+
+## Installation
+
+Get the **prebuilt `.eap` file** from the [Releases page](https://github.com/Mo3he/Axis_Cam_Tailscale/releases).
+
+1. Log into your Axis camera.  
+2. Go to **Apps → Add App**.  
+3. Upload the `.eap` file.  
+
+Once installed:
+- Start the app. 
+- Click **Open** to view logs and get your Tailscale authentication URL.  
+- On uninstall, all changes/files are removed.  
+
+> You'll need a [Tailscale account](https://tailscale.com/) to authenticate.
+
+---
+
+## Usage
+
+- Runs a C-based parameter bridge (compiled via ACAP SDK 1.15.1) that reads settings from the ACAP parameter store and launches Tailscale.  
+- View logs and connection status via the **Open** button in the app.  
+- Authenticate using the provided URL, or pre-enter an auth key in **Settings**.  
+- Change the **Custom Server URL** in Settings to use a self-hosted [Headscale](https://headscale.net/) control server.
+- Parameter changes (ports, server URL, auth key) are applied automatically without needing to reinstall the app.
+
+---
+
+## Settings
+
+All parameters are configurable via the web UI (**Open → Settings** card) and take effect immediately without reinstalling:
+
+| Parameter | Default | Description |
+|---|---|---|
+| Custom Server URL | *(empty)* | Control server URL for [Headscale](https://headscale.net/) or other self-hosted servers. Leave blank to use Tailscale's official servers. |
+| Auth Key | *(empty)* | Pre-authentication key (`tskey-auth-...`). Cleared automatically after first successful connection. Leave blank to authenticate via browser. |
+| HTTP Proxy Port | `8080` | Port for the outbound HTTP/HTTPS proxy. |
+| SOCKS5 Proxy Port | `1080` | Port for the outbound SOCKS5 proxy. |
+| Accept DNS | `off` | Passes `--accept-dns=true` to `tailscale up`. Allows the tailnet to push DNS settings to the camera. Off by default to avoid overriding the camera's DNS configuration. Not available on `armv7hf_acap3`. |
+| Accept Routes | `off` | Passes `--accept-routes=true` to `tailscale up`. Allows the camera to use subnet routes advertised by other nodes in the tailnet. Not available on `armv7hf_acap3`. |
+
+---
+
+
+All non-ROOT variants expose two local proxy endpoints that route outbound traffic through the Tailscale tunnel. The ports are configurable via **Settings → HTTP Proxy Port / SOCKS5 Proxy Port** in the web UI.
+
+### HTTP CONNECT Proxy — `http://127.0.0.1:8080` (default)
+
+Routes HTTP and HTTPS traffic. Set this wherever an HTTP/HTTPS proxy field is available on the camera:
+
+| Location | Field | Value |
+|---|---|---|
+| System → Network → Global proxies | HTTP proxy | `http://127.0.0.1:<port>` |
+| System → Network → Global proxies | HTTPS proxy | `http://127.0.0.1:<port>` |
+| System → MQTT → Broker | HTTP proxy | `http://127.0.0.1:<port>` |
+| System → MQTT → Broker | HTTPS proxy | `http://127.0.0.1:<port>` |
+
+### SOCKS5 Proxy — `127.0.0.1:1080` (default)
+
+For ACAP apps or services that support SOCKS5, set their proxy to `127.0.0.1:<port>`.
+
+> The active proxy addresses are always shown in the **Proxy Configuration** card of the web UI.
+
+> If you change a port that is already in use by another process, the app will log an error and exit rather than silently falling back to a different port.
+
+---
+
+## Updating Tailscale
+
+- New `.eap` files are auto-built and released **weekly** (if a new Tailscale version is available).  
+- To update, simply install the new `.eap` over the existing one.  
+
+### Manual update (advanced)
+
+Replace the binaries in the `lib/` folder:
+- `tailscale`
+- `tailscaled`
+
+Download the latest versions: [Tailscale static builds](https://pkgs.tailscale.com/stable/#static)
+
+#### Build locally
+
+From the main directory of the version you want (`arm` / `aarch64`):
+
+```bash
+docker build --tag <package_name> .
+docker cp $(docker create <package_name>):/opt/app ./build
+```
+
+---
+
+## Good News
+
+Tailscale ACAP can now run **without root privileges**, making it compatible with **Axis OS 11.11+**.  
+
+- Runs in **user space networking mode**.  
+
+For **full kernel networking**, use the **ROOT** version. Note: ROOT mode requires Axis OS 11.11–11.x — Axis OS 12 and later removed root access for third-party applications.
+
+### Legacy camera support (Axis OS 9.x / 10.x)
+
+An **ACAP 3** variant (`armv7hf_acap3`) is available for older cameras that do not support ACAP 4 / Axis OS 11+. It uses the same userspace networking mode and web UI, built against the ACAP SDK 3.5 toolchain.
+
+---
 
 ## Purpose
 
-Adding a VPN client directly to the camera allows secure remote access to the device without requiring any other equipment or network configuration.
-Tailscale achieves this in a secure, simple to setup and easy to use way.
-Tailscale is based on WireGuard VPN tunneling technology.
+Adding a VPN client directly to the camera enables:  
+- Secure remote access without additional hardware or complex network configuration.  
+- Easy setup through Tailscale’s lightweight WireGuard-based tunnel.

 ## Compatibility
 
-The Tailscale ACAP is compatable with Axis cameras with arm and aarch64 based Soc's.
+The Tailscale ACAP is compatible with Axis cameras with **ARM** and **AARCH64**-based SoCs.
 
