 ## Project structure
 
@@ -129,22 +129,51 @@ The architecture of this project is following:
 
 1. fast generate event handlers 
 
-```
+```bash
 pbpaste | cut -d '=' -f 1 | tr -d ' '  | xargs -I_ echo "processor.addEventHandler(Event._, dummy);"
 ```
 
 2. enable debug logs (in .env)
 
-```
+```bash
 SQD_DEBUG=squid:log
 ```
 
 3. generate metagetters from getters 
 
-```
+```bash
 pbpaste | grep 'export'  | xargs -I_ echo "_  return proc.  }"
 ```
 
+4. Enable different chain (currently only Kusama and Polkadot are supported)
+
+> [!NOTE]
+> By default the chain is set to `kusama`
+
+```bash
+CHAIN=polkadot # or kusama
+```
+
+5. enable offers 
+
+`Offers` support is a hack on top of the `Atomic Swap` to enable `Offers` set in `.env` file
+
+```bash
+OFFER=<ID_OF_THE_COLLECTION>
+```
+
+### Note on Swaps
+
+1. Swaps can be overwritten at any time
+
+Therefore if you have a swap, and will create a new one, the old one will be overwritten. This is mentioned in `createSwap.ts` Line 31.
+
+2. Swaps are autocancelled by few conditions
+
+- if you `burn` the NFT
+- if you `transfer` the NFT
+
+in any other condition the swap will have to be cancelled manually.
