Editing Ubuntu official documentation pages

Maybe I wasn’t rigorous enough in reading the page, but I can’t edit the Ubuntu Wiki Official Documentation.

I logged in using my UbuntuOne Account and using my Launchpad Account but still I can’t edit the page.

Let us take an example on this page: https://help.ubuntu.com/community/MpichCluster

I found an error in the keychain set code instruction on MPICH Cluster arrangement. The instruction asks us to put some code in the ~/.bashrc file. It was written as:

if type keychain >/dev/null 2>/dev/null; then
  keychain --nogui -q id_rsa
  [ -f ~/.keychain/${HOSTNAME}-sh ] && . ~/.keychain/${HOSTNAME}-sh
  [ -f ~/.keychain/${HOSTNAME}-sh-gpg ] && . ~/.keychain/${HOSTNAME}-sh-gpg

We should add fi to complete this code. Otherwise it will give us error. I want to add that fix. I also want to add a comment that this action should be done in the master machine, not in the helper machine (I prefer to use “helper machine” instead of “slave machine”).

Maybe somebody can help to do this. Thank you

OK After some explanation from several community member, I can summarize the step how to edit

Ubuntu official documentation pages

by practice. There are probably other procedures in accordance with this.

(For the official Guidance is just available in https://help.ubuntu.com/community/WikiGuide)

1. Click Login to edit, when you are in the page that you want to edit.
2. Login to or sign up for your Ubuntu One account.
3. Accept your personal data request by clicking Yes, Log me in.
4. After you are redirected to the User Documentation Page, you can search the article you want to edit. It took around 10 second in my case to be redirected.
5. Finally, you will have an edit button to modify the page.

Good day!
