # Tips for new developers
 
+## Finding code
+
+There is find.sh script that ignores generated directories, finds code in subdirectories, and paginates with less. For example, finding how search cards is implemented:
+```
+cd wekan
+./find.sh js-search
+```
+When you run this, you see .jade template files where is search input box, and .js files where is the search code. CSS is in .styl files.
