In order to edit the documentation, you will need to download the source pages of the documentation to your computer. Launchpad uses a version control system known as bzr . There are different methods for getting Bazaar working on your system, depending on which operating system you are using. A good step-by-step guide for Microsoft™ operating systems can be viewed here. If you are using Linux, you will need to install bzr on your system through your package manager, or from source code.
Once you have installed bzr on your system, you will need to download the document source. Just follow this procedure:
Make sure you have Bazaar installed.
Start Bazaar by right-clicking a folder if you are using Windows™ and selecting Bzr Here. If you use Linux, you can just create a folder to hold the document sources. You can place the document source in any folder you like.
To download the latest revision of the DHIS2 documents project type: bzr branch https://bazaar.launchpad.net/%7Edhis2-documenters/dhis2/dhis2-docbook-docs if you are using Linux, or alternatively if you are using Windows™ type the url to the source code repository "http://bazaar.launchpad.net/%7Edhis2-documenters/dhis2/dhis2-docbook-docs"
The download process should start and all the documentation source files will be downloaded to the folder that you specified.
