 The target audience of this tool are small entities that need a url shortener. The shortened urls can be publicly resolved but only registered users can create short urls. Every registered user can see all shorted urls but ownly modify its own. Admin users can invite other accounts and edit everything that can be edited (also urls created by other accounts).
 
+So in general this is more a shared short url bookmark webpage than a shorturl service.

-## usage
+## Usage
 
-### setup
+### install binary
+
+The pslink binary can be downloaded from the latest release at: https://github.com/enaut/pslink/releases
+
+These binaries are selfcontained and should run on any linux 64bit system. Just put them where you like them to be and make them executable. A sample install might be:
+
+```bash
+# mkdir -p /opt/pslink
+# wget -o /opt/pslink/pslink https://github.com/enaut/pslink/releases/latest/download/pslink.linux.64bit
+# chmod +x /opt/pslink/pslink
+```
+
+You could now adjust your `PATH` or setup an alias or just call the binary with the full path `/opt/pslink/pslink`
+
+### Install with cargo
+
+Pslink can be compiled and installed with cargo. Setup cargo as guided here: https://doc.rust-lang.org/cargo/getting-started/installation.html
+
+After that install pslink using:
+
+```bash
+$ cargo install pslink
+```
+
+If that succeeds you should now be able to call pslink.
+
+### Build from source
+
+When building manually with cargo you have to have a sqlite database present or build it in offline mode. So on your first build you will most likely need to call:
+
+```bash
+SQLX_OFFLINE=1 cargo run
+# or
+$ export SQLX_OFFLINE=1
+$ cargo run
+```
+
+If pslink is built with `cargo build release --target=x86_64-unknown-linux-musl` everything is embedded and it should be portable to any 64bit linux system.
+Templates and migrations are embedded in the binary so it should run standalone without anything extra.
+
+### Setup
 
 To get Pslink up and running use the commands in the following order:
 
-1. `pslink generate-env` this will generate a `.env` file in the curent directory with the default settings. Edit this file to your liking. You can however skip this step and provide all the parameters via commandline or environmentvariable. It is **not** recommended to provide PSLINK_SECRET with commandline parameters as they can be read by every user on the system.
+1. `pslink generate-env`
-2. `pslink migrate-database` will create a sqlite database in the location specified.
-3. `pslink create-admin` create an initial admin user. As the page has no "register" function this is required to do anything usefull.
-4. `pslink runserver` If everything is set up correctly this command will start the service.

 To update to a newer version execute the commands in the following order
 
 1. stop the service
-2. run `pslink migrate-database`
+2. download and install the new binary
-3. run the server again `pslink runserver`
