-## Using aws-sdk-go with Minio
-
-aws-sdk-go is the official AWS SDK for the Go programming language. This document covers
-how to use aws-sdk-go with Minio server.
-
-### Install AWS SDK S3 service
-
-```sh
-$ go get github.com/aws/aws-sdk-go/service/s3
-```
-
-### List all buckets on Minio
-
-```go
-package main
-
-import (

-
-	"github.com/aws/aws-sdk-go/aws"
-	"github.com/aws/aws-sdk-go/aws/credentials"

-	"github.com/aws/aws-sdk-go/service/s3"
-)

-func main() {
-	newSession := session.New()
-	s3Config := &aws.Config{
-		Credentials: credentials.NewStaticCredentials("<YOUR-ACCESS-KEY-ID>", "<YOUR-SECRET-ACCESS-KEY", ""),
-		Endpoint:         aws.String("http://localhost:9000"),
-		Region:           aws.String("us-east-1"),
-		DisableSSL:       aws.Bool(true),
-		S3ForcePathStyle: aws.Bool(true),
-	}
-	// Create an S3 service object in the default region.
-	s3Client := s3.New(newSession, s3Config)
-
-	cparams := &s3.CreateBucketInput{
-		Bucket: aws.String("newbucket"), // Required
-	}
-	_, err := s3Client.CreateBucket(cparams)
-	if err != nil {
-		// Message from an error.
-		fmt.Println(err.Error())
-		return
-	}
-
-	var lparams *s3.ListBucketsInput
-	// Call the ListBuckets() Operation
-	resp, err := s3Client.ListBuckets(lparams)
-	if err != nil {
-		// Message from an error.
-		fmt.Println(err.Error())
-		return
-	}
-
-	// Pretty-print the response data.
-	fmt.Println(resp)

-Populate your AccessKeyId and SecretAccessKey credentials and run the program as shown below.
-
-```sh
-$ go run aws-sdk-minio.go
-{
-  Buckets: [{
-      CreationDate: 2015-10-22 01:46:04 +0000 UTC,
-      Name: "newbucket"

-## Minio Browser
-
-Minio Browser uses Json Web Tokens to authenticate JSON RPC requests.
-
-Initial request generates a token for 'AccessKey' and 'SecretKey'
-provided by the user.
-
-<blockquote>
-Currently these tokens expire after 10hrs, this is not configurable yet.
-</blockquote>
-
-### Start minio server
-
-```
-minio server <testdir>
-```
-
-### JSON RPC APIs.
-
-JSON RPC namespace is `Web`.
-
-#### Auth Operations
-
-* Login - waits for 'username, password' and on success replies a new Json Web Token (JWT).
-* ResetToken - resets token, requires password and token.
-* Logout - currently a dummy operation.
-
-#### Bucket/Object Operations.
-
-* ListBuckets - lists buckets, requires a valid token.
-* ListObjects - lists objects, requires a valid token.
-* MakeBucket - make a new bucket, requires a valid token.
-* GetObjectURL - generates a URL for download access, requires a valid token.
-  (generated URL is valid for 1hr)
-* PutObjectURL - generates a URL for upload access, requies a valid token.
-  (generated URL is valid for 1hr)
-
-#### Server Operations. 
-* DiskInfo - get backend disk statistics.

