 +===== Building Git =====
 +
 +In Ubuntu, get some dev libs first:
 +
 +<code bash>
 +sudo apt-get install libssl-dev libcurl4-gnutls-dev gettext
 +</code>
 +There was [[https://lore.kernel.org/git/xmqq5xg2wrd1.fsf@gitster.g/|a security fix in 2.50.1]], so here we get that one:
 +<code bash>
 +git clone --filter=blob:none -b v2.50.1 --single-branch --no-tags https://github.com/git/git
 +# or: git clone --branch v2.50.1 --depth 1 https://github.com/git/git
 +# or even: wget https://www.kernel.org/pub/software/scm/git/git-2.50.1.tar.xz
 +
 +make prefix=$HOME/.local -j$(nproc)
 +make prefix=$HOME/.local install
 +</code>
 +
 +This will put git in ''$HOME/.local/bin/''

 +====== Submodules ======
 +
 +[[https://www.cyberdemon.org/2024/03/20/submodules.html|Demystifying git submodules]] is [[https://social.jvns.ca/@b0rk/112604915327918216|summarized by Julia Evans in a 'zine page here]].
 +
 +Cloning a repo doesn't download its submodules. After cloning, run:
 +
 +<code bash>
 +git submodule update --init --recursive
 +</code>
 +
 +Git pull and checkout don't update submodules. To actually update them, you have to run the following every time you switch branches or pull.
 +
 +<code bash>
 +git submodule update --recursive  # Add --init before --recursive on first time
 +</code>

 +====== You Don't Need GitHub ======

 +
 +  * Set "git config receive.denyCurrentBranch updateInstead" Git blocks pushes to active branches by default. This tells it to accept them and update files automatically.
 +  * Create a .git/hooks/post-update that triggers a rebuild or restarts services.
 +  * Tell git to host the remote repo with "git update-server-info"
