+# ⭐ Create a Certificat and badges
+
+Certificates and badges are proof of success for developers in achieving the development of your application.
+
+1) Access the certificate generator to create a custom certification.
+
+A certificate contains an image, a symbol name and a icon.
+
+{% hint style="info" %}
+The choice of the blockchain and the owner of the NFT ERC721 is made with Metamask: `(polygon)`, `(xdai)` et `(arbitrum)`\
+\
+A list contain all the certificates of the different blockchains.
+{% endhint %}
+

+
+2) Access the badge generator to create a badge.
+
+Click on the three small dots of the certificate and select details for open the certificat détails.
+
+3) Use the badge generator to create a personalized certification badge.
+
+![Create a badge](../.gitbook/assets/certificat\_details.png)
+
+The badge consists of an image and metadata. These will enhance the digital representation of your certification.
+
+The details of a badge can be found by clicking on it.
+
+4) Attribute a badge to a github user in the Github issue of a deal.
+
+**Entitle** it or add a **comment** with this format: _$\<badge\_keyword> \<certificate_symbol> \<badge_name> \ <wallet_address_recipient> or \<@github-user>_.
+
+The delivery request is in a Github comment of a registered repository, and contains the recipient's wallet address.  
+
+For mint with username github preceded by @, open profile, in the top right dropdown menu, login to Metamask and prove ownership performing a signature in Metamask.
+
+![Prove ownership](../.gitbook/assets/badge\_prove\_ownership.png)
+
+{% hint style="info" %}
+The keywords to launch a mint of a badge are these: `$badge`.\
+{% endhint %}
+
+![Mint a badge](../.gitbook/assets/badge\_mint.png)
+
+The one who mint with the returned message must be the ower of certificate on which the badge was edited and have the rights to his wallet address.   
+
+You minted successfully!
+
+5) Delete a certificate belonging to their Github organization.
+
+The certificate can be deleted from the list of certificates. Deleting the certificate will delete the badges corresponding to it.
+
+{% hint style="info" %}
+When the certificate is deleted with its badges, these are kept on the blockchain with their properties and metadata.\
+\
+It is recommended that you save our smart-contract address of certificat to continue using them after this.
+{% endhint %}
+
+Once deleted, the Feature application does not keep them and no longer allows them to be returned to the dashboard.
