 Use [this link](https://alisw.cern.ch/check) to check if your CERN account is connected to ALICE. In case you see a message saying that you are not an ALICE member, you need to fix the problem: many services are not accessible if you are not considered an ALICE member.
 
 Drop an email to the ALICE Secretariat, they will help you: <[email protected]>

+## Do you have access to lxplus?
 When you have a CERN account you can typically login to lxplus via SSH:
-```
+```bash
 ssh [email protected]
 ```
 If, in spite of providing the correct password, you are not allowed to connect, go on your [CERN account management page](https://cern.ch/account). You need to **Sign in** and to select **Resources and Services** like in the picture below:

 Keep at hand the `myCertificate.p12` file you have previously downloaded. You need to convert it into two files (a "certificate" and a "key") in order to use the ALICE Grid services from the command line.
 
 You will export your certificates to the following directory:
-```
+```bash
 ~/.globus
 ```
 
 Now export the certificate with the following command (you will be prompted for the export password you have selected when you have generated it):
-```
+```bash
 openssl pkcs12 -clcerts -nokeys -in ~/Downloads/myCertificate.p12 -out ~/.globus/usercert.pem
 ```
 
 The result will be a file called `usercert.pem` in your `~/.globus` directory. Note that your input file ending with `.p12` may have a different name and may be stored in a different location.
 
 Time to export the **private key**:
-```
+```bash
 openssl pkcs12 -nocerts -in ~/Downloads/myCertificate.p12 -out ~/.globus/userkey.pem
 chmod 0400 ~/.globus/userkey.pem
 ```
 When it says:

 you should provide it with the export password you have entered when you generated it. The next question will be:
-```

 Enter PEM pass phrase:
 ```
 You should provide it with another password that will be used to protect the private key. You can use the same password as before if you want, but please **do not use your CERN password** (yes, we are stressing this point a **lot**). This question will be asked twice for confirmation.
