 Mempool is the fully-featured mempool visualizer, explorer, and API service running at [mempool.space](https://mempool.space/). 
 
 It is an open-source project developed and operated for the benefit of the Bitcoin community, with a focus on the emerging transaction fee market that is evolving Bitcoin into a multi-layer ecosystem.

-### 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.
-
-Use the `--reindex` command to specify a list of comma separated table which will be truncated at start. Note that a 5 seconds delay will be observed before truncating tables in order to give you a chance to cancel (CTRL+C) in case of misuse of the command.
-
-Usage:
-```
-npm run start --reindex=blocks,hashrates
-```
-Example output:
-```
-Feb 13 14:55:27 [63246] WARN: <lightning> Indexed data for "hashrates" tables will be erased in 5 seconds (using '--reindex')
-Feb 13 14:55:32 [63246] NOTICE: <lightning> Table hashrates has been truncated
-```
