@@ -4,5 +4,33 @@ A personal project to create a decent git prompt in Rust.
 # Background
 I need a replacement for the quite nice bash git prompt, which is just too slow on Windows.  Also I like to use other shells on Windows including `cmd` and `tcc`. And this has become an opportunity for me to learn Rust.
 
+# Usage
+
+### bash
+E.g., here's what I'm using right now...
+```
+# Setup variables for the binary and the non-git portions of the prompt
+export GIT_PROMPT_BINARY=<path to git_prompt binary>
+export GIT_PROMPT_START="${COLOR_GRAY}\T ${COLOR_BLUE}\h:${COLOR_GREEN}\w${COLOR_NONE} "
+export GIT_PROMPT_END="\n>"
+
+# This is executed by bash before each prompt, and it resets PS1 to
+# be updated based upon the current state of the shell, assuming
+# GIT_PROMPT_BINARY is valid.
+set_prompt() {
+  if [[ -e $GIT_PROMPT_BINARY ]]; then
+    export PS1="${GIT_PROMPT_START}`${GIT_PROMPT_BINARY}`${GIT_PROMPT_END}"
+  fi
+}
+export PROMPT_COMMAND='set_prompt'
+```
+
+### TCC
+E.g., here's what I'm using right now...
+```
+SET GIT_PROMPT_BINARY=<path to git_prompt binary>
+prompt `$e[1;30m$M $e[0;34m%COMPUTERNAME $e[0;32m$P$e[0m %@execstr[%GIT_PROMPT_BINARY]$_$g`
+```
