-## Configuration
-
-We have plenty of [docker-compose files](documentation/compose/DOCKER_COMPOSE.md) as examples. They're built for various configuration stacks.
-
-# Guides
-
-- [SSO configuration](documentation/guides/SSO.md)
-- [AWS IAM configuration](documentation/guides/AWS_IAM.md)
-- [Docker-compose files](documentation/compose/DOCKER_COMPOSE.md)
-- [Connection to a secure broker](documentation/guides/SECURE_BROKER.md)
-- [Configure seriliazation/deserialization plugins or code your own](documentation/guides/Serialization.md)
+To run UI for Apache Kafka, you can use either a pre-built Docker image or build it (or a jar file) yourself.
 
-### Configuration File
-Example of how to configure clusters in the [application-local.yml](https://github.com/provectus/kafka-ui/blob/master/kafka-ui-api/src/main/resources/application-local.yml) configuration file:
+## Quick start (Demo run)
 
-
-```sh
-kafka:
-  clusters:
-    -
-      name: local
-      bootstrapServers: localhost:29091
-      schemaRegistry: http://localhost:8085
-      schemaRegistryAuth:
-        username: username
-        password: password
-#     schemaNameTemplate: "%s-value"
-      metrics:
-        port: 9997
-        type: JMX
-    -
+```
+docker run -it -p 8080:8080 -e DYNAMIC_CONFIG_ENABLED=true provectuslabs/kafka-ui
 ```
 
-* `name`: cluster name
-* `bootstrapServers`: where to connect
-* `schemaRegistry`: schemaRegistry's address
-* `schemaRegistryAuth.username`: schemaRegistry's basic authentication username
-* `schemaRegistryAuth.password`: schemaRegistry's basic authentication password
-* `schemaNameTemplate`: how keys are saved to schemaRegistry
-* `metrics.port`: open JMX port of a broker
-* `metrics.type`: Type of metrics, either JMX or PROMETHEUS. Defaulted to JMX.
-* `readOnly`: enable read only mode
-
-Configure as many clusters as you need by adding their configs below separated with `-`.
-
-## Running a Docker Image
-The official Docker image for UI for Apache Kafka is hosted here: [hub.docker.com/r/provectuslabs/kafka-ui](https://hub.docker.com/r/provectuslabs/kafka-ui).

-# How to configure AWS IAM Authentication
-
-UI for Apache Kafka comes with built-in [aws-msk-iam-auth](https://github.com/aws/aws-msk-iam-auth) library.
-
-You could pass sasl configs in properties section for each cluster.
-
-More details could be found here: [aws-msk-iam-auth](https://github.com/aws/aws-msk-iam-auth)
- 
-## Examples: 
-
-Please replace 
-* <KAFKA_URL> with broker list
-* <PROFILE_NAME> with your aws profile
-
-
-### Running From Docker Image
-
-```sh
-docker run -p 8080:8080 \
-    -e KAFKA_CLUSTERS_0_NAME=local \
-    -e KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS=<KAFKA_URL> \

-# Topics data masking
-
-You can configure kafka-ui to mask sensitive data shown in Messages page.
-
-Several masking policies supported:
-
-### REMOVE
-For json objects - remove target fields, otherwise - return "null" string.
-```yaml
-- type: REMOVE
-  fields: [ "id", "name" ]
-  ...
-```
-
-Apply examples:
-```
-{ "id": 1234, "name": { "first": "James" }, "age": 30 } 
- ->
-{ "age": 30 } 
-```
-```
-non-json string -> null
-```
-
-### REPLACE
-For json objects - replace target field's values with specified replacement string (by default with `***DATA_MASKED***`). Note: if target field's value is object, then replacement applied to all its fields recursively (see example). 
-
-```yaml
-- type: REPLACE
-  fields: [ "id", "name" ]
-  replacement: "***"  #optional, "***DATA_MASKED***" by default
-  ...
-```
-
-Apply examples:
-```
-{ "id": 1234, "name": { "first": "James", "last": "Bond" }, "age": 30 } 
- ->
-{ "id": "***", "name": { "first": "***", "last": "***" }, "age": 30 } 
-```
-```
-non-json string -> ***
-```
-
-### MASK
-Mask target field's values with specified masking characters, recursively (spaces and line separators will be kept as-is).