-```
-curl --anyauth "*" -u <username>:<password> <device ip>/axis-cgi/basicdeviceinfo.cgi --data "{\"apiVersion\":\"1.0\",\"context\":\"Client defined request ID\",\"method\":\"getAllProperties\"}"
+| Variant | Architecture | Axis OS | Notes |
+|---|---|---|---|
+| `aarch64` | AArch64 | 11.11+ (ACAP 4) | Standard, userspace networking, configurable proxy ports |
+| `armv7hf` | ARMv7 | 11.11+ (ACAP 4) | Standard, userspace networking, configurable proxy ports |
+| `aarch64_root` | AArch64 | 11.11 – 11.x (ACAP 4) | Full kernel networking (root) — not supported on OS 12+ |
+| `armv7hf_root` | ARMv7 | 11.11 – 11.x (ACAP 4) | Full kernel networking (root) — not supported on OS 12+ |
+| `armv7hf_acap3` | ARMv7 | **9.x – 10.x** | Legacy cameras, ACAP SDK 3 |
+
+> Not sure which variant to use? Check **System → Properties → Firmware version** on your camera. Axis OS 12+ → use the standard variant (`aarch64` or `armv7hf`). Axis OS 11.11–11.x → standard variant, or ROOT if you need kernel networking. Axis OS 9.x/10.x on ARMv7 → use `armv7hf_acap3`.
+
+You can verify your device details using the following command:
+
+```bash
+curl --anyauth "*" -u <username>:<password> <device_ip>/axis-cgi/basicdeviceinfo.cgi --data '{"apiVersion":"1.0","context":"Client defined request ID","method":"getAllProperties"}'
 ```
 
-where `<device ip>` is the IP address of the Axis device, `<username>` is the root username and `<password>` is the root password. Please
-note that you need to enclose your password with quotes (`'`) if it contains special characters.
+> Replace `<device_ip>`, `<username>`, and `<password>` with your device credentials.  
+> Enclose your password in quotes `' '` if it contains special characters.
 
-## Installing
+---
 
-The recommended way to install this ACAP is to use the pre built eap file.
-Go to "Apps" on the camera and click "Add app".
+## Roadmap
 
+### AXIS OS 13 Preparation
 
-## Using the Tailscale ACAP
+AXIS OS 13 (scheduled for September 2026) introduces several breaking changes that affect all ACAP applications. The following items are required to maintain compatibility. See the full [AXIS OS 13 breaking changes](https://www.axis.com/for-developers/news/AXIS-OS-13-breaking-changes) announcement for details.
 
-The Tailscale ACAP will run a script on startup that sets the required permissions and starts the service and app.
-Once started click "Open" to see the output of the logs for further instructions and obtain the authetication URL.
+- [ ] **Recompile for 64-bit time (Y2038)** - AXIS OS 13 switches to a 64-bit time interface. All ACAP apps must be recompiled against the updated SDK. Cameras with incompatible apps installed will roll back the OS upgrade rather than proceed.
+- [ ] **Sign the ACAP via the Axis ACAP Portal** - AXIS OS 13 removes the ability to install unsigned applications in production environments. The app must be submitted and signed through the official Axis ACAP Portal to remain installable.
+- [ ] **Migrate to Manifest Schema v2** - The `manifest.json` must use Manifest Schema v2, including an explicit declaration of compatible AXIS OS versions, to satisfy the new signing and compatibility requirements.
+- [ ] **Audit for executable stack usage** - Any ACAP compiled with an executable stack must be recompiled to comply with the new security restrictions in AXIS OS 13.
+- [ ] **Verify web UI works over HTTPS** - AXIS OS 13 enforces HTTPS-only connections by default. The bundled web UI must be tested to confirm it functions correctly under this constraint.
 
-When uninstalling the ACAP, all changes and files are removed from the camera.
+### General Improvements
 
-You will need a tailscale.com account to use the ACAP
+- [x] **Accept DNS from tailnet toggle** - Add an opt-in setting to the settings page that passes `--accept-dns=true` to `tailscale up`. Defaults to off to prevent Tailscale from overriding `resolv.conf` on cameras that don't need MagicDNS.
+- [x] **Accept routes toggle** - Add an opt-in setting that passes `--accept-routes=true` to `tailscale up`, allowing the camera to use subnet routes advertised by other nodes in the tailnet.
+- [ ] **Switch to tiny-tailscale binaries** - Evaluate replacing the bundled `tailscale` and `tailscaled` binaries with [tiny-tailscale](https://github.com/iamromulan/tiny-tailscale) builds. These combine both into a single binary, strip unused features, and are significantly smaller (~43% reduction), reducing install size and memory footprint across all architectures.
 
-## Updating Tailscale version
-
-The eap files will be updated from time to time and simply installing the new version over the old will update all files.
-
-It's also possible to build and use a locally built image as all necesary files are provided.
-
-Replace binaries "tailscale" and "tailscaled" in lib folder with new versions.
-Make sure you use the files for the correct Soc.
-
-Latest versions can be found at 
-
-https://pkgs.tailscale.com/stable/#static
-
-
-To build, 
-From main directory of the version you want (arm/aarch64)
-
-```
-docker build --tag <package name> . 
-```
-```
-docker cp $(docker create <package name>):/opt/app ./build

+ * ACAP parameter bridge for Tailscale VPN (userspace variant).
+ *
+ * Responsibilities:
+ *  1. Read Tailscale parameters from the ACAP parameter store (axparameter).
+ *  2. Write them to CONFIG_FILE so the shell script can source them.
+ *  3. Launch the shell script (Tailscale_VPN_run) as a child process.
+ *  4. On any parameter change: rewrite CONFIG_FILE and do a full stop+restart
+ *     of the child so the new config is picked up.
+ *     Rapid changes within 300 ms are coalesced into a single restart.
+ *  5. Watchdog: if the child exits unexpectedly, restart it.
