Here is how you can upload a WordPress plugin on WordPress.org. First, make your plugin ready; consider two key things: the plugin file itself and the readme file. Make sure you follow the guidelines in the readme or simply download one from any plugin if needed. Then, create an assets folder to include banners, icons, and screenshots. Please use the guidelines for sizes and formats. And for screenshots, use name as screenshot-1, screenshot-2, and so on, and add the screenshot name on the readme file.

After organizing your files, compile the plugin as a zip file. Then, visit WordPress.org, log in, and submit a plugin. Then simply upload your files. You will see the pending plugins for reviews and as well the estimated number of days for approval of your plugin. In between the plugin review, you might also receive an email from WordPress for any changes.

Once your plugin is approved, you will receive a congratulations email along with further instructions, including an SVN and plugin URL. Use Tortoise SVN to upload your plugins to WordPress. On Tortoise SVN, check out your SVN repository using the credentials (or check your email for this); you will find empty folders for tags, assets, and trunk. Copy your assets into the assets folder and create the stable version of your plugin in the tags folder, and in the trunk folder keep the plugin files of your stable version. And commit the changes. After uploading all the files successfully you will see your plugin on the WordPress repository.

Thank you very much.
