+## Docker
+
+The TCK is also available as a Docker image, providing an easy way to run tests in an isolated environment.
+
+### Pull the Docker Image
+
+You can pull the pre-built Docker image from DockerHub:
+
+```bash
+docker pull ivaylogarnev/tck-client
+```
+
+### Running Tests
+
+The Docker image supports running tests against both local and testnet environments.
+
+#### Local Network (Default)
+To run tests against a local network:
+```bash
+# Run specific test
+docker run --network host -e TEST=AccountCreate ivaylogarnev/tck-client
+
+# Run all tests
+docker run --network host ivaylogarnev/tck-client
+```
+
+#### Testnet
+To run tests against Hedera Testnet:
+```bash
+docker run --network host \
+  -e NETWORK=testnet \
+  -e OPERATOR_ACCOUNT_ID=your-account-id \
+  -e OPERATOR_ACCOUNT_PRIVATE_KEY=your-private-key \
+  # Run specific test
+  -e TEST=AccountCreate \
+  ivaylogarnev/tck-client
+```
+
+### Available Tests
+Some of the available test options include:
+- AccountCreate
+- AccountUpdate
+- AccountDelete
+- AccountAllowanceDelete
+- AccountAllowanceApprove
+- TokenCreate
+- TokenUpdate
+- TokenDelete
+- TokenBurn
+- TokenMint
+- TokenAssociate
+- TokenDissociate
+- TokenFeeScheduleUpdate
+- TokenGrantKyc
+- TokenRevokeKyc
+- TokenPause
+- TokenUnpause
+- TokenFreeze
+- TokenUnfreeze
+- ALL (runs all tests)
+
+Running an invalid test name will display the complete list of available tests.
+
+### Building the Docker Image Locally
+
+If you want to build the image locally:
+```bash
+docker build -t tck-client .
+```
+
+Then run it using the same commands as above, replacing `ivaylogarnev/tck-client` with `tck-client`.
