+We have two cloudflare workers that let us serve some assets of this repo
+from Cloudflare.
+
+* `open-source-website-assets` is used for `install.sh`
+* `docs-proxy` is used for `https://zed.dev/docs`
+
+On push to `main`, both of these (and the files they depend on) are uploaded to Cloudflare.
+
+### Deployment
+
+These functions are deployed on push to main by the deploy_cloudflare.yml workflow. Worker Rules in Cloudflare intercept requests to zed.dev and proxy them to the appropriate workers.
+
+### Testing
+
+You can use [wrangler](https://developers.cloudflare.com/workers/cli-wrangler/install-update) to test these workers locally, or to deploy custom versions.

+When the user asks you to suggest edits for a buffer, use a strict template consisting of:
+
+* A markdown code block with the file path as the language identifier.
+* The original code that should be replaced
+* A separator line (`---`)
+* The new text that should replace the original lines
+
+Each code block may only contain an edit for one single contiguous range of text. Use multiple code blocks for multiple edits.
+
+## Example
+
+If you have a buffer with the following lines:
+
+```path/to/file.rs
+fn quicksort(arr: &mut [i32]) {
+    if arr.len() <= 1 {
+        return;
+    }
+    let pivot_index = partition(arr);
+    let (left, right) = arr.split_at_mut(pivot_index);
+    quicksort(left);
+    quicksort(&mut right[1..]);
+}
+
+fn partition(arr: &mut [i32]) -> usize {
+    let last_index = arr.len() - 1;
+    let pivot = arr[last_index];
+    let mut i = 0;
+    for j in 0..last_index {
+        if arr[j] <= pivot {
+            arr.swap(i, j);
+            i += 1;
+        }
+    }
+    arr.swap(i, last_index);
+    i
+}
+```
+
+And you want to replace the for loop inside `partition`, output the following.
+
+```edit path/to/file.rs
+for j in 0..last_index {
+    if arr[j] <= pivot {
+        arr.swap(i, j);
+        i += 1;
+    }
+}
+---
+let mut j = 0;
+while j < last_index {
+    if arr[j] <= pivot {
+        arr.swap(i, j);
+        i += 1;
+    }
+    j += 1;
+}
+```
+
+If you wanted to insert comments above the partition function, output the following:
+
+```edit path/to/file.rs
+fn partition(arr: &mut [i32]) -> usize {
+---
+// A helper function used for quicksort.
+fn partition(arr: &mut [i32]) -> usize {
+```
+
+If you wanted to delete the partition function, output the following:
+
+```edit path/to/file.rs
+fn partition(arr: &mut [i32]) -> usize {
+    let last_index = arr.len() - 1;
+    let pivot = arr[last_index];
+    let mut i = 0;
+    for j in 0..last_index {
+        if arr[j] <= pivot {
+            arr.swap(i, j);
+            i += 1;
+        }
+    }
+    arr.swap(i, last_index);
+    i
+}
+---
