+
+# Add Operators
+
+> **Warning:** This is an alpha feature and is not yet recommended for production use.
+
+Expand a Charon cluster by adding new operators. This is a coordinated operation involving both existing and new operators.
+
+## Prerequisites
+
+Read `scripts/edit/add-operators/README.md` for full details if needed.
+
+Common prerequisites:
+1. `.env` file exists with `NETWORK` and `VC` variables set
+2. `.charon` directory with `cluster-lock.json` and `charon-enr-private-key`
+3. Docker is running
+4. `jq` installed
+
+## Role Selection
+
+Ask the user: **"Are you an existing operator in the cluster, or a new operator joining?"**
+
+### If Existing Operator
+
+**Script**: `scripts/edit/add-operators/existing-operator.sh`
+
+**Additional prerequisites**:
+- `.charon/cluster-lock.json` and `.charon/validator_keys/` must exist
+- The script will automatically stop the VC container for ASDB export
+
+**Arguments to gather**:
+- `--new-operator-enrs`: Comma-separated ENRs of the new operators joining
+- Whether to use `--dry-run` first
+
+**Run**:
+```bash
+./scripts/edit/add-operators/existing-operator.sh \
+    --new-operator-enrs "enr:-...,enr:-..." \
+    [--dry-run]
+```
+
+Set `WORK_DIR` env var to override the repository root directory if running from a custom location.
+
+
+The script will export the anti-slashing database, run the P2P ceremony, update keys, and print commands to start containers manually. After completion, remind the user to **wait ~2 epochs before starting** containers.
+
+### If New Operator
+
+**Script**: `scripts/edit/add-operators/new-operator.sh`
+
+This is a **two-step process**:
+
+#### Step 1: Generate ENR
+
+Ask if the user needs to generate an ENR (first time setup):
+
+```bash
+./scripts/edit/add-operators/new-operator.sh --generate-enr
+```
+
+This creates `.charon/charon-enr-private-key` and displays the ENR. Tell the user to **share this ENR with the existing operators**.
+The existing operators, in turn, need to share the `cluster-lock.json` with the new operators, which contains the current cluster configuration and is required for the P2P ceremony.
+
+#### Step 2: Join the Ceremony
+
+After the existing operators have the ENR, gather:
+- `--new-operator-enrs`: Comma-separated ENRs of ALL new operators (including their own)
+- `--cluster-lock`: Path to the `cluster-lock.json` received from existing operators
+- Whether to use `--dry-run` first
+
+```bash
+./scripts/edit/add-operators/new-operator.sh \
+    --new-operator-enrs "enr:-...,enr:-..." \
+    --cluster-lock ./received-cluster-lock.json \
+    [--dry-run]
+```
+
+Set `WORK_DIR` env var to override the repository root directory if running from a custom location.
+
+Remind the user that **all operators (existing AND new) must participate simultaneously** in the P2P ceremony. After completion, the script will print commands to start containers manually. The new operator does NOT have slashing protection history (fresh start).

+# Add Validators
+
+> **Warning:** This is an alpha feature and is not yet recommended for production use.
+
+Add new validators to an existing Charon distributed validator cluster. All operators must run this simultaneously as it requires a P2P ceremony.
+
+## Prerequisites
+
+Before running, verify:
+1. `.env` file exists with `NETWORK` and `VC` variables set
+2. `.charon/cluster-lock.json` and `.charon/deposit-data*.json` exist
+3. Docker is running
+4. `jq` is installed
+
+Read `scripts/edit/add-validators/README.md` for full details if needed.
+
+## Gather Arguments
+
+Ask the user for the following required arguments using AskUserQuestion:
+
+1. **Number of validators** (`--num-validators`): How many new validators to add (positive integer)
+2. **Withdrawal addresses** (`--withdrawal-addresses`): Comma-separated Ethereum withdrawal address(es)
+3. **Fee recipient addresses** (`--fee-recipient-addresses`): Comma-separated fee recipient address(es)
+
+Also ask whether they want to:
+- Run with `--dry-run` first to preview the operation
+- Use `--unverified` flag (skip key verification, used for remote KeyManager API setups)
+
+## Execution
+
+Run the script from the repository root:
+
+```bash
+./scripts/edit/add-validators/add-validators.sh \
+    --num-validators <N> \
+    --withdrawal-addresses <addrs> \
+    --fee-recipient-addresses <addrs> \
+    [--unverified] [--dry-run]
+```
+
+Set `WORK_DIR` env var to override the repository root directory if running from a custom location.
+
+The script will:
+1. Validate prerequisites
+2. Display current cluster info (operators, validators)
+3. Run a P2P ceremony (all operators must participate simultaneously)
+4. Stop containers if they were running
+5. Backup `.charon/` to `./backups/`
+6. Install new configuration
+7. Print commands to start containers manually
+
+Remind the user that **all operators must run this script at the same time** for the P2P ceremony to succeed.

