 This is used to create sets of pre-generated keyshares. These are used in some of the `entropy-tss`
 tests to speed up the test by not needing to run a distributed key generation during the test.
 
-Since keyshares are linked to the identities of the holders, and the initial signer set is selected
-randomly during the test, there is one keyshare set generated per possible combination of initial
-signers.
-
-Since we have 4 nodes, and 3 signers, we refer to each set by the name of the node who is **not** in
-the signer set (which is the one who will act as the relayer node).
-
-So set 'alice' consists of ['bob', 'charlie', 'dave'] and set 'bob' consists of ['alice', 'charlie',
-dave'], etc.
-
-There are also different keyshare sets for 'test' or 'production' parameters used by Synedrion. Test
+There are different keyshare sets for 'test' or 'production' parameters used by Synedrion. Test
 parameters are less secure but mean that the protocols run much faster.