-`pattern` array specifies what symbols will be used to replace upper-case chars, lower-case chars, digits and other symbols correspondingly.
-
-```yaml
-- type: MASK
-  fields: [ "id", "name" ]
-  pattern: ["A", "a", "N", "_"]   # optional, default is ["X", "x", "n", "-"]
-  ...
-```
-
-Apply examples:
-```
-{ "id": 1234, "name": { "first": "James", "last": "Bond!" }, "age": 30 } 
- ->
-{ "id": "NNNN", "name": { "first": "Aaaaa", "last": "Aaaa_" }, "age": 30 } 
-```
-```
-Some string! -> Aaaa aaaaaa_
-```
-
-----
-
-For each policy, if `fields` not specified, then policy will be applied to all object's fields or whole string if it is not a json-object.
-
-You can specify which masks will be applied to topic's keys/values. Multiple policies will be applied if topic matches both policy's patterns.
-
-Yaml configuration example:
-```yaml
-kafka:
-  clusters:
-    - name: ClusterName
-      # Other Cluster configuration omitted ... 
-      masking:
-        - type: REMOVE

-# Kafkaui Protobuf Support
-
-### This document is deprecated, please see examples in [Serialization document](Serialization.md).
-
-Kafkaui supports deserializing protobuf messages in two ways:
-1. Using Confluent Schema Registry's [protobuf support](https://docs.confluent.io/platform/current/schema-registry/serdes-develop/serdes-protobuf.html).
-2. Supplying a protobuf file as well as a configuration that maps topic names to protobuf types.
-
-## Configuring Kafkaui with a Protobuf File
-
-To configure Kafkaui to deserialize protobuf messages using a supplied protobuf schema add the following to the config:
-```yaml
-kafka:
-  clusters:
-    - # Cluster configuration omitted...
-      # protobufFilesDir specifies root location for proto files (will be scanned recursively)
-      # NOTE: if 'protobufFilesDir' specified, then 'protobufFile' and 'protobufFiles' settings will be ignored
-      protobufFilesDir: "/path/to/my-protobufs"
-      # (DEPRECATED) protobufFile is the path to the protobuf schema. (deprecated: please use "protobufFiles")
-      protobufFile: path/to/my.proto
-      # (DEPRECATED) protobufFiles is the location of one or more protobuf schemas
-      protobufFiles:
-        - /path/to/my-protobufs/my.proto

-        - /path/to/my-protobufs:test/test.proto

-      # the message's value if the topic is not found in protobufMessageNameByTopic.    
-      protobufMessageName: my.DefaultValType
-      # protobufMessageNameByTopic is a mapping of topic names to protobuf types.
-      # This mapping is required and is used to deserialize the Kafka message's value.
-      protobufMessageNameByTopic:
-        topic1: my.Type1
-        topic2: my.Type2
-      # protobufMessageNameForKey is the default protobuf type that is used to deserialize
-      # the message's key if the topic is not found in protobufMessageNameForKeyByTopic.
-      protobufMessageNameForKey: my.DefaultKeyType
-      # protobufMessageNameForKeyByTopic is a mapping of topic names to protobuf types.
-      # This mapping is optional and is used to deserialize the Kafka message's key.
-      # If a protobuf type is not found for a topic's key, the key is deserialized as a string,
-      # unless protobufMessageNameForKey is specified.
-      protobufMessageNameForKeyByTopic:
-        topic1: my.KeyType1
-```
-
-Same config with flattened config (for docker-compose):

-# How to configure SSO
-SSO require additionaly to configure TLS for application, in that example we will use self-signed certificate, in case of use legal certificates please skip step 1.
-## Step 1
-At this step we will generate self-signed PKCS12 keypair.
-``` bash
-mkdir cert
-keytool -genkeypair -alias ui-for-apache-kafka -keyalg RSA -keysize 2048 \
-  -storetype PKCS12 -keystore cert/ui-for-apache-kafka.p12 -validity 3650
-```
-## Step 2
-Create new application in any SSO provider, we will continue with [Auth0](https://auth0.com).