+
+Refresh private key shares held by operators while keeping the same validator public keys. Validators stay registered on the beacon chain - only the operator key shares change. All operators must participate simultaneously.
+
+## Use Cases
+
+- Security concerns: private key shares may have been compromised
+- Key rotation: regular security practice
+- Recovery: after a security incident
+
+## Prerequisites
+
+Before running, verify:

+# Remove Operators
+
+> **Warning:** This is an alpha feature and is not yet recommended for production use.
+
+Remove one or more operators from a Charon cluster. Whether removed operators need to participate depends on fault tolerance.
+
+## Prerequisites
+
+Read `scripts/edit/remove-operators/README.md` for full details if needed.
+
+Common prerequisites:
+1. `.env` file exists with `NETWORK` and `VC` variables set
+2. `.charon` directory with `cluster-lock.json` and `validator_keys`
+3. Docker is running
+4. `jq` installed
+
+## Fault Tolerance Context
+
+Explain to the user:
+- Fault tolerance `f = operators - threshold`
+- If removing **<= f** operators: removed operators do NOT need to participate (they just stop their nodes)
+- If removing **> f** operators: removed operators MUST also participate using `removed-operator.sh`
+
+## Role Selection
+
+Ask the user: **"Are you a remaining operator (staying in the cluster) or a removed operator (leaving the cluster)?"**
+
+### If Remaining Operator
+
+**Script**: `scripts/edit/remove-operators/remaining-operator.sh`
+
+**Additional prerequisites**:
+- `.charon/validator_keys/` must exist
+- The script will automatically stop the VC container for ASDB export
+
+**Arguments to gather**:
+- `--operator-enrs-to-remove`: Comma-separated ENRs of operators being removed
+- `--participating-operator-enrs` (only if removal exceeds fault tolerance): Comma-separated ENRs of ALL participating operators
+- `--new-threshold` (optional): Override the default threshold (defaults to ceil(n * 2/3))
+- Whether to use `--dry-run` first
+
+**Run**:
+```bash
+./scripts/edit/remove-operators/remaining-operator.sh \
+    --operator-enrs-to-remove "enr:-...,enr:-..." \
+    [--participating-operator-enrs "enr:-...,enr:-..."] \
+    [--new-threshold N] \
+    [--dry-run]
+```
+
+Set `WORK_DIR` env var to override the repository root directory if running from a custom location.
+
+After completion, the script will print commands to start containers manually. Remind the user to **wait ~2 epochs before starting** containers.
+
+### If Removed Operator
+
+**Script**: `scripts/edit/remove-operators/removed-operator.sh`
+
+This is **only needed when the removal exceeds fault tolerance**. If within fault tolerance, the removed operator simply stops their node.
+
+**Additional prerequisites**:
+- `.charon/charon-enr-private-key` must exist
+- `.charon/validator_keys/` must exist
+
+**Arguments to gather**:
+- `--operator-enrs-to-remove`: Comma-separated ENRs of operators being removed
+- `--participating-operator-enrs`: Comma-separated ENRs of ALL participating operators (must include your own ENR)
+- `--new-threshold` (optional): Override the default threshold
+- Whether to use `--dry-run` first
+
+**Run**:
+```bash
+./scripts/edit/remove-operators/removed-operator.sh \
+    --operator-enrs-to-remove "enr:-...,enr:-..." \
+    --participating-operator-enrs "enr:-...,enr:-..." \
+    [--new-threshold N] \
+    [--dry-run]
+```
+
+Set `WORK_DIR` env var to override the repository root directory if running from a custom location.
+
+The script will participate in the ceremony and then stop your charon and VC containers. No ASDB operations are needed since you're leaving the cluster.
