+# How to reset the state of your chain
+
+This guide will walk you through how you reset the state of your chain.
+
+:::warning Disclaimer
+By definition, reseting the state is deleting your chain's data. Make sure you understand the implications of this prior to completion this guide.
+:::
+
+Some reason you might need to reset the state of your chain are:
+* During testing and development
+* During upgrades with breaking changes
+* Hardforks
+
+## Prerequisities 
+
+In order to complete this guide, you will need to have completed either the [quick start tutorial](/tutorials/quick-start.md) or the [build our chain tutorial](/tutorials/wordle.md).
+
+## Quick Start
+
+When you run your chain with `rollkit start` you will create a `.rollkit` directory in your root directory. 
+
+This directory will look like the following. 
+
+```bash
+tree $HOME/.rollkit
+
+├── config
+│   ├── config.toml
+│   ├── genesis.json
+│   ├── node_key.json
+│   └── priv_validator_key.json
+└── data
+    ├── priv_validator_state.json
+    └── rollkit
+        ├── 000001.sst
+        ├── 000001.vlog
+        ├── 000002.sst
+        ├── 000002.vlog
+        ├── DISCARD
+        ├── KEYREGISTRY
+        └── MANIFEST
+```
+
+To reset the state of the chain, delete the entire `.rollkit` directory.
+
+```bash
+rm -rf $HOME/.rollkit
+```
+
+When you launch your chain again with `rollkit start` your `.rollkit` directory will be re-created and you will see your chain starting at block height 1 again.
+
+## Wordle
+
+When you ran your wordle chain in the [build your chain turtorial](/tutorials/wordle.md), it created a `.wordle` directory.
+
+This directory will look like the following:
+
+```bash
+tree $HOME/.wordle
+
+├── config
+│   ├── app.toml
+│   ├── client.toml
+│   ├── config.toml
+│   ├── genesis.json
+│   ├── gentx
+│   │   └── gentx-6e46bd1f53acead98b43e63fcf2bd5435499350d.json
+│   ├── node_key.json
+│   └── priv_validator_key.json
+├── data
+│   ├── application.db
+│   │   ├── 000001.log
+│   │   ├── CURRENT
+│   │   ├── LOCK
+│   │   ├── LOG
+│   │   └── MANIFEST-000000
+│   ├── priv_validator_state.json
+│   ├── rollkit
+│   │   ├── 000001.sst
+│   │   ├── 000001.vlog
+│   │   ├── DISCARD
+│   │   ├── KEYREGISTRY
+│   │   └── MANIFEST
+│   └── snapshots
+│       └── metadata.db
+│           ├── 000001.log
+│           ├── CURRENT
+│           ├── LOCK
+│           ├── LOG
+│           └── MANIFEST-000000
+└── keyring-test
+    ├── 4a90e750914792c2d7f98775c13a588d9d304bd0.address
+    ├── 53dab037ac3bd380f4a9192b2c6eedbe95fce180.address
+    ├── alice.info
+    └── bob.info
+```
+
+The directories you need to delete to reset your state are in the `.wordle/data` directory.
+
+```bash
+$HOME/.wordle/data/application.db
+$HOME/.wordle/data/rollkit
+$HOME/.wordle/data/snapshots 
+```
+
+You can delete them with the following command:
+
+```bash
+rollkit tendermint unsafe-reset-all
+```
+
+When you launch your chain again with your `rollkit start <flags>` command, these data directories will be re-created and you will see your chain starting at block height 1 again.
