+
+## Installation
+
+You can install sreg by following these steps:
+
+1. Download the latest version of the sreg release package for your operating system: [sreg](https://github.com/labring/sreg/releases)

+   ```sh
+   sudo mv sreg /usr/local/bin/
+   ```
+
+## Usage
+
+### Save an Image to a Local File
+```sh
+sreg save --registry-dir=/tmp/registry1 my-context
+```
+
+### Start a Filesystem Image Repository Service
+```sh
+sreg serve filesystem --port=5000
+```
+
+### Start an In-Memory Image Repository Service
+```sh
+sreg serve inmem --port=5000
+```
+
+### Sync an Image to a Different Repository
+```sh
+sreg sync source-image dst
+```
+
+### Copy an Image to a Different Repository
+```sh
+sreg copy source-image dst
+```
+
+## Building Your Own Version
+
+If you wish to build your own version of sreg, you can use [goreleaser](https://goreleaser.com/) for building. Use the following command to build:
+
+```sh
+goreleaser build --snapshot --timeout=1h --rm-dist