-### Install Golang
-
-If you do not have a working Golang environment setup please follow [Golang Installation Guide](./INSTALLGO.md).
-
-### Setup your Minio Github Repository
-Fork [Minio upstream](https://github.com/minio/minio/fork) source repository to your own personal repository. Copy the URL and pass it to ``go get`` command. Go uses git to clone a copy into your project workspace folder.
-```sh
-$ mkdir -p $GOPATH/src/github.com/minio
-$ cd $GOPATH/src/github.com/minio
-$ git clone https://github.com/$USER_ID/minio
-$ cd minio
-```
-
-### Compiling Minio from source
-Minio uses ``Makefile`` to wrap around some of redundant checks done through command line.
-
-```sh
-$ make
-Checking if proper environment variables are set.. Done
-...
-Checking dependencies for Minio.. Done
-Installed govet
-Building Libraries
-...
-...
-```
-
-### Setting up git remote as ``upstream``
-```sh
-$ cd $GOPATH/src/github.com/minio/minio
-$ git remote add upstream https://github.com/minio/minio
-$ git fetch upstream
-$ git merge upstream/master
-...
-...
-$ make
-Checking if proper environment variables are set.. Done
-...
-Checking dependencies for Minio.. Done
-Installed govet
-Building Libraries
-...
-```
-
-###  Developer Guidelines
-``Minio`` community welcomes your contribution. To make the process as seamless as possible, we ask for the following:
-* Go ahead and fork the project and make your changes. We encourage pull requests to discuss code changes.
-    - Fork it
-    - Create your feature branch (git checkout -b my-new-feature)
-    - Commit your changes (git commit -am 'Add some feature')
-    - Push to the branch (git push origin my-new-feature)
-    - Create new Pull Request
-
-* If you have additional dependencies for ``Minio``, ``Minio`` manages its depedencies using [govendor](https://github.com/kardianos/govendor)
-    - Run `go get foo/bar`
-    - Edit your code to import foo/bar
-    - Run `make pkg-add PKG=foo/bar` from top-level directory
-
-* If you have dependencies for ``Minio`` which needs to be removed
-    - Edit your code to not import foo/bar
-    - Run `make pkg-remove PKG=foo/bar` from top-level directory
-
-* When you're ready to create a pull request, be sure to:
-    - Have test cases for the new code. If you have questions about how to do it, please ask in your pull request.
-    - Run `make verifiers`
-    - Squash your commits into a single commit. `git rebase -i`. It's okay to force update your pull request.
-    - Make sure `go test -race ./...` and `go build` completes.
-
-* Read [Effective Go](https://github.com/golang/go/wiki/CodeReviewComments) article from Golang project
-    - `Minio` project is fully conformant with Golang style
-    - if you happen to observe offending code, please feel free to send a pull request

-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.

-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing

-
-### To manage dependencies
-
-#### Add new dependencies
-
-  - Run `go get foo/bar`
-  - Edit your code to import foo/bar
-  - Run `govendor add foo/bar` from top-level folder
-
-#### Remove dependencies 
-
-  - Run `govendor remove foo/bar`
-
-#### Update dependencies
-
-  - Run `govendor remove +vendor`
-  - Run to update the dependent package `go get -u foo/bar`
-  - Run `govendor add +external`
-
-### Making new releases 
-
-`minio` doesn't follow semantic versioning style, `minio` instead uses the release date and time as the release versions.
-
-`make release` will install new released binary into your `GOPATH`

+# SILO repository cards
 
-Minio is a distributed object storage server written in Golang. Source is available under free software / open source [Apache license 2.0](./LICENSE). API compatible with Amazon S3 cloud storage service.
+Generated by [Repository Cards](https://github.com/pgsty/silo/actions/workflows/repository-cards.yml)
+at 00:00 UTC daily (08:00 Asia/Shanghai). GitHub may queue scheduled runs.
 
-## Description
+Snapshot: 2026-10-05. 3,838 stars; 58 community contributors.
 
-Micro services environment provisions one Minio server per application instance. Scalability is achieved through large number of smaller personalized instances. This version of the Minio binary is built using Filesystem storage backend for magnetic and solid state disks.
+- `contributors-light.svg` / `contributors-dark.svg`: human issue and PR authors across the SILO project scope, plus reviewed acknowledgements. Bots are excluded. Gold rings follow the reviewed companion-site roster; new authors are collected automatically.
+- `star-history-light.svg` / `star-history-dark.svg`: initial history reconstructed from the then-current stargazers; later points are daily observed totals, including decreases. Missing days are not fabricated.
+- `curated.json`: a cache of reviewed contributor credit from `pgsty/silo.pgsty.com/data/home/contributors.yaml`. The approved initial preview may be newer than the published site; a newer reviewed snapshot is retained until the site catches up.
+- `contributors.json`: generated contributor data and embedded raster avatars. Failed avatar refreshes use the previous image, or an initial when no image is available.
+- `history.json`: persistent daily totals. Keep this file when regenerating images.
