+Simply place git-build.sh in your path. If you don't know where to put it, the script .git-build/git-build will put it in ~/bin/ and add the folder to your $PATH in ~/.bashrc.

@@ -14,9 +14,27 @@ git-build.sh looks up your ~/.git-build/ folder to find stuff to build:
 - PROJECT.source <-- URL to the git repo for PROJECT
 - PROJECT.branch (optional) <-- branch to checkout
 - PROJECT <-- script to execute when the project is updated
+- PROJECT.log <-- STDOUT of PROJECT last run
+- PROJECT.err <-- STDERR of PROJECT last run
 
 Additionally, for each PROJECT a .PROJECT/ folder is created to clone the repository.
 
+Note: the PROJECT script needs to be executable!

+As an example on how to get started, this repo includes a .git-build/ folder. It's the configuration that generates [this site](https://thunix.net/~southerntofu/rfc) and keeps git-build.sh updated.

+# Auto-update
+
+Yes, you read that correctly. If you copy .git-build/git-build{,.source} to ~/.git-build/ git-build.sh will automatically be updated on each run.
+
+You may not want to do that but i thought that was a nice proof of concept that the updater can update itself.
+
+# Auto-execute
+
+You need CRON for that. Additionally, i'm interested to run this script through a webhook endpoint for Github/Gitlab/Gitea webhooks.

+# Contribute

+Right now it seems to be working. If you find a bug please report it or open a merge request :)
