+# Local Development
+
+## Informations
+
+If you here youh may be intereset of improve core vuepress.
+
+Vuepress is using a combo with [Yarn workspaces](https://yarnpkg.com/lang/en/docs/workspaces/) and [Lerna](https://github.com/lerna/lerna).
+
+## Init packages
+
+```bash
+ yarn bootstrap // it will run and install into the root all packages subfolders
+```
+
+yarn bootstrap will use hoisting. What it mean for you ?
+
+It will regroup all dependencies in the workspace root and link all packages.
+
+to check the link you can run
+
+```bash
+    ls -la node_modules/@vuepress
+```
+
+You will all symlinks
+
+:::warning
+You have to take care to declare all dependencies inside subFolders package.json. When publish the lib if dependencie from a package is not declare it will just not work.
+:::
+
+:::warning
+There is a special package you should have a look is @vuepress/shared-utils that are in typescript.
+:::
+
+After install everything it will run `yarn tsc`. This command will tell to @vuepress/shared-utils workspace to compile his js.
+
+:::warning
+From here if you are making change inside this package you will have to
+run `yarn tsc` all the time or run in separate shell `yarn run tsc -w`. This will re run tsc at any change from shared-utils
+:::
+
+## Link
+
+Good from here you have everything ready. You need to link vuepress to your project.
+
+```bash
+yarn register-vuepress
+```
+
+You will have something like this: `success Registered "vuepress".`
+
+It will link the package vuepress from packages/vuepress. So you will have access to vuepress cli and vuepress packages.
+
+they are decalre in the `packages/vuepress/package.json`
+
+```js
+{
+"main": "index.js",
+///
+"bin": {
+    "vuepress": "cli.js"
+  }
+  ///
+}
+```
+
+Now go to your project and run `yarn link vuepress`.
+
+You should have it `success Using linked package for "vuepress".`
+
+## Unlink
+
+You may want to unlink everything. For it in the workspace root folder. Run
+
+```bash
+yarn unregister-vuepress
+```
+
+Now you can run `yarn unlink vuepress` into your project folder.
+
+If everything work properly you should have an error telling you there is no package found called vuepress, if you run `yarn link vuepress` in you project folder.
+
+## BUGS / QA
+
+You will maybe find some difficulty with link. If you encounter something like `There's already a package called "vuepress" registered`.
+You have already vuepress registered. so:
+
+- if you already link vuepress from [Link](#link). It's totally fine. If you make changes because it is symlink you dont have to re run something. You will have to rerun yarn tsc if you update shared-utils package. Nothing more
+- if you have done nothing. You have already vuepress linked somewhere. What you have to do is to delete folder where you already run `yarn link` or run `yarn unlink` inside it.
+
+## More
+
+You will have interesting commands available:
+
+- `yarn packages:list` will list you every packages present and their versions [More...](https://github.com/lerna/lerna/tree/master/commands/list#readme)
+- `yarn packages:changed` will tell you which package will be affect by the next lerna publish / version [More...](https://github.com/lerna/lerna/tree/master/commands/changed#readme)
+- `yarn packages:diff` will show you all diff from last release [More...](https://github.com/lerna/lerna/tree/master/commands/diff#readme)
