## Prerequisite
{{< gomodules-info >}}
## Initialize a New Module
Use `hugo mod init` to initialize a new Hugo Module. If it fails to guess the module path, you must provide it as an argument, e.g.:
```bash
hugo mod init github.com/gohugoio/myShortcodes
```
Also see the [CLI Doc](/commands/hugo_mod_init/).
## Update Modules
Modules will be downloaded and added when you add them as imports to your configuration, see [Module Imports](/hugo-modules/configuration/#module-config-imports).
To update or manage versions, you can use `hugo mod get`.
Some examples:
### Update All Modules
```bash
hugo mod get -u
```
### Update All Modules Recursively
{{< new-in "0.65.0" >}}
```bash
hugo mod get -u ./...
```
### Update One Module
```bash
hugo mod get -u github.com/gohugoio/myShortcodes
```
### Get a Specific Version
```bash
hugo mod get github.com/gohugoio/myShortcodes@v1.0.7
```
Also see the [CLI Doc](/commands/hugo_mod_get/).
## Make and test changes in a module
One way to do local development of a module imported in a project is to add a replace directive to a local directory with the source in `go.mod`:
```bash
replace github.com/bep/hugotestmods/mypartials => /Users/bep/hugotestmods/mypartials
```
If you have the `hugo server` running, the configuration will be reloaded and `/Users/bep/hugotestmods/mypartials` put on the watch list.
## Print Dependency Graph
Use `hugo mod graph` from the relevant module directory and it will print the dependency graph, including vendoring, module replacement or disabled status.
E.g.:
```
hugo mod graph
github.com/bep/my-modular-site github.com/bep/hugotestmods/mymounts@v1.2.0
github.com/bep/my-modular-site github.com/bep/hugotestmods/mypartials@v1.0.7
github.com/bep/hugotestmods/mypartials@v1.0.7 github.com/bep/hugotestmods/myassets@v1.0.4
github.com/bep/hugotestmods/mypartials@v1.0.7 github.com/bep/hugotestmods/myv2@v1.0.0
DISABLED github.com/bep/my-modular-site github.com/spf13/hyde@v0.0.0-20190427180251-e36f5799b396
github.com/bep/my-modular-site github.com/bep/hugo-fresh@v1.0.1
github.com/bep/my-modular-site in-themesdir
```
Also see the [CLI Doc](/commands/hugo_mod_graph/).
## Vendor Your Modules
`hugo mod vendor` will write all the module depencies to a `_vendor` folder, which will then be used for all subsequent builds.
Note that:
* You can run `hugo mod vendor` on any level in the module tree.
* Vendoring will not store modules stored in your `themes` folder.
* Most commands accept a `--ignoreVendor` flag, which will then run as if the none of the `_vendor` folders in the module tree existed.
Also see the [CLI Doc](/commands/hugo_mod_vendor/).
## Tidy go.mod, go.sum
Run `hugo mod tidy` to remove unused entries in `go.mod` and `go.sum`.
Also see the [CLI Doc](/commands/hugo_mod_clean/).
## Clean Module Cache
Run `hugo mod clean` to delete the entire modules cache.
Note that you can also configure the `modules` cache with a `maxAge`, see [File Caches](/hugo-modules/configuration/#configure-file-caches).
Also see the [CLI Doc](/commands/hugo_mod_clean/).
