-  * Verify m-of-n signatures by given group are present for directory
+* sig verify [-g,--group=<group>] [-t,--threshold=<N>] [-r,--ref=<ref> ] [-d,--diff=<branch>]
+  * Verify m-of-n signatures by given group are present for a git repo or ref
 * sig add
-  * Add signature to manifest for this directory
-* sig manifest
-  * Generate hash manifest for this directory
+  * Add signature to this git ref
 * sig fetch [-g,--group=<group>]
   * Fetch key by fingerprint. Optionally add to group.

-### Detached
-
-This method verifies the state of this folder was signed exactly as-is by one
-or more authors.
-
-## Behavior
-
-If 'threshold' is specified, then that number of signatures must be present.
-
-If 'group' is specified, all signatures must be by keys that belong to a
-defined gpg alias group.
-
 ### Assumptions
-  - Single sig mode: Folder contents controlled by signer
-  - Multi-sig mode: Folder contents verified by multiple signers
-  - Multi-sig group mode: Folder contents approved by specified individuals
-  - Hashing scheme for respective backend is not broken
-    - Git: sha1
-    - Detached: sha256
+  - Single sig mode: Repo contents controlled by signer
+  - Multi-sig mode: Repo contents verified by multiple signers
+  - Multi-sig group mode: Repo contents approved by specified individuals
+  - Hashing scheme for respective backend is not broken: (sha256)

-#### Verify 1 signature via Detached and Git methods
+#### Verify at least one signature is present with a known key
 
 ```
 sig verify
 ```
 
-#### Verify 2 unique signatures via Detached and Git methods
+#### Verify 2 unique signatures from known keys
