+# Carreta ID
+Random user-friendly id for distubuted system for personal data.
+## Examples
+
+- `123` : shortest version
+- `456-789` : default size, still user freindly and sufficient randomness (for personal data)
+- `abc-def-ghj` : long version. alphabets except i, l and o are also valid　
+## Specs
+### Characters
+
+
+
+## Perpose
+When I considering implementing IDs for users(not for internal system) to specify items, such as GitHub commit hashes or issue numbers, the following issues arose.
+
+- Sequential numbers like Git issues are difficult to implement in distributes systems because collitions are unavoidable.
+- Random number like UUID is too long for users
+- Short random number like 7-digit commit hash seems good but is is not standardized specification.
+
+So I decided to make my own ID specifications.