-
-<img src="https://github.com/provectus/kafka-ui/raw/images/images/sso-new-app.png" width="70%"/>
-
-After that need to provide callback URLs, in our case we will use `https://127.0.0.1:8080/login/oauth2/code/auth0`
-
-<img src="https://github.com/provectus/kafka-ui/raw/images/images/sso-configuration.png" width="70%"/>
-
-This is a main parameters required for enabling SSO
-
-<img src="https://github.com/provectus/kafka-ui/raw/images/images/sso-parameters.png" width="70%"/>
-
-## Step 3
-To launch UI for Apache Kafka with enabled TLS and SSO run following:
-``` bash
-docker run -p 8080:8080 -v `pwd`/cert:/opt/cert -e AUTH_TYPE=LOGIN_FORM \
-  -e SECURITY_BASIC_ENABLED=true \
-  -e SERVER_SSL_KEY_STORE_TYPE=PKCS12 \
-  -e SERVER_SSL_KEY_STORE=/opt/cert/ui-for-apache-kafka.p12 \
-  -e SERVER_SSL_KEY_STORE_PASSWORD=123456 \
-  -e SERVER_SSL_KEY_ALIAS=ui-for-apache-kafka \
-  -e SERVER_SSL_ENABLED=true \
-  -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_CLIENTID=uhvaPKIHU4ZF8Ne4B6PGvF0hWW6OcUSB \

-  -e TRUST_STORE=/opt/cert/ui-for-apache-kafka.p12 \
-  -e TRUST_STORE_PASSWORD=123456 \
-provectuslabs/kafka-ui:latest
-```
-In the case with trusted CA-signed SSL certificate and SSL termination somewhere outside of application we can pass only SSO related environment variables:
-``` bash
-docker run -p 8080:8080 -v `pwd`/cert:/opt/cert -e AUTH_TYPE=OAUTH2 \
-  -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_CLIENTID=uhvaPKIHU4ZF8Ne4B6PGvF0hWW6OcUSB \

-  -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_SCOPE=openid \
-provectuslabs/kafka-ui:latest
-```
-
-## Step 4 (Load Balancer HTTP) (optional)
-If you're using load balancer/proxy and use HTTP between the proxy and the app, you might want to set `server_forward-headers-strategy` to `native` as well (`SERVER_FORWARDHEADERSSTRATEGY=native`), for more info refer to [this issue](https://github.com/provectus/kafka-ui/issues/1017).
-
-## Step 5 (Azure) (optional)
-For Azure AD (Office365) OAUTH2 you'll want to add additional environment variables:
-
-```bash
-docker run -p 8080:8080 \
-        -e KAFKA_CLUSTERS_0_NAME="${cluster_name}"\
-        -e KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS="${kafka_listeners}" \
-        -e KAFKA_CLUSTERS_0_KAFKACONNECT_0_ADDRESS="${kafka_connect_servers}"
-        -e AUTH_TYPE=OAUTH2 \
-        -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_CLIENTID=uhvaPKIHU4ZF8Ne4B6PGvF0hWW6OcUSB \
-        -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_CLIENTSECRET=YXfRjmodifiedTujnkVr7zuW9ECCAK4TcnCio-i \
-        -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_SCOPE="https://graph.microsoft.com/User.Read" \

-        -d provectuslabs/kafka-ui:latest"
-```
-
-Note that scope is created by default when Application registration is done in Azure portal.
-You'll need to update application registration manifest to include `"accessTokenAcceptedVersion": 2`

documentation/guides/Serialization.md

-## Serialization and deserialization and custom plugins
-
-Kafka-ui supports multiple ways to serialize/deserialize data.
-
-
-### Int32, Int64, UInt32, UInt64
-Big-endian 4/8 bytes representation of signed/unsigned integers.
-
-### Base64
-Base64 (RFC4648) binary data representation. Can be useful in case if the actual data is not important, but exactly the same (byte-wise) key/value should be send.
-
-### String 
-Treats binary data as a string in specified encoding. Default encoding is UTF-8.
-
-Class name: `com.provectus.kafka.ui.serdes.builtin.StringSerde`
-
-Sample configuration (if you want to overwrite default configuration):
-```yaml
-kafka:
-  clusters:
-    - name: Cluster1
-      # Other Cluster configuration omitted ... 
