 Instead of using evironment variables,
     the claimer will get the list of application addresses from Redis,
     through the `experimental-dapp-addresses-config` key.
-This key holds a Redis Set value.
-You must use commands such as SADD and SREM to manipulate the list of addresses.
-Addresses are encoded as hex strings without the leading `"0x"`.
-Redis values are case sensitive, so addresses must be in lowercase format.
-Example address value: `"0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a"`.
+This key holds a [Redis Set](https://redis.io/docs/latest/develop/data-types/sets/) value.
+You must use commands such as [`SADD`](https://redis.io/docs/latest/commands/sadd/) and [`SREM`]https://redis.io/docs/latest/commands/srem/() to manipulate the set of addresses.
 
-You may rewrite the list of addresses at any time,
+Application addresses must be encoded as hex strings.
+The prefix `0x` is ignored by the `authority-claimer` when loading applications adresses.
+However, it's advised to use it as a matter of convention.
+Example address value: `"0x0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a"`.
+
+> [!NOTE]
+> Duplicate addresses as well as malformed addresses are detected and logged.
+
+> [!TIP]
+> Application addresses are case insensitive even though Redis values are not.
+> So, even though,`"0x00000000000000000000000000000000deadbeef"` and `"0x00000000000000000000000000000000DeadBeef"` may be part of the same Redis Set, they are considered the same application address.
+
+You may update the contents of `experimental-dapp-addresses-config` at any time,
     the claimer will adjust accordingly.
-The list of addresses can be empty at any time,
+The set of addresses may be emptied at any time as well,
     the claimer will wait until an application address is added to the set to resume operations.
