 ### Custom Counting Strategies
 
-The counting logic is fully pluggable. The default three-type system works for most cases, but you can override the counting methods (`count_vote`, `tally_succeeded`, `quorum_reached`) to implement alternative strategies such as fractional voting, weighted quorum relative to total supply, or NFT-based voting schemes. The `counting_mode()` method returns a symbol identifying the active strategy, which UIs can use for display purposes.

 If you are using the Fungible or Non-Fungible token from this library, the **Votes extension** handles all of this automatically. You only need to enable the extension — no manual integration required. See [Fungible Token](/stellar-contracts/tokens/fungible/fungible) or [Non-Fungible Token](/stellar-contracts/tokens/non-fungible/non-fungible).

-## Free Functions
-
-In addition to the trait, the module exports free functions for lower-level use:
-
-| Function | Description |
-|----------|-------------|
-| `transfer_voting_units(e, from, to, amount)` | Updates voting units on balance changes. `from`/`to` are `Option<&Address>` for mint/burn. |
-| `get_voting_units(e, account)` | Returns the raw voting units (not delegated votes) for an account. |
-| `get_checkpoint(e, account, pos)` | Returns a specific checkpoint by position index. |
-| `num_checkpoints(e, account)` | Returns the number of checkpoints for an account. |
-| `delegate(e, account, delegatee)` | Delegates voting power. Requires authorization from `account`. |