-      serde:
-          # registering String serde with custom config
-        - name: AsciiString
-          className: com.provectus.kafka.ui.serdes.builtin.StringSerde
-          properties:
-            encoding: "ASCII"
-        
-          # overriding build-it String serde config   
-        - name: String 
-          properties:
-            encoding: "UTF-16"
-```
-
-### Protobuf
-
-Class name: `com.provectus.kafka.ui.serdes.builtin.ProtobufFileSerde`
-
-Sample configuration:
-```yaml
-kafka:
-  clusters:
-    - name: Cluster1
-      # Other Cluster configuration omitted ... 
-      serde:
-        - name: ProtobufFile
-          properties:
-            # path to the protobuf schema files directory
-            protobufFilesDir: "path/to/protofiles"
-            # default protobuf type that is used for KEY serialization/deserialization
-            # optional
-            protobufMessageNameForKey: my.Type1
-            # mapping of topic names to protobuf types, that will be used for KEYS  serialization/deserialization
-            # optional
-            protobufMessageNameForKeyByTopic:
-              topic1: my.KeyType1
-              topic2: my.KeyType2
-            # default protobuf type that is used for VALUE serialization/deserialization
-            # optional, if not set - first type in file will be used as default
-            protobufMessageName: my.Type1
-            # mapping of topic names to protobuf types, that will be used for VALUES  serialization/deserialization
-            # optional
-            protobufMessageNameByTopic:
-              topic1: my.Type1
-              "topic.2": my.Type2
-```
-Docker-compose sample for Protobuf serialization is [here](../compose/kafka-ui-serdes.yaml).
-
-Legacy configuration for protobuf is [here](Protobuf.md).
-
-### SchemaRegistry
-SchemaRegistry serde is automatically configured if schema registry properties set on cluster level.
-But you can add new SchemaRegistry-typed serdes that will connect to another schema-registry instance. 
-
-Class name: `com.provectus.kafka.ui.serdes.builtin.sr.SchemaRegistrySerde`
-
-Sample configuration:
-```yaml
-kafka:
-  clusters:
-    - name: Cluster1
-      # this url will be used by "SchemaRegistry" by default
-      schemaRegistry: http://main-schema-registry:8081
-      serde:
-        - name: AnotherSchemaRegistry
-          className: com.provectus.kafka.ui.serdes.builtin.sr.SchemaRegistrySerde
-          properties:
-            url:  http://another-schema-registry:8081
-            # auth properties, optional
-            username: nameForAuth
-            password: P@ssW0RdForAuth
-        
-          # and also add another SchemaRegistry serde
-        - name: ThirdSchemaRegistry
-          className: com.provectus.kafka.ui.serdes.builtin.sr.SchemaRegistrySerde
-          properties:
-            url:  http://another-yet-schema-registry:8081
-```
-
-## Setting serdes for specific topics
-You can specify preferable serde for topics key/value. This serde will be chosen by default in UI on topic's view/produce pages. 
-To do so, set `topicValuesPattern/topicValuesPattern` properties for the selected serde. Kafka-ui will choose a first serde that matches specified pattern.
-
-Sample configuration:
-```yaml
-kafka:
-  clusters:
-    - name: Cluster1
-      serde:
-        - name: String
-          topicKeysPattern: click-events|imp-events
-        
-        - name: Int64
-          topicKeysPattern: ".*-events"
-        
-        - name: SchemaRegistry
-          topicValuesPattern: click-events|imp-events
-```
-
-
-## Default serdes
-You can specify which serde will be chosen in UI by default if no other serdes selected via `topicKeysPattern/topicValuesPattern` settings.
-
-Sample configuration:
-```yaml
-kafka:
-  clusters:
-    - name: Cluster1
-      defaultKeySerde: Int32
-      defaultValueSerde: String
-      serde:
-        - name: Int32
-          topicKeysPattern: click-events|imp-events
-```
-
-## Fallback
-If selected serde couldn't be applied (exception was thrown), then fallback (String serde with UTF-8 encoding) serde will be applied. Such messages will be specially highlighted in UI.
-
-## Custom pluggable serde registration
-You can implement your own serde and register it in kafka-ui application.
-To do so:
-1. Add `kafka-ui-serde-api` dependency (should be downloadable via maven central)
-2. Implement `com.provectus.kafka.ui.serde.api.Serde` interface. See javadoc for implementation requirements.
