 HTX is a suite of test tools for stressing system hardware. It is routinely
 used by the test suites under `systest/`. Refer to [README](https://github.com/open-power/HTX)
 
+* SEL to error log conversion procedure:
+
+    Pre-requisite: A Power Linux system is required to build the tools.
+
+    ** Obtaining SEL parser tools: **
+    - Go to https://openpower.xyz/job/openpower-op-build/
+    - Click the link for the BMC system of interest (e.g. witherspoon)
+    - Click the "host_fw_debug.tar" link in order to download the tar file.
+    - On your Power Linux system, untar the file with the following command:
+      ```
+      $ tar -xvf host_fw_debug.tar
+      ```
+
+    - Run the following to rename the untarred files:
+      ```
+      $ for file_name in host_fw_debug* ; do mv $file_name ${file_name#host_fw_debug} ; done
+      ```
+
+    The files of interest are as follows:
+    eSEL.pl
+    hbotStringFile
+    hbicore.syms
+
+    An error log binary parser is also required:
+    - Go to https://sourceforge.net/projects/linux-diag/files/ppc64-diag/
+    - Download the latest release version of the source tar zipped.
+    - Extract the tarball and compile. Refer to README in the source.
+    - On successful compilation, get `opal-elog-parse` binary.
+
+    **Generating error log from SEL binary data:**
+
+    Run the following command:
+
+    Create a directory and copy all the required binaries and script.
+
+    ```
+    $ export PATH=$PATH:<path to directory>
+    ```
+
+    ```
+    $ eSEL.pl -l SEL_data -p decode_obmc_data --op
+    ```
+    where `SEL_data` is the file containing SEL binary data and option "--op"
+    will refer "opal-elog-parse" instead or errl.
+
+    This command will generate a SEL_data.txt file.
+
