# Getting started

npm install email@example.com -g.
When it's done, generate a new empty project
strapi new myNewProject (don't pay attention to the database configuration).
# Update node modules
Update the Strapi's dependencies version (move Strapi's dependencies to
3.0.0-alpha.21 version) of your project.
npm install firstname.lastname@example.org --save to update your strapi version.
# Update the Admin
If you performed updates in the Admin, you will have to manually migrate your changes.
Delete your old admin folder and replace it with the new one.
# Update the Plugins
If you did a custom update on one of the plugins, you will have to manually migrate your update.
Copy the fields and relations you had in your
/plugins/users-permissions/config/jwt.json file in the new one.
Then, delete your old
plugins folder and replace it with the new one.
That's all, you have now upgraded to Strapi
