+## Installation
+
 The   tool  doesn't   need   authentication  and   doesn't  have   any
 dependencies.  Just  download the  binary for  your platform  from the
 releases page and you're good to go.
 
-The releases also include a handy tarball which you can use to install
+### Installation using a pre-compiled binary
-the tool  system-wide including the  manual page. Just extract  it and
+
-type: `make install`.
+Go            to             the            [latest            release
+page](https://github.com/TLINDEN/kleingebaeck/releases/latest)     and
+look for your OS and platform. There are two options to install the binary:
+
+1.    Directly   download    the    binary    for   your    platoform,
+   e.g. `kleingebaeck-linux-amd64-0.0.5`, rename  it to `kleingebaeck`
+   (or  whatever  you  like  more!)  and put  it  into  your  bin  dir
+   (e.g. `$HOME/bin` or as root to `/usr/local/bin`).
+
+Be sure to verify the signature of the binary file. For this also download the matching `kleingebaeck-linux-amd64-0.0.5.sha256` file and:
+
+```shell
+cat kleingebaeck-linux-amd64-0.0.5.sha25 && sha256sum kleingebaeck-linux-amd64-0.0.5
+```
+You should see the same SHA256 hash.
+
+2.  You  may  also  download  a  binary  tarball  for  your  platform,
+   e.g.  `kleingebaeck-linux-amd64-0.0.5.tar.gz`,  unpack and  install
+   it. GNU Make is required for this:
+   
+```shell
+tar xvfz kleingebaeck-linux-amd64-0.0.5.tar.gz
+cd kleingebaeck-linux-amd64-0.0.5
+sudo make install
+```
+
+### Installation from source
+
+You will need the Golang toolchain  in order to build from source. GNU
+Make will also help but is not strictly neccessary.
+
+If you want to compile the tool yourself, use `git clone` to clone the
+repository.   Then   execute   `go    mod   tidy`   to   install   all
+dependencies. Then  just enter `go  build` or -  if you have  GNU Make
+installed - `make`.
+
+To install after building either copy the binary or execute `sudo make install`.

+## Related projects
+
+I could not find any projects specifically designed to backup
+kleinanzeigen.de ads, however there's a bot project which is also able
+to download ads:
+[kleinanzeigen-bot](https://github.com/Second-Hand-Friends/kleinanzeigen-bot/). However,
+be aware that kleinanzeigen.de is actively fighting bots! Look at this
+[issue](https://github.com/Second-Hand-Friends/kleinanzeigen-bot/issues/219). The
+problem with these kind of bots is, that they login into your account
+using your credentials. If the company is able to detect bot activity
+they can associate it easily with your account and **lock you
+out**. So be careful.
+
+**kleingebäck** doesn't need to login, it just accesses public
+available web pages. Kleinanzeigen.de could hardly do anything against
+it, once because it is legal. There's no difference between a browser
+and a commandline client. Both run on the clientside and it is not
+kleinanzeigen.de's decision which software one uses to access their
+pages. And second: because you can use it to download any ads, not
+just yours. So it is not really clear if the activity is associated in
+any way with the ad owner. In addition to that comes the fact that
+kleingebäck is just a backup tool. It is not intendet to be used on a
+daily basis. You cannot use it to view regular ads or maintain your
+own ads. You'll need to use the mobile app or the browser page with a
+login. So, in my point of view, the risk is very minimal.
+
+There is another Tool available named [kleinanzeigen-enhanded](https://kleinanzeigen-enhanced.de/). It is a complete Ad management system targeting primarily commercial users. You have to pay a monthly fee, perhaps there's also a free version available, but I haven't checked. The tool is implemented as a Chrome browser extension, which explains why it was possible to implement it without an API. It seems to be a nice solution for power users by the looks of it. And it includes backups.
