Github clone only a sub-directory of a repository

If there is a need to download only a sub-directory of the full Github repo, you can do the following steps to clone the required directory.

• git clone <repo root url> <name of the sub-directory>
• cd <name of sub-directory>
• git filter-branch --prune-empty --subdirectory-filter <path to sub-directory> HEAD 

Ex: Let's say you need to clone the apim-is-as-keymanager-sso directory from https://github.com/wso2/presales-demos GitHub repo. Execute the following commands.

• git clone https://github.com/wso2/presales-demos apim-is-as-keymanager-sso
• cd apim-is-as-keymanager-sso
• git filter-branch --prune-empty --subdirectory-filter apim-is-as-keymanager-sso HEAD 

Happy Coding!