-3. Pack your serde into uber jar, or provide directory with no-dependency jar and it's dependencies jars
-
-
-Example pluggable serdes :
-https://github.com/provectus/kafkaui-smile-serde
-https://github.com/provectus/kafkaui-glue-sr-serde
-
-Sample configuration:
-```yaml
-kafka:
-  clusters:
-    - name: Cluster1
-      serde:
-        - name: MyCustomSerde
-          className: my.lovely.org.KafkaUiSerde
-          filePath: /var/lib/kui-serde/my-kui-serde.jar
-          
-        - name: MyCustomSerde2
-          className: my.lovely.org.KafkaUiSerde2
-          filePath: /var/lib/kui-serde2
-          properties:
-            prop1: v1

-Kafka-UI Project Roadmap
-====================
-
-Roadmap exists in a form of a github project board and is located [here](https://github.com/provectus/kafka-ui/projects/8).
-
-### How to use this document
-
-The roadmap provides a list of features we decided to prioritize in project development. It should serve as a reference point to understand projects' goals.
-
-We do prioritize them based on the feedback from the community, our own vision and other conditions and circumstances. 
-
-The roadmap sets the general way of development. The roadmap is mostly about long-term features. All the features could be re-prioritized, rescheduled or canceled.
-
-If there's no feature `X`, that **doesn't** mean we're **not** going to implement it. Feel free to raise the issue for the consideration. <br/>
-If a feature you want to see live is not present on roadmap, but there's an issue for the feature, feel free to vote for it using reactions in the issue.
-
-
-### How to contribute
-
-Since the roadmap consists mostly of big long-term features, implementing them might be not easy for a beginner outside collaborator.
-
-A good starting point is checking the [CONTRIBUTING.md](https://github.com/provectus/kafka-ui/blob/master/CONTRIBUTING.md) document.

-# Build & Run
-
-Once you installed the prerequisites and cloned the repository, run the following steps in your project directory:
-
-## Step 1 : Build
-> **_NOTE:_**  If you are an macOS M1 User then please keep in mind below things
-
-> Make sure you have ARM supported java installed
-
-> Skip the maven tests as they might not be successful
-
-- Build a docker image with the app
-```sh
-./mvnw clean install -Pprod
-```
-- if you need to build the frontend `kafka-ui-react-app`, go here
-     - [kafka-ui-react-app-build-documentation](../../../kafka-ui-react-app/README.md)
-
-<a name="cmd_to_build_kafkaui_without_docker"></a>
-- In case you want to build `kafka-ui-api` by skipping the tests
-```sh
-./mvnw clean install -Dmaven.test.skip=true -Pprod
-```
-
-- To build only the `kafka-ui-api` you can use this command:
-```sh
-./mvnw -f kafka-ui-api/pom.xml clean install -Pprod -DskipUIBuild=true
-```
-
-If this step is successful, it should create a docker image named `provectuslabs/kafka-ui` with `latest` tag on your local machine except macOS M1.
-
-## Step 2 : Run
-#### Using Docker Compose
-> **_NOTE:_**  If you are an macOS M1 User then you can use arm64 supported docker compose script `./documentation/compose/kafka-ui-arm64.yaml`
- - Start the `kafka-ui` app using docker image built in step 1 along with Kafka clusters:
-```sh
-docker-compose -f ./documentation/compose/kafka-ui.yaml up -d
-```
-
-#### Using Spring Boot Run
- - If you want to start only kafka clusters (to run the `kafka-ui` app via `spring-boot:run`):
-```sh
-docker-compose -f ./documentation/compose/kafka-clusters-only.yaml up -d
-```
-- Then start the app.
-```sh
-./mvnw spring-boot:run -Pprod
-
-# or
-
-./mvnw spring-boot:run -Pprod -Dspring.config.location=file:///path/to/conf.yaml
-```
-
-#### Running in kubernetes
-- Using Helm Charts
-```sh bash
-helm repo add kafka-ui https://provectus.github.io/kafka-ui
-helm install kafka-ui kafka-ui/kafka-ui
-```
-To read more please follow to [chart documentation](../../../charts/kafka-ui/README.md).
-
-## Step 3 : Access Kafka-UI
