+### Mining pools update
+
+By default, mining pools will be not automatically updated regularly (`config.MEMPOOL.AUTOMATIC_BLOCK_REINDEXING` is set to `false`). 
+
+To manually update your mining pools, you can use the `--update-pools` command line flag when you run the nodejs backend. For example `npm run start --update-pools`. This will trigger the mining pools update and automatically re-index appropriate blocks.
+
+You can enabled the automatic mining pools update by settings `config.MEMPOOL.AUTOMATIC_BLOCK_REINDEXING` to `true` in your `mempool-config.json`.
+
+When a `coinbase tag` or `coinbase address` change is detected, all blocks tagged to the `unknown` mining pools (starting from height 130635) will be deleted from the `blocks` table. Additionaly, all blocks which were tagged to the pool which has been updated will also be deleted from the `blocks` table. Of course, those blocks will be automatically reindexed.
+
 ### Re-index tables
 
 You can manually force the nodejs backend to drop all data from a specified set of tables for future re-index. This is mostly useful for the mining dashboard and the lightning explorer.
