+- [**exchanges.yaml**](https://github.com/catchain/address-book/blob/master/source/exchanges.yaml) is for exchanges and DEXes.
+- [**system.yaml**](https://github.com/catchain/address-book/blob/master/source/system.yaml) is for core blockchain contracts like root DNS, pow-givers, elector etc.

 Entry structure must be as follows:
 
 ```yaml
-# new line
 - address: TON address in any format
-  tonIcon: Special field, please don't fill it out
   name: Short name for your project, 3-32 symbols
   description: |-
-    Please provide short description for your project.
+    You may provide short description for your project.
     Any amount of text and links are allowed.
-  type: Contract type (see below)
-# new line
+  type: wallet (or empty: see below)
 ```
 
-### Contract type
-`type` field can either be empty (just don't use it in entry) or one of these values: `wallet`, `nft_collection`, `jetton`, `pool`. Use `wallet` type for _all_ wallets (including validator addresses) and uninit addresses.
+#### Contract type
+`type` field can either be empty (just don't use it in entry) or one of these values: `wallet`, `nft_collection`, `jetton`, `pool`.
+
+**⚠️ Important:** use `wallet` type for **all wallets** (including validator addresses) and **uninit** addresses.
+
+This field is needed because some addresses in TON have to be in other format (UQ vs EQ). The address itself can be in any format, just set the correct `type`.
