 # Build a private mirror
 
-When building a private cloud, it is common to use an isolated network environment where the official mirror of TiUP is not accessible, so we provide a solution for building a private mirror, which is mainly implemented by the mirros component, which can also be used for offline deployment.
+When building a private cloud, it is common to use an isolated network environment where the official mirror of TiUP is not accessible, so we provide a solution for building a private mirror, which is mainly implemented by the mirrors component, which can also be used for offline deployment.
 
 ## Mirrors component introduction
 
 First, let's look at the `mirrors' help file.
 
 ```bash
-$ tiup mirrors --help
-Starting component `mirrors`: /Users/joshua/.tiup/components/mirrors/v0.0.1/mirrors
-Build a local mirrors and download all selected components
+$ tiup mirror --help
+The 'mirror' command is used to manage a component repository for TiUP, you can use
+it to create a private repository, or to add new component to an existing repository.
+The repository can be used either online or offline.
+It also provides some useful utilities to help managing keys, users and versions
+of components or the repository itself.
 
 Usage:

 Then this order has very scary dozens of flags and even more later. But there is no need to be intimidated by the number of these flags, which are in fact of four types.

 ### 3. Platform limitation
 
 If you only want to clone packages for a particular platform, you can use `-os` and `-arch` to qualify:
-- `tiup mirros <target-dir> ---os=linux`
-- Just want to clone amd64 architecture: `tiup mirros <target-dir> --arch=amd64`
-- Just want to clone linux/amd64: `tiup mirros <target-dir> --os=linux --arch=amd64`

+- Just want to clone linux/amd64: `tiup mirror <target-dir> --os=linux --arch=amd64`
 
 ### 4. Component version limited
 
 If you want to clone only one version of a component and not all versions, use `--<component>=<version>` to qualify, for example "
-- Just want to clone the v4 version of tidb: `tiup mirrors <target-dir> --tidb v4`
-- Just want to clone the v4 version of tidb, and all versions of tikv: `tiup mirros <target-dir> --tidb v4 --tikv all`

 For example, if we want to install a v4.0.0-rc TiDB cluster in an isolated environment, we can execute the following command on a machine connected to the extranet to pull the required components:
 
 ```bash
-tiup mirrors package --os=linux v4.0.0-rc

 This command creates a directory called `package` in the current directory that contains the package of components necessary to start a cluster, which is then packaged by the tar command and sent to a central control unit in an isolated environment:
