+# Certifying and Adding Your Plugin to Jami
+
+To add your plugin built on Jami, you need to certify it by signing it with keys and certificates.
+
+First, you will generate a unique developer key and certificate, which will be used to create a certificate for each plugin. Then, you will sign your plugin archive (.jpl) using the plugin’s certificate key.
+
+After that, you will be able to add your signed plugin to Jami.
 
 ## Create a directory to store them:
 
-```
+```bash
 mkdir -p jami-plugins/certificate
 ```
 
-## In a Python environment (recommended) install the requirements:
+## Install the Required Dependencies
 
-```
+Install the necessary dependencies in a Python environment:
+
+```bash
 cd jami-plugins/SDK
 pip install -r requirements.txt
 pip install -r certificate_requirements.txt
 pip install requests
 ```
 
-## Create the certificates:
+## Create the Developer Key and Certificate
 
-```
-python3 ./certKey.py create --subject PluginName ../certificate/
+Generate a unique developer certificate:
+
+```bash
+./certKey.py create --subject <YourName> ../certificate/<YourName>
 ```
 
-## Verify the certificates:
+## Create the Plugin Certificate
 
-```
-openssl x509 -in ../certificate/certificate.crt -text -noout
+Use the developer certificate to create a plugin-specific certificate:
+
+```bash
+./certKey.py create --issuer ../certificate/<YourName> --subject <YourPlugin> ../certificate/<YourPlugin>
 ```
 
-## Sign the plugin (certKey.py will automatically add the `.crt` and `.jpl` extensions):
+## Verify the Certificates
 
-```
-python3 ./certKey.py --plugin sign --issuer <Path to your certificate without the ".crt"> --path <path to your plugin.jpl> <path to your signed plugin output without the ".jpl">
+To verify the content of a certificate:
+
+```bash
+openssl x509 -in ../certificate/<CertificateName.crt> -text -noout
 ```
 
-For example:
+## Sign the Plugin
 
+Sign your plugin archive using the created certificate:
+
+```bash
+python3 ./certKey.py --plugin sign --issuer ../certificate/<YourPlugin> --path ../build/<your distribution>/<YourPlugin.jpl> ../build/<your distribution>/signed/<YourPluginSigned>
 ```
-python3 ./certKey.py --plugin sign --issuer ../certificate/certificate --path ../build/x86_64-linux-gnu/AutoAnswer.jpl ../build/x86_64-linux-gnu/signed/AutoAnswerSigned
-```
 
-## Display the signed files:
+## Complete example with developer=Alexandre, plugin=AudioFilter, distribution=x86_64-linux-gnu:
+
+```bash
+python3 ./certKey.py create --subject Alexandre ../certificate/Alexandre
 
+python3 ./certKey.py create --issuer ../certificate/Alexandre --subject AudioFilter ../certificate/AudioFilter
+
+python3 ./certKey.py --plugin sign --issuer ../certificate/AudioFilter --path ../build/x86_64-linux-gnu/AudioFilter.jpl ../build/x86_64-linux-gnu/signed/AudioFilterSigned
 ```
+
+## Display the Signed Files
+
+Verify that the signed file is generated correctly:
+
+```bash
 ls ../build/<your distribution>/signed
 ```
 
-## You can now add your signed `.jpl` plugin to Jami.
