+## Integrate into editors
+
+### Zed
+
+To integrate flatplay in Zed you can define custom tasks and key bindings.
+
+Add the following tasks to your `tasks.json` file (you can open it with the `zed: open tasks` action):
+
+```json
+{
+  "label": "build & run flatpak",
+  "command": "flatplay build-and-run"
+},
+{
+  "label": "build flatpak",
+  "command": "flatplay build"
+},
+{
+  "label": "run flatpak",
+  "command": "flatplay run"
+},
+{
+  "label": "stop flatpak",
+  "command": "flatplay stop"
+},
+{
+  "label": "clean flatpak build",
+  "command": "flatplay clean"
+},
+{
+  "label": "update flatpak dependencies",
+  "command": "flatplay update-dependencies"
+},
+{
+  "label": "select flatpak manifest",
+  "command": "flatplay select-manifest"
+}
+```
+
+Next, add new bindings to your `keymaps.json` file (you can open it with the `zed: open keypam` action):
+
+```json
+{
+  "context": "Workspace",
+  "bindings": {
+    "ctrl-alt-b": ["task::Spawn", { "task_name": "build & run flatpak" }],
+    "ctrl-alt-r": ["task::Spawn", { "task_name": "run flatpak" }],
+    "ctrl-alt-c": ["task::Spawn", { "task_name": "stop flatpak" }]
+  }
+},
+```
+
+Then you can run any of the tasks by pressing `Alt-Shift-T`, or use `Ctrl-Alt-B`, `Ctrl-Alt-R` or `Ctrl-Alt-C` to build & run, run or stop flatpaks.

 # Some notes
 
 - A lot of the code is almost directly borrowed from [`flatpak-vscode`](https://github.com/bilelmoussaoui/flatpak-vscode).
