+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to make participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+- Using welcoming and inclusive language
+- Being respectful of differing viewpoints and experiences
+- Gracefully accepting constructive criticism
+- Focusing on what is best for the community
+- Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+- The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+- Trolling, insulting/derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at <enteremailhere>. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

 ## Quick Start with Single Binary ##
-* Download the latest binary from https://github.com/seaweedfs/seaweedfs/releases and unzip a single binary file `weed` or `weed.exe`
+* Download the latest binary from https://github.com/seaweedfs/seaweedfs/releases and unzip a single binary file `weed` or `weed.exe`. Or run `go install github.com/seaweedfs/seaweedfs/weed@latest`.
 * Run `weed server -dir=/some/data/dir -s3` to start one master, one volume server, one filer, and one S3 gateway.

 Also, to increase capacity, just add more volume servers by running `weed volume -dir="/some/data/dir2" -mserver="<master_host>:9333" -port=8081` locally, or on a different machine, or on thousands of machines. That is it!

+# SEAWEEDFS - helm chart (2.x+)
+
+## Getting Started
+
+### Add the helm repo
+
+`helm repo add seaweedfs https://seaweedfs.github.io/seaweedfs/helm`
+
+### Install the helm chart
+
+`helm install seaweedfs seaweedfs/seaweedfs`
+
+### (Recommended) Provide `values.yaml`
+
+`helm install --values=values.yaml seaweedfs seaweedfs/seaweedfs`
+
+## Info:
+* master/filer/volume are stateful sets with anti-affinity on the hostname,
+so your deployment will be spread/HA.
+* chart is using memsql(mysql) as the filer backend to enable HA (multiple filer instances) and backup/HA memsql can provide.
+* mysql user/password are created in a k8s secret (secret-seaweedfs-db.yaml) and injected to the filer with ENV.
+* cert config exists and can be enabled, but not been tested, requires cert-manager to be installed.
+
+## Prerequisites
+### Database
+
+leveldb is the default database this only supports one filer replica.
+
+To have multiple filers a external datastore is recommened.
+
+Such as MySQL-compatible database, as specified in the `values.yaml` at `filer.extraEnvironmentVars`. 
+This database should be pre-configured and initialized by running:
+```sql
+CREATE TABLE IF NOT EXISTS `filemeta` (
+  `dirhash`   BIGINT NOT NULL       COMMENT 'first 64 bits of MD5 hash value of directory field',
+  `name`      VARCHAR(766) NOT NULL COMMENT 'directory or file name',
+  `directory` TEXT NOT NULL         COMMENT 'full path to parent directory',
+  `meta`      LONGBLOB,
+  PRIMARY KEY (`dirhash`, `name`)
+) DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin;
+```
+
+Alternative database can also be configured (e.g. leveldb, postgres) following the instructions at `filer.extraEnvironmentVars`.
+
+### Node Labels
+Kubernetes nodes can have labels which help to define which node(Host) will run which pod:
+
+Here is an example:
+* s3/filer/master needs the label **sw-backend=true**
+* volume need the label **sw-volume=true**
+
+to label a node to be able to run all pod types in k8s:
+```
+kubectl label node YOUR_NODE_NAME sw-volume=true,sw-backend=true
+```
+
+on production k8s deployment you will want each pod to have a different host,
+especially the volume server and the masters, all pods (master/volume/filer)
+should have anti-affinity rules to disallow running multiple component pods  on the same host.
+
+If you still want to run multiple pods of the same component (master/volume/filer) on the same host please set/update the corresponding affinity rule in values.yaml to an empty one:
+
+```affinity: ""```
+
+## PVC - storage class ###
+
+On the volume stateful set added support for k8s PVC, currently example
+with the simple local-path-provisioner from Rancher (comes included with k3d / k3s)
+https://github.com/rancher/local-path-provisioner
+
+you can use ANY storage class you like, just update the correct storage-class
+for your deployment.
+
+## current instances config (AIO):
+
+1 instance for each type (master/filer+s3/volume)
+
+You can update the replicas count for each node type in values.yaml,
+need to add more nodes with the corresponding labels if applicable.
+
+Most of the configuration are available through values.yaml any pull requests to expand functionality or usability are greatly appreciated. Any pull request must pass [chart-testing](https://github.com/helm/chart-testing).

-# SEAWEEDFS - helm chart (2.x)
-
-## Info:
-* master/filer/volume are stateful sets with anti-affinity on the hostname,
-so your deployment will be spread/HA.
-* chart is using memsql(mysql) as the filer backend to enable HA (multiple filer instances)
-and backup/HA memsql can provide.
-* mysql user/password are created in a k8s secret (secret-seaweedfs-db.yaml) and injected to the filer
-with ENV.
-* cert config exists and can be enabled, but not been tested.
-
-## Prerequisites
-### Database
-A running MySQL-compatible database is expected by default, as specified in the `values.yaml` at `filer.extraEnvironmentVars`. 
-This database should be pre-configured and initialized by running:
-```sql
-CREATE TABLE IF NOT EXISTS filemeta (
-  dirhash     BIGINT               COMMENT 'first 64 bits of MD5 hash value of directory field',
-  name        VARCHAR(1000) BINARY COMMENT 'directory or file name',
-  directory   TEXT BINARY          COMMENT 'full path to parent directory',
-  meta        LONGBLOB,
-  PRIMARY KEY (dirhash, name)
-) DEFAULT CHARSET=utf8;
-```
-
-Alternative database can also be configured (e.g. leveldb) following the instructions at `filer.extraEnvironmentVars`.
-
-### Node Labels
-Kubernetes node have labels which help to define which node(Host) will run which pod:
-* s3/filer/master needs the label **sw-backend=true**
-* volume need the label **sw-volume=true**
-
-to label a node to be able to run all pod types in k8s:
-```
-kubectl label node YOUR_NODE_NAME sw-volume=true,sw-backend=true
-```
-
-on production k8s deployment you will want each pod to have a different host,
-especially the volume server & the masters, currently all pods (master/volume/filer)
-have anti-affinity rule to disallow running multiple pod type on the same host.
-if you still want to run multiple pods of the same type (master/volume/filer) on the same host
-please set/update the corresponding affinity rule in values.yaml to an empty one:
-
-```affinity: ""```
-
-## PVC - storage class ###
-
-on the volume stateful set added support for K8S PVC, currently example
-with the simple local-path-provisioner from Rancher (comes included with k3d / k3s)
-https://github.com/rancher/local-path-provisioner
-
-you can use ANY storage class you like, just update the correct storage-class
-for your deployment.
-
-## current instances config (AIO):
-1 instance for each type (master/filer+s3/volume)
-
-you can update the replicas count for each node type in values.yaml,
-need to add more nodes with the corresponding labels.
-
-most of the configuration are available through values.yaml
